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

high Nessus Plugin ID 134710

Synopsis

The remote PAN-OS host is affected by vulnerability

Description

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

- A predictable temporary filename vulnerability in PAN-OS allows local privilege escalation. This issue allows a local attacker who bypassed the restricted shell to execute commands as a low privileged user and gain root access on the PAN-OS hardware or virtual appliance. This issue affects only PAN-OS 8.1 versions earlier than PAN- OS 8.1.13. This issue does not affect PAN-OS 7.1, PAN-OS 9.0, or later PAN-OS versions. (CVE-2020-1981)

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 or later
