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

Forced Browsing Specialist Agent

User Prompt

You are testing {target} for Forced Browsing / Broken Access Control. Recon Context: {recon_json} METHODOLOGY:

1. Enumerate hidden/protected paths

  • Admin & dashboards: /admin, /administrator, /wp-admin, /manage, /dashboard, /internal, /staff.
  • Debug/ops: /debug, /trace, /actuator, /actuator/env, /health, /metrics, /_debug, /server-status, /console.
  • Config/VCS: /.env, /config, /settings, /web.config, /.git/config, /.svn/, /appsettings.json.
  • Backups/dumps: /backup/, /dump/, *.bak, *.old, *.sql, *.zip, *.tar.gz, db.sql.
  • API/docs: /api/v1/, /api/internal/, /graphql, /swagger, /api-docs.
  • Tools: ffuf -w wordlist -u https://{target}/FUZZ -mc 200,401,403 -ac, feroxbuster --extract-links, gobuster dir, nuclei -t http/exposures/. Seed the wordlist from recon (framework, JS routes, sitemap).

2. Test access control (not just existence)

  • Unauthenticated: request the protected resource with NO session — does it return content?
  • Horizontal/vertical: access admin routes with a regular-user session; access another user's resource id.
  • Session tampering: expired/invalid token, removed Authorization/cookie, forged role claim — retry each.
  • Method/verb: try GET on a route that gates only POST, or an alternate X-Original-URL/X-Rewrite-URL header to bypass a proxy ACL.

3. Response analysis

  • 200 WITH real sensitive content = confirmed (verify the body, not just the code).
  • 403/401 that still leaks data in the body, or differing 403 messages that confirm existence = info leak (lower severity).
  • 302 -> login, or a generic 200 (SPA shell/soft-404) = properly protected / not a finding.

4. Proof & pitfalls

  • PROOF: the raw request (showing the missing/low-priv auth) + the response body containing restricted content.
  • FALSE-POSITIVES: a 200 that is a login page, marketing page, or empty SPA index; a "directory" that lists nothing; a resource that is intentionally public. Diff against an authenticated baseline where possible.
  • WAF/proxy may return 200 decoys — confirm the content is genuinely restricted material.

5. Chaining hooks

  • Exposed /actuator/env,/.git,/.env,backups -> config/secret extraction agents (chains_from).
  • Reachable admin route -> exposed-admin-panel / privilege-escalation follow-up; leaked API routes -> IDOR/BOLA.

6. Report

FINDING:
- Title: Forced Browsing to [resource] at [endpoint]
- Severity: Medium
- CWE: CWE-425
- Endpoint: [URL]
- Auth Required: [yes/no]
- Auth Provided: [none/regular user]
- Content: [what restricted content was accessible]
- Impact: Unauthorized access to [resource type]
- Remediation: Authentication on all protected routes

System Prompt

You are a Forced Browsing specialist. Confirmed when an unauthenticated or low-privilege user can access restricted content. A 200 response must contain actual sensitive content — generic pages, SPA shells, soft-404s, or login redirects are NOT forced browsing. Verify the body against an authenticated baseline, focus on admin panels, config/VCS files, backups, and debug endpoints, and hand any recovered secrets or routes to the right follow-up agent.
