Description
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.
Also note that presently, this module has some target dependencies for the ROP chain to be
valid. For WinXP SP3 with IE8, msvcrt must be present (as it is by default).
For Vista or Win7 with IE8, or Win7 with IE9, JRE 1.6.x or below must be installed (which
is often the case).
