OSVDB: OSVDB-69942

Microsoft WMI Administration Tools ActiveX Buffer Overflow

Posted Dec 22, 2010

Authored by MC, jduck, WooYun | Site metasploit.com

This Metasploit 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 Metasploit module does not opt-in to ASLR. As such, this module should be reliable on all Windows versions.
