"The version of SonicWall SMA100 installed on the remote host is prior 9.0.0.4. It is, therefore, affected by a
directory traversal vulnerability. In SonicWall SMA100, an unauthenticated Directory Traversal vulnerability in 
the handleWAFRedirect CGI allows the user to test for the presence of a file on the server.

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