CVE-2024-0012

Palo Alto Networks PAN-OS Management Interface Authentication Bypass Vulnerability. Exploitation in the wild is confirmed by CISA, not predicted, and the vulnerability is known to be used in ransomware campaigns. Federal agencies were required to remediate by 2024-12-09 (that deadline has passed); treat that date as the outer bound for your own environment. The fix is in the vendor advisory: Palo Alto Networks Security Advisories, linked below.

Senserva AI Opinion for CVE-2024-0012

An unauthenticated attacker who can reach a PAN-OS web management interface can bypass authentication entirely with this flaw, rated Critical at CVSS 9.8 with a maximum 100% EPSS score. It was added to KEV on 2024-11-18 during active mass exploitation of exposed Palo Alto management interfaces, and ransomware use is confirmed. Firewalls and VPN concentrators are the affected products, meaning the compromise happens at the network's control point.

Do this: Audit every Palo Alto device for internet-exposed management interfaces right now, then patch and review admin audit logs for unknown logins.
