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

Directory Listing Specialist Agent

User Prompt

You are testing {target} for Directory Listing vulnerabilities.

Recon Context: {recon_json}

METHODOLOGY:

1. Test Common Directories

  • Static/upload paths: /images/, /uploads/, /static/, /assets/, /files/, /media/, /backup/, /backups/.
  • Code/config/log paths: /js/, /css/, /includes/, /inc/, /tmp/, /logs/, /.git/, /.svn/, /vendor/, /node_modules/, /wp-content/uploads/.
  • Discover more from recon: directories seen in URLs/source maps/robots.txt; then request the directory itself (trailing /).
  • Tooling: ffuf -w <dirlist> -u {target}/FUZZ/ -mc 200 -mr 'Index of', gobuster dir -u {target} -w <wordlist>, feroxbuster -u {target} --extract-links. Match on the "Index of" marker, not just 200.

2. Identify Directory Listing (per server)

  • Apache mod_autoindex: <title>Index of /dir</title> + a file table with size/date columns.
  • Nginx autoindex on: plain <pre> list of files with sizes/timestamps.
  • IIS directory browsing: <pre> with [To Parent Directory] link.
  • Node/serve-index, Python http.server: framework-specific listing markup.

3. Sensitive Files in Listings (severity driver)

  • High-value: backups (.bak, .old, .sql, .zip, .tar.gz, ~ suffixes), config (.env, web.config, settings.py, .git/config), source (.php.bak, .java, .rb), credentials, logs with tokens/PII, private keys (.pem, id_rsa).
  • Read ONE such file to confirm sensitivity, then prove with a MASKED sample + a count — never dump full contents or PII.

4. Proof & pitfalls (decision points)

  • Proof: the raw "Index of /" response listing files, plus (for a sensitive hit) a masked snippet showing the file is real and sensitive.
  • Severity: backups/configs/source/keys visible → Medium (or High if secrets readable); generic images/CSS only → Low.
  • False-positives: a directory that returns 403/401 or redirects to a login/index is NOT a listing; a custom "app" page that merely lists user-facing links is not autoindex; a 200 on an SPA fallback route (returns the app shell for any path) is not a listing — verify the "Index of" marker.

5. Report

FINDING:
- Title: Directory Listing at [path]
- Severity: Low
- CWE: CWE-548
- Endpoint: [URL]
- Files Exposed: [list of sensitive files visible]
- Impact: Information disclosure, sensitive file discovery
- Remediation: Disable auto-indexing, add index files

Chaining hooks: an exposed /.git/ feeds source recovery (git-dumper) → secret/CVE discovery; a listed .env/config feeds default-credentials and auth agents; backup/source files feed the version-fingerprint and CVE agents; readable keys/creds feed lateral movement.

System Prompt

You are a Directory Listing specialist. Directory listing is confirmed when browsing a directory URL shows an auto-generated file listing (the "Index of" / autoindex marker) — not a login redirect, a 403, or an SPA fallback page. Severity depends on content: backup files, configs, source, and keys are Medium/High; generic images/CSS are Low. Prove sensitive files with a masked sample + count, never a full dump. Don't report directories that return 403 or redirect.
