Robust Vulnerability Extraction

This skill provides a more resilient method for extracting security data from scanner outputs.

Robust CVSS Extraction

Prioritize CVSS v3 across multiple sources, falling back to v2 if necessary.

def get_cvss_score(vuln):
    cvss = vuln.get('CVSS', {})
    if not cvss:
        return 'N/A'
    
    # Try V3 Scores first across sources
    for source in ['nvd', 'ghsa', 'redhat']:
        score = cvss.get(source, {}).get('V3Score')
        if score is not None:
            return score
            
    # Fallback to V2 Scores
    for source in ['nvd', 'ghsa', 'redhat']:
        score = cvss.get(source, {}).get('V2Score')
        if score is not None:
            return score
            
    return 'N/A'

Handling Missing Fields

Always provide defaults for optional fields to prevent None values in reports.

record = {
    'Package': vuln.get('PkgName', 'N/A'),
    'Version': vuln.get('InstalledVersion', 'N/A'),
    'CVE_ID': vuln.get('VulnerabilityID', 'N/A'),
    'Severity': vuln.get('Severity', 'N/A'),
    'CVSS_Score': get_cvss_score(vuln),
    'Fixed_Version': vuln.get('FixedVersion', 'N/A'),
    'Title': vuln.get('Title', 'N/A'),
    'Url': vuln.get('PrimaryURL', 'N/A')
}
