Silent-Storm Portal Other solutions Cross Site Scripting The remote host is running a vulnerable version of the Silent-Storm Portal. There are several input validation flaws available. There is a cross site scripting vulnerability affecting the file index.php and an attacker may corrupt the user database by creating a malformed username. Upgrade the software to the latest version. The server and CGI suite 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.
