CVE-2025-0108

CVE-2025-0108 is a critical-severity (CVSS 9.1) vulnerability in Palo Alto Networks PAN-OS. CISA added it to the Known Exploited Vulnerabilities catalog on February 18, 2025, which means exploitation in the wild has been confirmed; US federal agencies had to remediate it by March 11, 2025. CISA does not currently list it as used in ransomware campaigns. Palo Alto Networks has 16 vulnerabilities in the KEV catalog, 6 of them linked to ransomware.

An authentication bypass in the Palo Alto Networks PAN-OS software enables an unauthenticated attacker with network access to the management web interface to bypass the authentication otherwise required by the PAN-OS management web interface and invoke certain PHP scripts. While invoking these PHP scripts does not enable remote code execution, it can negatively impact integrity and confidentiality of PAN-OS. You can greatly reduce the risk of this issue by restricting access to the management web interface to only trusted internal IP addresses according to our recommended best practices 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 does not affect Cloud NGFW or Prisma Access software.
