"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 command injection vulnerability in the management plane of Palo Alto Networks PAN-OS software enables
    an authenticated administrator to execute arbitrary OS commands as root.

    The security risk posed by this issue is significantly minimized when CLI access is restricted to a
    limited group of administrators.

    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.");
