Vulnerability Scanning & Assessment

Purpose

Enable Claude to perform comprehensive vulnerability assessments by directly analyzing dependency files, configuration files, and scan output — then generating prioritized, actionable reports. Claude identifies vulnerabilities, calculates risk, and prescribes remediation with version specifics.

Activation Triggers

This skill activates when the user asks about:

Scanning dependencies for known CVEs
Auditing requirements.txt, package.json, go.mod, pom.xml, Cargo.toml
Reviewing server configurations for security issues
CVSS scoring or severity calculation
Vulnerability assessment or security audit reports
Checking software versions against known exploits
Configuration hardening for nginx, Apache, SSH, Docker, Kubernetes
NVD, OSV, or CVE database queries

Prerequisites

pip install requests packaging jinja2 pyyaml

Optional enhanced tools:

nuclei — Template-based vulnerability scanner
trivy — Container and filesystem scanner
nmap with NSE scripts — Network vuln scanning
openvas — Full vulnerability management

Core Capabilities

1. Dependency Vulnerability Auditing

Claude can directly read and analyze dependency files:

When the user asks to audit dependencies:

Read the dependency file using Claude's Read tool or ask the user to paste it
Identify package manager from file format:
- requirements.txt / Pipfile.lock / pyproject.toml → Python/pip
- package.json / package-lock.json / yarn.lock → Node.js/npm
- go.mod / go.sum → Go modules
- pom.xml / build.gradle → Java/Maven/Gradle
- Cargo.toml / Cargo.lock → Rust/Cargo
- Gemfile.lock → Ruby/Bundler
- composer.lock → PHP/Composer
Extract exact versions for all direct and transitive dependencies
Query vulnerability databases — Claude can search NVD API, OSV, and GitHub Advisory Database for each package+version combination
Calculate CVSS v3.1 severity for each finding
Check for available patches — identify the minimum safe version
Generate prioritized remediation report

Use this command to run the automated audit:

python scripts/dependency_auditor.py --project-dir ./myapp --format json --output audit.json
python scripts/dependency_auditor.py --requirements requirements.txt --severity high,critical

Claude's native analysis — When running without scripts, analyze pasted dependency content directly:

Flag packages with >= , *, or missing version pins (supply chain risk)
Identify known high-risk packages (log4j, spring-core, struts, etc.)
Cross-reference with CISA KEV (Known Exploited Vulnerabilities) catalog

2. Configuration Security Auditing

Claude can directly read and analyze configuration files:

When the user asks to audit a configuration:

Nginx Audit Checklist

[ ] ssl_protocols — Must NOT include SSLv2, SSLv3, TLSv1, TLSv1.1
[ ] ssl_ciphers — Must not include RC4, DES, MD5, EXPORT ciphers

[ ] ServiceAccount — Disable automount if not needed
[ ] secrets — Use sealed secrets or external vaults

[ ] privileged — Must never be true in production

3. CVSS v3.1 Scoring

When the user asks to calculate CVSS or assess severity:

Claude can calculate CVSS v3.1 scores from the vector string or from a vulnerability description:

CVSS v3.1 Metrics:

Metric	Values	Description
Attack Vector (AV)	N/A/L/P	Network/Adjacent/Local/Physical
Attack Complexity (AC)	L/H	Low/High
Privileges Required (PR)	N/L/H	None/Low/High
User Interaction (UI)	N/R	None/Required
Scope (S)	U/C	Unchanged/Changed
Confidentiality (C)	N/L/H	None/Low/High
Integrity (I)	N/L/H	None/Low/High
Availability (A)	N/L/H	None/Low/High

Severity Ranges:

Score	Severity
0.0	None
0.1–3.9	Low
4.0–6.9	Medium
7.0–8.9	High
9.0–10.0	Critical

Example calculation:

Remote unauthenticated RCE: AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H → 10.0 (Critical)
Local privilege escalation: AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H → 7.8 (High)

python scripts/cvss_calculator.py --vector "AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"

4. Network Vulnerability Scanning Integration

When the user provides Nmap scan results or asks to scan for vulnerabilities:

Parse Nmap XML/grepable output for open services and versions
Map each service+version to known CVEs
Flag services with default credentials (check CVE/common credential lists)
Identify critical misconfigurations (anonymous FTP, open relay, telnet, etc.)
Provide targeted Nmap NSE script commands for deeper testing:

# Vulnerability scanning with NSE
nmap -sV --script vuln -p 80,443,22,21,3389 target.com

# SMB vulnerability check (EternalBlue, etc.)
nmap -p 445 --script smb-vuln* target.com

# SSL/TLS vulnerability check
nmap -p 443 --script ssl-enum-ciphers,ssl-heartbleed,ssl-poodle target.com

5. Vulnerability Report Generation

When the user asks for a vulnerability report:

Generate reports in this structure:

# Vulnerability Assessment Report
**Target:** [Target Name/IP Range]
**Date:** [Date]
**Scope:** [Authorized scope]
**Assessor:** [Name]

v3.0 Enhancements (2026 Update)

Risk-based prioritization beyond raw CVSS:

CVSS 4.0 — score with the current standard (Base/Threat/Environmental/Supplemental); show the vector string and note when only v3.1 data exists.
EPSS + CISA KEV — combine CVSS severity × EPSS exploit-probability × KEV membership. A medium-CVSS CVE that is in the CISA Known Exploited Vulnerabilities catalog or has high EPSS outranks a high-CVSS CVE with no exploitation signal. Always state "patch-first" order on this combined basis.
SBOM + VEX — generate a CycloneDX/SPDX SBOM of the project and emit VEX statements (affected / not_affected / fixed) so consumers know which CVEs are actually reachable.
Reachability analysis — flag whether a vulnerable function is actually called (call-graph/import reachability) to cut false-positive noise from transitive deps.
OSV.dev — query the OSV API for ecosystem-precise advisories (PyPI, npm, Go, crates, Maven) in addition to NVD.

Output rule: every finding row carries CVSS | EPSS | KEV(Y/N) | Reachable(Y/N/Unknown) | Fix.
