Palo Alto Networks Patches Potentially Serious Firewall Vulnerability

Palo Alto Networks has published 10 new security advisories, including one for a high-severity firewall authentication bypass vulnerability.

Palo Alto Networks on Wednesday published 10 new security advisories to inform customers about the impact of new and previously known vulnerabilities on its products.

The most important advisory seems to be for a flaw tracked as CVE-2025-0108, which the vendor described as a PAN-OS issue that allows an unauthenticated attacker with network access to the targeted firewall’s management interface to bypass authentication 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,” Palo Alto Networks explained.

The company has released patches for affected PAN-OS versions, as well as workarounds and mitigations, noting that exposure is significantly reduced if only trusted internal IP addresses are allowed to access the management interface.

Palo Alto has assigned the vulnerability a severity rating of ‘high’ based on a CVSS score of 7.8, but there is no evidence of in-the-wild exploitation and the company has assigned it a ‘moderate’ urgency rating. 

However, Assetnote researchers, who discovered CVE-2025-0108 while analyzing two Palo Alto firewall vulnerabilities that have been exploited in attacks, described it as a critical vulnerability that can lead to remote code execution if combined with another vulnerability.

Searchlight Cyber, which recently acquired Assetnote, on Wednesday disclosed technical details of the vulnerability. 

Another noteworthy advisory published by Palo Alto Networks on Wednesday describes CVE-2025-0110, a PAN-OS vulnerability that also has a severity rating of ‘high’ and an urgency rating of ‘moderate’. This is a command injection flaw, but its exploitation requires administrator privileges.

Advisories have also been published for medium-severity issues in the Cortex XDR agent (allows disabling the agent) and Cortex XDR Broker (unauthorized access), and PAN-OS (file read and file deletion).

One advisory describes recent Chromium updates (Palo Alto Networks’ Prisma Access Browser is based on Chromium). Other advisories inform customers that various third-party component vulnerabilities do not affect PAN-OS. 

None of the vulnerabilities described in the latest round of advisories has been exploited in the wild, according to Palo Alto Networks.
