[原文]The telnet port in Arescom NetDSL 1000 router allows remote attackers to cause a denial of service via a series of connections with long strings, which causes a large number of login failures and causes the telnet service to stop.

	  If you flood the telnet configuration a couple dozen times with long
	strings, eventually the telnetd service flat out dies. Routing functions
	of the NetDSL continue to work fine as before. It is unknown whether only
	the telnetd service is affected, other means of remote configuration may
	have become unavailable as well.

Arescom NET DSL 1000 Series ADSL Router

- 漏洞讨论

The Arescom NETDSL 1000 Series ADSL router provides a telnet-based management interface for configuration. An attacker can crash this interface by repeatedly connecting and sending long strings (256 characters) when prompted for a password. This does not affect normal router function, but shuts down the management console until the router is powered down and restarted.
