Summary

During Operation Lunar Peek in November 2024, attackers exploited chained vulnerabilities, CVE-2024-0012 and CVE-2024-9474, to gain unauthenticated remote admin access across over 13,000 exposed Palo Alto Networks management interfaces. Individually, these CVEs were scored 9.3 and 6.9 (CVSS v4.0) or 9.8 and 7.2 (CVSS v3.1), with the lower score often falling below enterprise patch thresholds, leading to deprioritization. This incident highlights critical flaws in traditional vulnerability management, which often treats CVEs in isolation, failing to account for chained exploits, rapid nation-state weaponization of patches, stockpiled CVEs, identity-related vulnerabilities outside CVSS, and the accelerating volume of AI-discovered CVEs. NIST's NVD is already prioritizing KEV and federal critical software enrichment due to a 263% increase in CVE submissions since 2020, with projections of 70,135 CVEs for 2026.

Key takeaway

For security directors managing enterprise risk, relying solely on individual CVSS scores for vulnerability prioritization is insufficient and dangerous. You should immediately implement a chain-dependency audit for all KEV CVEs, compress KEV-to-patch SLAs to 72 hours for internet-facing systems, and integrate identity-surface controls into your vulnerability reporting pipeline to address human process gaps and agentic AI credentials. Proactively stress-test your pipeline capacity against projected 1.5x and 10x CVE volume increases to prepare for AI-accelerated discovery.

Key insights

Traditional CVSS-based vulnerability prioritization fails to account for chained exploits, rapid weaponization, and non-software identity gaps.

Principles

• Adversaries chain vulnerabilities, circumventing individual severity ratings.
• CVSS base scores are theoretical and ignore real-world exploitation context.
• Vulnerability management must extend beyond software CVEs to identity gaps.

Method

Prioritize vulnerabilities by auditing for chain dependencies, compressing KEV-to-patch SLAs, reporting KEV aging, and integrating identity-surface controls into the vulnerability pipeline.

In practice

• Audit KEV CVEs for co-resident vulnerabilities scored 5.0+.
• Implement 72-hour KEV-to-patch SLAs for internet-facing systems.
• Include help desk authentication and agentic AI credentials in vulnerability reporting.
