The version of Palo Alto Networks PAN-OS running on the remote host is 9.1.x prior to 9.1.2. 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.

- A NULL pointer dereference vulnerability in Palo Alto
Networks PAN-OS allows an authenticated administrator to
send a request that causes the rasmgr daemon to crash.
Repeated attempts to send this request result in denial
of service to all PAN-OS services by restarting the
device and putting it into maintenance mode. This issue
affects: PAN-OS 9.1 versions earlier than 9.1.2.
