Title

MIT krb5 kadmind安全绕过漏洞

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。

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
