The version of Palo Alto Networks PAN-OS running on the remote host is 8.1.x prior to 8.1.22 or 9.0.x prior to 9.0.16 or 9.1.x prior to 9.1.13 or 10.0.x prior to 10.0.10 or 10.1.x prior to 10.1.5. It is, therefore, affected by a vulnerability.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- An improper handling of exceptional conditions vulnerability exists in the DNS proxy feature of Palo Alto
Networks PAN-OS software that enables a meddler-in-the-middle (MITM) to send specifically crafted traffic
to the firewall that causes the service to restart unexpectedly. Repeated attempts to send this request
result in denial-of-service to all PAN-OS services by restarting the device in maintenance mode.
