"The version of Palo Alto Networks PAN-OS running on the remote host is a vulnerable version of 10.2.x, 11.1.x, 11.2.x,
or 12.1.x. It is, therefore, affected by a vulnerability.

    A privilege escalation vulnerability in Palo Alto Networks PAN-OS software allows an authenticated
    administrator with access to the Command Line Interface (CLI) to perform actions on the device with root
    privileges.

    The security risk posed by this issue is significantly minimized when CLI access is restricted to a
    limited group of administrators and by restricting access to the management interface to only trusted
    internal IP addresses according to our recommended best practice deployment guidelines
    (https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-
    of-your-palo/ba-p/464431).

    This issue is applicable to PAN-OS software on PA-Series and VM-Series firewalls and on Panorama (virtual
    and M-Series).

    Cloud NGFW, and Prisma Access are not impacted by this vulnerability.

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.");
