CVE-2024-0012

CVE-2024-0012 is a critical authentication bypass (CWE-306) in the web management interface of Palo Alto Networks PAN-OS that lets an unauthenticated attacker with network access to that interface gain full PAN-OS administrator privileges. It is triggered simply by sending requests to an exposed management web interface, with no credentials or user interaction required. Once inside, the attacker can perform administrative actions, tamper with device configuration, and chain the bug with the related privilege escalation flaw CVE-2024-9474 for deeper compromise. Only PAN-OS 10.2, 11.0, 11.1 and 11.2 are affected; Cloud NGFW and Prisma Access are not, and risk is greatly reduced when the management interface is restricted to trusted internal IP addresses per vendor best practice. The flaw is being actively exploited: it was added to CISA KEV on 2024-11-18 with known ransomware use, and public reporting describes an ongoing campaign that has compromised more than 2,000 Palo Alto devices using this bug chained with CVE-2024-9474.

What to do: Upgrade PAN-OS 10.2, 11.0, 11.1 and 11.2 deployments to the patched releases listed in the vendor advisory (security.paloaltonetworks.com/CVE-2024-0012), ensuring the chained privilege escalation bug CVE-2024-9474 is also addressed. Until patched, never expose the management web interface to untrusted networks or the internet, and restrict access to trusted internal IP addresses only. Review device logs and configurations for signs of compromise (unexpected admin activity or configuration changes) and hunt for persistence on any internet-exposed device.
