npx mdskill add automateyournetwork/netclaw/nvd-cveSearch the National Vulnerability Database for CVEs and retrieve detailed vulnerability information
- Helps identify known vulnerabilities by CVE ID or keyword for security audits and remediation
- Uses the NVD API and MCP script to fetch CVSS scores, weaknesses, and affected configurations
- Analyzes input parameters to determine the correct search method and returns structured data
- Delivers results in JSON format with detailed vulnerability metrics and references

# NVD CVE Vulnerability Search
## Available Tools
### 1. `get_cve` — Look Up a Specific CVE by ID
```bash
NVD_API_KEY=$NVD_API_KEY python3 $MCP_CALL "python3 -u $NVD_MCP_SCRIPT" get_cve '{"cve_id":"CVE-2023-20198"}'
```
**Parameters:**
- `cve_id` (required): The CVE identifier, e.g., `CVE-2023-20198`
- `concise` (optional, default `false`): Set `true` for brief output (ID, description, CVSS score only)
**Returns:** Full CVE details including:
- CVSS v3.1 and v2.0 scores, severity, vector string
- Exploitability and impact scores
- CWE weakness identifiers
- References with tags (Vendor Advisory, Patch, Exploit, etc.)
- Affected configurations (CPE entries)
### 2. `search_cve` — Search CVEs by Keyword
```bash
NVD_API_KEY=$NVD_API_KEY python3 $MCP_CALL "python3 -u $NVD_MCP_SCRIPT" search_cve '{"keyword":"Cisco IOS XE 17.9"}'
```
**Parameters:**
- `keyword` (required): Search term, e.g., `"Cisco IOS XE"`, `"NX-OS 10.2"`, `"OpenSSL 3.0"`
- `exact_match` (optional, default `false`): Require exact keyword match
- `concise` (optional, default `false`): Brief output per CVE
- `results` (optional, default `10`): Number of results to return (max 2000)
**Returns:** List of matching CVEs with full details, plus total count.
## When to Use
- **Post-health-check vulnerability scan**: After `show version` reveals the IOS-XE/NX-OS version, search NVD for known CVEs
- **Security audit enrichment**: Cross-reference running config features (HTTP server, SNMP, SSH) against CVEs
- **Incident response**: Look up specific CVE IDs mentioned in advisories
- **Compliance reporting**: Document known vulnerabilities and remediation status
- **Upgrade planning**: Compare CVE exposure between current and target versions
## Vulnerability Audit Workflow
### Step 1: Extract Software Version
From a device health check, extract the software version (e.g., `IOS-XE 17.9.4a`).
### Step 2: Search NVD for Version-Specific CVEs
```bash
NVD_API_KEY=$NVD_API_KEY python3 $MCP_CALL "python3 -u $NVD_MCP_SCRIPT" search_cve '{"keyword":"Cisco IOS XE 17.9.4","results":20}'
```
### Step 3: Get Details for Critical/High CVEs
For each CVE with CVSS >= 7.0, pull full details:
```bash
NVD_API_KEY=$NVD_API_KEY python3 $MCP_CALL "python3 -u $NVD_MCP_SCRIPT" get_cve '{"cve_id":"CVE-2023-20198"}'
```
### Step 4: Exposure Correlation
Cross-reference CVE requirements against the device running config:
| CVE | Requires | Running Config | Exposed? |
|-----|----------|---------------|----------|
| CVE-2023-20198 | HTTP/HTTPS server enabled | `ip http server` present | **YES** |
| CVE-2023-20273 | Web UI accessible | `ip http secure-server` + no ACL | **YES** |
| CVE-2024-XXXXX | OSPF enabled | `router ospf 1` present | **YES** |
### Step 5: Produce Vulnerability Report
```
Vulnerability Audit — YYYY-MM-DD
Device: R1 | IOS-XE 17.9.4a
CRITICAL (CVSS >= 9.0):
CVE-2023-20198 (CVSS 10.0) — IOS-XE Web UI privilege escalation
Exposure: CONFIRMED — ip http server enabled
Remediation: Upgrade to 17.9.4a+ or disable ip http server
HIGH (CVSS >= 7.0):
CVE-2023-20273 (CVSS 7.2) — Web UI command injection
Exposure: CONFIRMED — ip http secure-server, no ACL
Remediation: Apply access-class to HTTP server or upgrade
MEDIUM (CVSS >= 4.0):
[none found]
Summary: 2 CRITICAL (2 exposed), 0 HIGH, 0 MEDIUM
```
### Step 6: Search by Feature Keywords
When auditing specific features, search for feature-specific CVEs:
```bash
# SNMP vulnerabilities
NVD_API_KEY=$NVD_API_KEY python3 $MCP_CALL "python3 -u $NVD_MCP_SCRIPT" search_cve '{"keyword":"Cisco SNMP remote code execution","results":10}'
# BGP vulnerabilities
NVD_API_KEY=$NVD_API_KEY python3 $MCP_CALL "python3 -u $NVD_MCP_SCRIPT" search_cve '{"keyword":"Cisco BGP denial of service","results":10}'
# SSH vulnerabilities
NVD_API_KEY=$NVD_API_KEY python3 $MCP_CALL "python3 -u $NVD_MCP_SCRIPT" search_cve '{"keyword":"Cisco IOS SSH vulnerability","results":10}'
```
## CVSS Severity Mapping
| CVSS Score | Severity | Action Timeline |
|-----------|----------|-----------------|
| 9.0 - 10.0 | CRITICAL | Immediate remediation required |
| 7.0 - 8.9 | HIGH | Remediate within 1 change window |
| 4.0 - 6.9 | MEDIUM | Remediate in next maintenance window |
| 0.1 - 3.9 | LOW | Document and track |
## Fleet-Wide Vulnerability Scan
Run version discovery across all devices, then batch-search NVD for each unique version:
```bash
# Step 1: Get version from each device
PYATS_TESTBED_PATH=$PYATS_TESTBED_PATH python3 $MCP_CALL "python3 -u $PYATS_MCP_SCRIPT" pyats_run_show_command '{"device_name":"R1","command":"show version"}'
# Step 2: Search NVD for each unique version found
NVD_API_KEY=$NVD_API_KEY python3 $MCP_CALL "python3 -u $NVD_MCP_SCRIPT" search_cve '{"keyword":"Cisco IOS XE 17.9.4","results":20,"concise":true}'
```
Produce a fleet vulnerability matrix:
```
┌──────────┬───────────────────┬──────────┬──────┬──────┬────────┐
│ Device │ Software Version │ CRITICAL │ HIGH │ MED │ Action │
├──────────┼───────────────────┼──────────┼──────┼──────┼────────┤
│ R1 │ IOS-XE 17.9.4a │ 2 │ 3 │ 5 │ URGENT │
│ R2 │ IOS-XE 17.12.1 │ 0 │ 1 │ 2 │ PLAN │
│ SW1 │ IOS-XE 16.12.4 │ 5 │ 8 │ 12 │ URGENT │
└──────────┴───────────────────┴──────────┴──────┴──────┴────────┘
```
## GAIT Audit Trail
Record vulnerability scans in GAIT:
```bash
python3 $MCP_CALL "python3 -u $GAIT_MCP_SCRIPT" gait_record_turn '{"input":{"role":"assistant","content":"NVD vulnerability scan on R1 (IOS-XE 17.9.4a): 2 CRITICAL (CVE-2023-20198, CVE-2023-20273), 3 HIGH, 5 MEDIUM.
