Palo Alto Networks PAN-OS Authentication Bypass Vulnerability
CVE-2025-0108 is a security vulnerability in Palo Alto Networks PAN-OS, added to CISA KEV on February 18, 2025. Patch priority: Patch this week.
What it is
Palo Alto Networks PAN-OS contains an authentication bypass vulnerability in its management web interface. This vulnerability allows an unauthenticated attacker with network access to the management web interface to bypass the authentication normally required and invoke certain PHP scripts.
VulnCheck tracked exploitation 5 days before CISA's KEV listing. VulnCheck's broader catalog of in-the-wild exploitation evidence picked this up before it landed on CISA's formal list. Per-CVE fact about this entry; not a population claim about lead time in general.
Who's affected
Affects anyone behind a Palo Alto firewall or using GlobalProtect VPN. The firewall is the network edge; the VPN is how remote workers reach inside the perimeter — exploitation puts an attacker on the internal network without touching a workstation.
What to do
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.

CISA due date

EPSS
EPSS score: 98.5% — higher than 100% of all scored CVEs.
EPSS estimates the probability of exploitation activity in the next 30 days. Every entry on this site is already confirmed exploited, so read it as relative urgency among the things you still have open, not as permission to wait.
