This Metasploit module exploits a stack overflow in Novell iPrint Client 5.30. When passing an overly long string via the "target-frame" parameter to ienipp.ocx an attacker can execute arbitrary code. NOTE: The "operation" variable must be set to a valid command in order to reach this vulnerability.
