What it detects

This rule detects requests to the PAN-OS unauth path that use double-encoded traversal sequences to reach authenticated PHP scripts such as ztp_gate.php, matching the Nginx and Apache path confusion auth bypass for CVE-2025-0108 documented by Assetnote. The double-encoded %252e segments defeat the X-pan-AuthCheck routing and expose privileged management endpoints. This encoded traversal against ztp_gate indicates an attempt to bypass authentication on the management interface.
