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

    A denial-of-service (DoS) vulnerability in Palo Alto Networks PAN-OS software enables an unauthenticated
    attacker to reboot a firewall by sending a specially crafted packet through the dataplane. Repeated
    attempts to initiate a reboot causes the firewall to enter maintenance mode.

    This issue is applicable to the PAN-OS software versions listed below on PA-Series firewalls, VM-Series
    firewalls, and Prisma Access software. This issue does not affect Cloud NGFW.

    We have successfully completed the Prisma Access upgrade for all customers, with the exception of those
    facing issues such as conflicting maintenance windows. Remaining customers will be promptly scheduled for
    an upgrade through our standard upgrade process.

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.");
