As a result, users could be denied access to mail and other servlet based resources. Novell has published an advisory and workaround in TID 10067329. The server should be deactivated or de-installed if not necessary. 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. Approx. 1 hour Yes http://www.securityfocus.com/bid/3697/exploit/ Yes Yes Medium 7 8 7 7 Medium Nessus is able to do the same check. A CGI scanner as like N-Stealth, Whisker or Nikto may be able to detect this flaw too.
