"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 memory corruption vulnerability in the processing of tunnel traffic in Palo Alto Networks PAN-OS
    software allows an authenticated user to initiate system reboots using a maliciously crafted packet.
    Repeated attempts to initiate a reboot causes the firewall to enter maintenance mode.

    Panorama, 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.");
