"The version of Palo Alto Networks PAN-OS running on the remote host is 9.0.x prior to 9.0.3. It is, therefore, affected
by a command injection vulnerability. An authenticated, remote attacker can exploit this to execute arbitrary commands.

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