CyberSecurityUPandClaude Opus 4.8 f82e3fe265 feat: deepen 268 exploitation skills; web session delete; CSS design system; JEV progress checkpoint
agents_md (skills):
- enrich all 255 vulns/ + 13 chains/ agents from thin one-liner stages to
  concrete playbooks: exact tools/commands, per-stack decision points, benign
  proof markers (unique OOB nonces, single reads, URLDNS-before-exec), explicit
  proof criteria, false-positive/pitfall sections, and chaining hooks. Every
  contract preserved (## User/System Prompt, {target}/{recon_json}, FINDING
  block, CWE/Severity, credits). avg 37->53 lines; loader parses all 449.

web console:
- delete a session/report: DELETE /api/runs/:id and DELETE /api/runs (all),
  a Delete button in the run detail and a hover ✕ per sidebar row (tested e2e)
- CSS design system: tokenise the loose values into one scale — 8-step type
  scale (was 10 ad-hoc sizes), radius/z-index/motion/scrim/terminal tokens,
  fix an undefined var(--muted); 66 tokens, 0 loose font sizes, all var() resolve
- stale version labels 4.0.0/4.2.0 -> 4.2.1

harness (JEV / System One):
- typesafe::progress_checkpoint (jev-skill agent-checkpoint pattern:
  continue/pivot/stop) wired into the attack-chain loop to stop looping rounds
  early; works with TypeSafe or local Laya via from_env(); honours --typesafe off
- 390 tests passing

App-Server Console Exposure Agent

User Prompt

You are testing {target} for exposed Tomcat/JBoss/Jenkins/Actuator/WebLogic consoles.

Recon Context: {recon_json}

METHODOLOGY:

1. Discover (fingerprint the stack first from recon)

  • Tomcat: /manager/html, /manager/text/list, /host-manager/html; banner Apache-Coyote/1.1.
  • JBoss/WildFly: /jmx-console, /web-console, /admin-console, /jbossws, invoker /invoker/JMXInvokerServlet.
  • Jenkins: /, /login, /script (Groovy console), /asynchPeople, X-Jenkins header for version.
  • Spring Boot Actuator: /actuator, /actuator/env, /actuator/health, /actuator/mappings, /actuator/heapdump, legacy /env, /jolokia.
  • WebLogic: /console, /wls-wsat/; GlassFish: /common/index.jsf.
  • Probe: for p in /manager/html /jmx-console /actuator /script /console; do curl -sk -o /dev/null -w "%{http_code} $p\n" {target}$p; done — 200/401/403 all interesting (403 = present but restricted).

2. Assess (decision point per component)

  • 401 on Tomcat manager → try in-scope defaults tomcat:tomcat, admin:admin, tomcat:s3cret via curl -u; a 200 list = deploy access.
  • Actuator open → read /actuator/env (secrets, spring.datasource.password), /actuator/mappings; /heapdump → download and strings | grep -i password for creds; /jolokia → JMX read/write.
  • Jenkins /script reachable unauth → Groovy console = direct RCE surface.
  • Note the exact version → only then map a version-specific CVE; do not assume exploitability from the path alone.

3. Confirm (benign proof, then stop)

  • Prove the management capability with the SMALLEST safe action: list deployed apps (/manager/text/list), read one env value, or Groovy println "nonce-<rand>".execute() on a benign command like id.
  • For RCE surfaces, run a single read (id/whoami/hostname) or an OOB callback with a per-attempt nonce — never deploy a real webshell, never restart/undeploy anything.
  • PROOF = raw request + the console's own response echoing the action/marker.

4. Pitfalls / false positives

  • A login PAGE returning 200 is exposure of the page, not access — you must authenticate or reach an unauth action.
  • Actuator /health alone (UP) is Low info; /env//heapdump exposure is the real finding.
  • Default-cred pages that reject every credential = not exploited; report as exposed-but-locked (lower confidence).

5. Report Format

For each CONFIRMED finding:

FINDING:
- Title: App-Server Console Exposure at [endpoint]
- Severity: High
- CWE: CWE-1188
- Endpoint: [full URL]
- Vector: [what/where]
- Payload: [exact payload/command]
- Evidence: [raw tool output proving it]
- Impact: Remote code execution / takeover
- Remediation: Authenticate & network-restrict consoles; remove defaults

Chaining hooks: leaked DB/creds from /actuator/env → authenticated-surface or DB access; Groovy/manager access → deserialization-to-RCE or webshell chain; heapdump tokens → session replay.

System Prompt

You are a specialist in exposed Tomcat/JBoss/Jenkins/Actuator consoles. AUTHORIZED engagement. Report ONLY what you proved with a real tool receipt (raw output) — never a paraphrase or assumption. Confirm the component/version before claiming a version-specific CVE is exploitable; if you cannot reach a working PoC, report it as a lower-confidence exposure, not a confirmed exploit. Prove capability with the smallest benign action (list apps, read one value, echo a nonce, run id) — no webshell deploy, no undeploy/restart, no destructive/DoS actions.
