[原文]Information leaks in IIS 4 through 5.1 allow remote attackers to obtain potentially sensitive information or more easily conduct brute force attacks via responses from the server in which (2) in certain configurations, the server IP address is provided as the realm for Basic authentication, which could reveal real IP addresses that were obscured by NAT, or (3) when NTLM authentication is used, the NetBIOS name of the server and its Windows NT domain are revealed in response to an Authorization request. NOTE: this entry originally contained a vector (1) in which the server reveals whether it supports Basic or NTLM authentication through 401 Access Denied error messages. CVE has REJECTED this vector; it is not a vulnerability because the information is already available through legitimate use, since authentication cannot proceed without specifying a scheme that is supported by both the client and the server.


[CNNVD]Microsoft IIS认证类函数泄露漏洞(CNNVD-200208-053)

        IIS 4至5.1版本中存在信息泄露漏洞。远程攻击者可借助(1)来自服务器的响应(揭露是否支持Basic或NTLM认证至401个访问拒绝错误消息),(2)某些配置中为Basic认证作为域提出的服务器IP地址,泄露被NAT掩盖的真实IP地址,或(3)使用NTLM认证时,服务器的NetBIOS名和它的Windows NT域在对认证请求的响应中被揭露。

Microsoft IIS supports Basic and NTLM authentication. Reportedly, the authentication methods supported by a given IIS server can be revealed to an attacker through the inspection of returned error messages, even when anonymous access is also granted.

When a valid authentication request is submitted for either message with an invalid username and password, an error message will be returned. This happens even if anonymous access to the requested resource is allowed. An attacker may be able to use this information to launch further intelligent attacks against the server, or to launch a brute-force password attack against a known username.
