Kubernetes Misconfiguration: Static Authentication Token

YAML

Abstract

Kubernetes API 服务器使用静态令牌来验证请求。

Explanation

Kubernetes API 服务器通过将持有者令牌与保存在静态令牌文件中的列表进行比较来验证请求。令牌文件以明文形式存储机密，且本质上是静态的。基于静态令牌的身份验证容易受到暴力攻击，且可能会在错误配置的环境中将访问凭据泄露给攻击者。要添加、替换或撤销令牌，必须重新启动 API 服务器。

示例 1：以下配置在使用 --token-auth-file 标记的情况下启动通过静态令牌验证请求的 Kubernetes API 服务器。


...
spec:
  containers:
  - command:
    - kube-apiserver
    ...
    - --token-auth-file=<filename>
    ...
