Severity: 中

Patch Name: MIT krb5 kadmind安全绕过漏洞的补丁

Patch Description:

MIT krb5（又名MIT Kerberos 5）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。kadmind是其中的一个用于启动Kerberos管理服务器的服务程序，它运行在主Kerberos服务器，存储于KDC数据库中。 MIT krb5 kadmind中存在安全绕过漏洞。攻击者可利用该漏洞绕过安全限制，执行未授权操作。目前，供应商发布了安全公告及相关补丁信息，修复了此漏洞。

Formal description:

目前厂商已经发布了升级补丁以修复此安全问题，详情请关注厂商主页： http://web.mit.edu/~kerberos/

Summary

The check_rpcsec_auth function in kadmin/server/kadm_rpc_svc.c in kadmind in MIT Kerberos 5 (aka krb5) through 1.11.5, 1.12.x through 1.12.2, and 1.13.x before 1.13.1 allows remote authenticated users to bypass a kadmin/* authorization check and obtain administrative access by leveraging access to a two-component principal with an initial "kadmind" substring, as demonstrated by a "ka/x" principal.
