Hack Remote PC using Microsoft Internet Explorer exec Command Use-After-Free Vulnerability

This module exploits a vulnerability found in Microsoft Internet Explorer (MSIE). When rendering an HTML page, the CMshtmlEd object gets deleted in an unexpected manner, but the same memory is reused again later in the CMshtmlEd::Exec() function, leading to a use-after-free condition. Please note that this vulnerability has been exploited in the wild since Sep 14 2012, and there is currently no official patch for it.

Exploit Targets

Internet Explorer 7 on XP SP2

Internet Explorer 8 on Windows 7
