Cve Triage
CVE lookup and triage — map discovered services/versions to known CVEs via the cve_lookup tool, score by CVSS/exploitability, and prioritize what to verify first.

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

CVE Triage
Turn version/banner evidence from recon into a prioritized, exploitability-aware list of CVEs worth verifying. Use this after fingerprinting a service, when a banner or Server: header reveals a product and version, or whenever the target exposes software with a known version.
The cve_lookup tool
VulnClaw ships a read-only cve_lookup tool backed by NVD:
- Keyword search —
cve_lookup(query="Apache httpd 2.4.49", limit=5)returns
the top CVEs sorted by CVSS, highest first.
- CVE-ID detail —
cve_lookup(query="CVE-2021-44228")returns the full record
plus best-effort exploit / PoC repositories discovered on GitHub.
It performs no egress to the target and is safe during recon. Without an NVD_API_KEY it still works (lower rate limit); set one for heavier use.
Workflow
- Extract product + version from recon — service banners,
Serverheaders,
JS bundles, login footers, package manifests. A precise version string (OpenSSH 8.2p1, nginx 1.18.0) yields far better matches than a bare name.
- Query
cve_lookupwith" ". Pull the detail record for
any high/critical hit by re-querying its CVE-ID.
- Score & prioritize — see
references/cve-triage-workflow.md. Rank by CVSS,
then by exploit availability, then by exposure (is the vulnerable surface actually reachable on this target?).
- Confirm version applicability — match the target's version against the
CVE's affected cpe range before claiming it. Banner ≠ proof of vulnerability.
- Record findings with the CVE-ID, CVSS, and the evidence that maps this
target to it. Mark unconfirmed version-only matches as needs-manual-review, not verified.
Pitfalls
- A keyword match is a hypothesis, not a finding — version ranges and backported
patches mean a banner version can be patched in place.
- GitHub "PoC" repos are unverified third-party code; treat as leads, never run
blindly against a target.
- Prefer the CVSS base score for triage, but let exploit availability and real
exposure override raw score when prioritizing verification effort.
