CVE-2025-4227: Palo Alto Networks Globalprotect

Low severity, CVSS 3.5. EPSS: 0.2% chance of exploitation in the next 30 days.

An improper access control vulnerability in the Endpoint Traffic Policy Enforcement https://docs.paloaltonetworks.com/globalprotect/6-0/globalprotect-app-new-features/new-features-released-in-gp-app/endpoint-traffic-policy-enforcement feature of the Palo Alto Networks GlobalProtect™ app allows certain packets to remain unencrypted instead of being properly secured within the tunnel. An attacker with physical access to the network can inject rogue devices to intercept these packets. Under normal operating conditions, the GlobalProtect app automatically recovers from this interception within one minute.

Affected products

• Palo Alto Networks Globalprotect: from 6.0.0, before 6.2.8 (fixed in 6.2.8); from 6.3.0, before 6.3.3 (fixed in 6.3.3)
