Microsoft WMI Administration Tools ActiveX Buffer Overflow

Description

This module exploits a memory trust issue in the Microsoft WMI
Administration tools ActiveX control. When processing a specially crafted
HTML page, the WEBSingleView.ocx ActiveX Control (1.50.1131.0) will treat
the 'lCtxHandle' parameter to the 'AddContextRef' and 'ReleaseContext' methods
as a trusted pointer. It makes an indirect call via this pointer which leads
to arbitrary code execution.

This exploit utilizes a combination of heap spraying and the
.NET 2.0 'mscorie.dll' module to bypass DEP and ASLR. This module does not
opt-in to ASLR. As such, this module should be reliable on all Windows
versions.

The WMI Administrative Tools are a standalone download & install (linked in the
references).
