Bug vulnerability classDirectory Traversal
Bug descriptionIt is possible to escape out of the root directory of the scripting server by substituting a forward or backward slash for %5C. As a result, system information, such as environment and user information, could be obtained from the Netware server.
Bug solutionThe server should be deactivated or de-installed if not necessary. Apply the relevant patch (http://support.novell.com/servlet/filedownload/ftf/) and remove default files from the web server. Also, ensure the RCONSOLE password is encrypted and utilize a password protected screensaver for console access. To make it harder to find the server the daemon could be configured to listen at another port (e.g. 8081). Try to prevent unwanted connection attempts by filtering traffic with firewalling. Alternation of the application banner can confuse an attacker and let him determine the wrong software.
