- 漏洞描述

The Microsoft Windows 2000 Telnet service contains a flaw that may allow a malicious user to access accounts which should not be accessible. The issue is triggered when a special set of characters is used as a prefix to the username supplied (in place of a domain name). This flaw causes the service to search the domain, and any trusted domains, for the specified user. It is possible that the flaw may allow an attacker to authenticate from normally inaccessible common domain accounts such as the guest account. This flaw may result in an attacker gaining telnet access via an exposed account as described above.
