Known exploited vulnerability
CVE-2025-0108
The short answer
CVE-2025-0108 affects Palo Alto Networks Cloud NGFW and is rated high (CVSS 8.8). CISA added it to the Known Exploited Vulnerabilities catalog on 2025-02-18: attackers are using it, so patch it first.
What it is
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.
