Session hijacking via unchanged post-login identifier
Published May 13, 2020 · Updated Sep 16, 2024
Session fixation in PAN-OS GlobalProtect Portal 7.1, 8.0, 8.1 before 8.1.14, and 9.0 before 9.0.8 allows remote authenticated users to hijack sessions. After a successful user login, the portal retains the attacker-controlled PHP session identifier instead of issuing a new one, binding the authenticated state to a value already known to the attacker. Exploitation requires control of the user's pre-login session identifier and user interaction; it permits access to that user's portal session but does not interrupt service.
