Modified

This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.

Current Description

An authentication bypass vulnerability in the Panorama context switching feature allows an attacker with network access to a Panorama's management interface to gain privileged access to managed firewalls. An attacker requires some knowledge of managed firewalls to exploit this issue. This issue does not affect Panorama configured with custom certificates authentication for communication between Panorama and managed devices. This issue affects: PAN-OS 7.1 versions earlier than 7.1.26; PAN-OS 8.1 versions earlier than 8.1.12; PAN-OS 9.0 versions earlier than 9.0.6; All versions of PAN-OS 8.0.
