Official Description
The Telnet service in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP2, Vista Gold, SP1, and SP2, and Server 2008 Gold and SP2 allows remote Telnet servers to execute arbitrary code on a client machine by replaying the NTLM credentials of a client user, aka "Telnet Credential Reflection Vulnerability," a related issue to CVE-2000-0834.
