Title: Microsoft Windows Kerberos安全功能绕过漏洞

Description:

Microsoft Windows是美国微软（Microsoft）公司发布的一系列操作系统。Kerberos是美国麻省理工学院（MIT）开发的一套网络认证协议，它采用客户端/服务器结构，并且客户端和服务器端均可对对方进行身份认证（即双重验证），可防止窃听、防止replay攻击等。

Microsoft Windows的Kerberos中存在安全功能绕过漏洞，该漏洞源于Kerberos无法检查用户登录工作站的密码更改。远程攻击者可利用该漏洞在目标计算机上绕开Kerberos身份验证并解密受BitLocker保护的驱动器。

Severity: 低

Summary

Kerberos in Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8.1, Windows Server 2012 Gold and R2, and Windows 10 Gold and 1511 does not properly validate password changes, which allows remote attackers to bypass authentication by deploying a crafted Key Distribution Center (KDC) and then performing a sign-in action, aka "Windows Kerberos Security Feature Bypass."
