CVE-2025-4227
GlobalProtect App: Interception in Endpoint Traffic Policy Enforcement
Description
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.
Weakness: CWE-319
