"The version of Palo Alto Networks PAN-OS running on the remote host is 7.1.x or 8.x prior to 8.1.15. 
It is, therefore, affected by a OS command injection vulnerability in the PAN-OS management 
interface that allows authenticated administrators to execute arbitrary OS commands with root privileges.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.");
