Telnet: GAMSoft Telsrv DoS

This signature detects attempts to exploit a known flaw in GAMSoft Telsrv. A successful exploit would result in a Denial of Service (DoS).

Extended Description

GAMSoft Telsrv telnet server is prone to a trivial denial-of-service attack. If a malicious user were to connect to port 23 and supply a username of approximately 4550 characters, the telnet application would crash. Restarting the service is required to regain normal functionality. In some cases, Telsrv will return an error message that contains a valid username and password in plain-text format. This can be used to gain unauthorized access to the telnet server.
