What CISA says

Palo Alto Networks PAN-OS Management Interface Authentication Bypass Vulnerability

Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. Additionally, management interface for affected devices should not be exposed to untrusted networks, including the internet.

NVD description · published 2024-11-18

An authentication bypass in Palo Alto Networks PAN-OS software enables an unauthenticated attacker with network access to the management web interface to gain PAN-OS administrator privileges to perform administrative actions, tamper with the configuration, or exploit other authenticated privilege escalation vulnerabilities like CVE-2024-9474 https://security.paloaltonetworks.com/CVE-2024-9474 . The risk of this issue is greatly reduced if you secure access to the management web interface by restricting access to only trusted internal IP addresses according to our recommended best practice deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 . This issue is applicable only to PAN-OS 10.2, PAN-OS 11.0, PAN-OS 11.1, and PAN-OS 11.2 software. Cloud NGFW and Prisma Access are not impacted by this vulnerability.

How to check if you are exposed to CVE-2024-0012

Find every Palo Alto Networks PAN-OS system you or your clients run, including ones exposed to the internet. Those come first: CISA only lists flaws attackers are already using.
Compare each version with the fixed versions in the vendor advisory below. Where no fix exists yet, apply the vendor’s mitigation or take the system off the internet.
Run a credentialed vulnerability scan to catch the systems you missed, then check that the next scan no longer reports CVE-2024-0012.

US federal agencies had to fix this by 2024-12-09. Everyone else should treat that deadline as a guide: if it has passed, this is overdue.
