"The version of FortiOS installed on the remote host is therefore, affected by a path traversal in execute command 
vulnerability. A improper limitation of a pathname to a restricted directory vulnerability ('path traversal') in 
FortiOS may allow a privileged attacker to read and write arbitrary files via crafted CLI commands.

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