CyberSecurityUP 55af0d4634 NeuroSploit v3.3.0 — Autonomous MD-Agent Engine

Re-model the pentest agent into an autonomous, markdown-driven engine that
turns a URL into a full engagement and delegates execution to a locally
installed agentic CLI backend.

Engine (neurosploit_agent/ + ./neurosploit launcher):
- orchestrator composes ONE master prompt from the agent library + RL weights
- backends: auto-detect & drive Claude Code / Codex / Grok CLI (+ Claude
  subscription); headless, autonomous, isolated workdir
- mcp: Playwright MCP (.mcp.json) for browser-based proof-of-execution
- rl: bounded per-agent reinforcement-learning weights w/ per-tech affinity,
  persisted to data/rl_state.json
- models: latest registry incl. NVIDIA NIM provider (PR #28)
- cli: interactive URL prompt + one-shot `run`, `backends`, `agents`, --dry-run

Agent library (agents_md/, 213 total):
- 196 vuln specialists incl. modern LLM/AI, cloud/K8s, API/auth, advanced
  injection, protocol smuggling, logic/crypto/supply-chain classes
- 17 meta-agents: orchestrator, recon, exploit_validator,
  false_positive_filter, severity_assessor, impact_evaluator, reporter,
  rl_feedback + migrated expert roles
- scripts/build_agents.py data-driven builder; REGISTRY.md index

Docs: rewritten README.md, v3.3.0 RELEASE.md, .env.example (NVIDIA NIM, xAI,
engine vars).

Retire legacy Python orchestration (neurosploit.py + agent classes) to legacy/.

JWT Algorithm Confusion Specialist Agent

User Prompt

You are testing {target} for RS256-to-HS256 algorithm confusion in JWT verification.

Recon Context: {recon_json}

METHODOLOGY:

1. Obtain public key

Recover the RSA public key (jwks_uri, /pubkey, or derive from two tokens)

2. Forge

Re-sign a modified payload with HS256 using the public key bytes as the HMAC secret (jwt_tool -X k)

3. Confirm

Submit the forged token (e.g. admin) and confirm it is accepted

4. Report Format

For each CONFIRMED finding:

FINDING:
- Title: JWT Algorithm Confusion Specialist at [endpoint]
- Severity: Critical
- CWE: CWE-347
- Endpoint: [full URL]
- Vector: [parameter/header/flow]
- Payload: [exact payload/command]
- Evidence: [proof of exploitation]
- Impact: Forge arbitrary tokens using the public key as HMAC secret
- Remediation: Pin expected alg, separate verification keys by alg, reject alg switching

System Prompt

You are a JWT specialist. Report only when a forged token is accepted by the server granting changed claims. Inability to verify acceptance means no finding.
