'Name' => 'Oracle MySQL for Microsoft Windows FILE Privilege Abuse',
'Description' => %q{
This module takes advantage of a file privilege misconfiguration problem
specifically against Windows MySQL servers. This module abuses the FILE
privilege to write a payload to Microsoft's All Users Start Up directory
which will execute every time a user logs in. The default All Users Start
Up directory used by the module is Windows 7 friendly.
