'Name' => 'KingScada kxClientDownload.ocx ActiveX Remote Code Execution',
'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.
