# CVE PoC Generator

Research a CVE by ID, generate a standalone Python proof-of-concept script, and produce a detailed vulnerability report.

## Workflow

1. **NVD Lookup** - Query NVD API v2.0 for the CVE ID. Extract CVSS v3.1 score/vector, CWE IDs, CPE matches, advisory URLs, and patch links.
2. **Advisory Research** - Deep-dive vendor advisories, GitHub security advisories, Exploit-DB, and published write-ups. Identify root cause, affected versions, and attack vector details.
3. **PoC Generation** - Write a standalone Python script (`poc.py`) that demonstrates the vulnerability safely. Follow the script standards in `reference/poc-methodology.md`.
4. **Report Generation** - Write a comprehensive markdown report (`report.md`) with metadata, root cause analysis, risk assessment, and remediation guidance.

## NVD Data to Collect

| Field | Source | Usage |
|-------|--------|-------|
| CVE ID | NVD | Primary identifier |
| CVSS v3.1 Score + Vector | NVD | Risk scoring |
| CWE ID(s) | NVD | Vulnerability classification |
| CPE Matches | NVD | Affected products and versions |
| Advisory URLs | NVD references | Research sources |
| Patch Links | NVD references / vendor | Remediation guidance |
| Description | NVD | Vulnerability summary |
| Published / Modified dates | NVD | Timeline |

## Output

```
{OUTPUT_DIR}/
  artifacts/cve-pocs/CVE-XXXX-XXXXX/
    poc.py              # Standalone Python PoC script
  reports/cve-pocs/CVE-XXXX-XXXXX/
    report.md           # Detailed vulnerability report
```

## Invocation

```
/cve-poc-generator CVE-2024-XXXXX
```

The skill accepts a single CVE ID as argument. Multiple CVEs should be processed with separate invocations.

## Rules

1. **Least harm** - PoC scripts MUST demonstrate vulnerability without causing damage. Use detection/verification checks, not destructive payloads.
2. **Standalone scripts** - PoC must run independently with only standard Python libraries plus `requests`. No framework dependencies.
3. **Accurate scoring** - Use the exact CVSS score and vector from NVD. Do not fabricate or estimate scores.
4. **Source attribution** - Every claim in the report must cite its source (NVD, vendor advisory, CVE description).
5. **No emoji** - Use text severity labels only (CRITICAL, HIGH, MEDIUM, LOW, INFORMATIONAL).
6. **Verified data only** - Do not hallucinate CVE details. If NVD data is unavailable, state it explicitly.
7. **Safe defaults** - PoC scripts must default to read-only, non-destructive operations. Any potentially harmful action requires explicit `--confirm` flag.
