					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.
