The remote host is vulnerable to a Denial of Service (DoS) attack.
The remote host is running NetworkActive Web Server. NetworkActive Web Server is a small application that can be downloaded and run on any Windows desktop. An attacker exploiting this flaw would need to be able to connect to the server (typically on port 80) and send long requests. By sending enough requests, the attacker would be able to exhaust the resources of the Web server and cause it to crash.
Upgrade or patch according to vendor recommendations.
