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 7.1.x prior to 7.1.26 or 8.0.x prior to 8.1.13 or 8.1.x prior to 8.1.13 or 9.0.x prior to 9.0.6. It is, therefore, affected by a vulnerability.

- A race condition due to insecure creation of a file in a temporary directory vulnerability in PAN-OS allows for root privilege escalation from a limited linux user account. This allows an attacker who has escaped the restricted shell as a low privilege administrator, possibly by exploiting another vulnerability, to escalate privileges to become root user. (CVE-2020-2016)

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 7.1.26 / 8.1.13 / 8.1.13 / 9.0.6 or later
