The remote host is vulnerable to a Denial of Service (DoS) attack.
The remote host is running Caudium Web Server. The version being run is vulnerable to an attack where a malformed URI causes the web server to stop responding to requests. An attacker exploiting this flaw would only need to be able to connect to the Webserver and issue an HTTP 'GET' request.
Upgrade to version 1.4.4 RC2 or higher.
