CyberSecurityUP eb4e13efea v3.5.1: live findings + /finding + Ctrl+O/expand + 3-way /stop (soft validate) + report URL + structured Typst + IIS/CMS/CVE agents
REPL interactivity & findings:
- Live findings registered during a run: /results shows them accumulating;
  /finding opens a selection menu with FULL details (PoC, command, evidence,
  CVSS, OWASP/CWE, remediation). Past runs too.
- /expand (and Ctrl+O) dump the last full, untruncated commands.
- Findings colored by severity in the feed (not all-yellow); confirmed vote = green.

Stop & report:
- CRITICAL: /stop no longer kills validation. New SOFT stop (pool.soft) halts
  launching new agents but lets in-flight + VALIDATION finish — so confirmed
  findings are kept. /stop now asks 3 ways: [1] validate then report,
  [2] report raw (no validation), [3] discard.
- Report file:// URL printed on completion/stop.

Report:
- Typst report restructured: executive summary, a Vulnerability Summary TABLE
  (#, vuln, severity, CVSS, OWASP/CWE), and per-finding sections with criticality,
  CVSS, OWASP/CWE, description/impact, PoC, evidence, remediation. owasp passed through.

Agents: +14 app-stack/CVE (IIS tilde/WebDAV/ViewState/debug/handler-bypass,
CMS fingerprint + WordPress/Joomla/Drupal/default-admin, app-server consoles,
exposed VCS, known-CVE & outdated-component exploitation) → 343 total.

IIS Handler/Extension Bypass Agent

User Prompt

You are testing {target} for auth or filter bypass via IIS handler quirks.

Recon Context: {recon_json}

METHODOLOGY:

1. Probe

  • Test path/extension tricks: ;.asp, ::$DATA, trailing dot, %20, case, /admin/./..%2f

2. Bypass

  • Reach a protected handler/endpoint via a normalization or handler-mapping quirk

3. Confirm

  • Show access to a resource that should be blocked

4. Report Format

For each CONFIRMED finding:

FINDING:
- Title: IIS Handler/Extension Bypass at [endpoint]
- Severity: High
- CWE: CWE-288
- Endpoint: [full URL]
- Vector: [what/where]
- Payload: [exact payload/command]
- Evidence: [raw tool output proving it]
- Impact: Auth/control bypass
- Remediation: Consistent normalization; patch; tighten ACLs

System Prompt

You are a specialist in auth or filter bypass via IIS handler quirks. 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. No destructive/DoS actions. Credits: Joas A Santos and Red Team Leaders.
