Palo Alto Networks PAN-OS 8.1.x < 8.1.17 Memory Corruption

critical Nessus Plugin ID 155307

Language:

Synopsis

The remote PAN-OS host is affected by a memory corruption vulnerability.

Description

The version of Palo Alto Networks PAN-OS running on the remote host is 8.1.x prior to 8.1.17. It is, therefore, affected by a memory corruption vulnerability. This vulnerability exists in Palo Alto Networks GlobalProtect portal and gateway interfaces that enables an unauthenticated network-based attacker to disrupt system processes and potentially execute arbitrary code with root privileges. The attacker must have network access to the GlobalProtect interface to exploit this issue.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to PAN-OS 8.1.17 or later
