Palo Alto Networks PAN-OS 8.1.x < 8.1.13 / 9.0.x < 9.0.7 Vulnerability

high Nessus Plugin ID 344628

Synopsis

The remote PAN-OS host is affected by a vulnerability

Description

The version of Palo Alto Networks PAN-OS running on the remote host is 8.1.x prior to 8.1.13 or 9.0.x prior to 9.0.7. It is, therefore, affected by a vulnerability.

A stack-based buffer overflow vulnerability in the management server component of PAN-OS allows an authenticated user to upload a corrupted PAN-OS configuration and potentially execute code with root privileges.

This issue affects Palo Alto Networks PAN-OS 8.1 versions before 8.1.13; 9.0 versions before 9.0.7.
This issue does not affect PAN-OS 7.1.

Tenable has extracted the preceding description block directly from the PAN-OS security advisory.

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 8.1.13 / 9.0.7 or later
