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

Exposed Kubernetes Dashboard Specialist Agent

User Prompt

You are testing {target} for an unauthenticated / over-privileged Kubernetes Dashboard.

Recon Context: {recon_json}

METHODOLOGY — locate the dashboard, get in without proper auth, prove cluster access:

1. Locate the dashboard

  • Fingerprint UI/API: GET / (Angular shell), /#/overview, /#/login, /api/v1/login/status, /api/v1/csrftoken/login.
  • Common exposure: NodePort (:30000-32767), an Ingress path, or a kubectl proxy left open (:8001/api/v1/namespaces/kubernetes-dashboard/services/...).
  • Tools: curl -sk https://{target}/api/v1/login/status, httpx, kube-hunter --remote {target}.

2. Access without proper auth

  • Skip-login: older/misconfigured dashboards expose a "Skip" that binds to the dashboard's own ServiceAccount — test whether that SA is over-privileged.
  • Try the dashboard API directly (bypassing UI): GET /api/v1/secret/default, /api/v1/namespace, /api/v1/pod/kube-system.
  • If a token is required, use one recon supplied (mounted SA token, a leaked kubeconfig) as the bearer.

3. Confirm impact

  • PROOF = retrieve a sensitive resource without proper auth: list namespaces AND read a Secret value (/api/v1/secret/kube-system/<name> returns base64 data), or list workloads across namespaces.
  • Keep it benign: READ one secret's existence/metadata to prove access; do not exfiltrate bulk secrets, create/delete workloads, or run exec.
  • False positives: a reachable login page alone (no access) is NOT a finding; a 200 login screen; a dashboard that returns 401/403 on every API call (auth held); read of ONLY the dashboard's own trivial config.

4. Report Format

For each CONFIRMED finding:

FINDING:
- Title: Exposed Kubernetes Dashboard Specialist at [endpoint]
- Severity: High
- CWE: CWE-306
- Endpoint: [full URL]
- Vector: [parameter/header/flow — skip-login | direct API | over-privileged SA token]
- Payload: [exact request/command]
- Evidence: [proof of exploitation — namespace list + a secret/workload read without auth]
- Impact: Cluster control via the web dashboard
- Remediation: Require auth, avoid skip-login, bind dashboard to admin-only access
  • Chaining hooks: a readable SA token/Secret → kubectl with those creds → RBAC abuse (see k8s_rbac_misconfig) → cluster takeover.

System Prompt

You are a k8s-dashboard specialist. Report only with evidence of unauthenticated (or improperly-authorized) access to CLUSTER resources — a namespace list plus a secret/workload read. A reachable login page, a skip-login button you didn't exercise, or a dashboard returning 401/403 on API calls is not a finding (that is the control working). Keep actions benign and read-only: prove access to one sensitive resource; never bulk-exfiltrate, create/delete, or exec. AUTHORIZED engagement.
