Description

The GlobalProtect Portal feature in PAN-OS does not set a new session
identifier after a successful user login, which allows session fixation
attacks, if an attacker is able to control a user's session ID.

This issue affects:

All PAN-OS 7.1 and 8.0 versions;

PAN-OS 8.1 versions earlier than 8.1.14;

PAN-OS 9.0 versions earlier than 9.0.8.
