'Name' => 'Oracle MySQL for Microsoft Windows MOF Execution',
'Description' => %q{
This module takes advantage of a file privilege misconfiguration problem
specifically against Windows MySQL servers (due to the use of a .mof file).
This may result in arbitrary code execution under the context of SYSTEM.
This module requires a valid MySQL account on the target machine.
