We detected the remote web server is running WorldClient for MDaemon. This web server enables attackers with the proper username and password combination to access locally stored mailboxes. In addition, earlier versions of WorldClient suffer from buffer overflow vulnerabilities, and web traversal problems (if those are found the Risk factor is higher).

Make sure all usernames and passwords are adequately long and that only authorized networks have access to this web server's port number (block the web server's port number on your firewall).
