Kubernetes Misconfiguration: Improper Admission Controller Access Control

Abstract
Kubernetes API 服务器未配置任何准入控制器。
Explanation
准入控制器对向 Kubernetes API 服务器发出的请求进行验证和自定义设置。这些控制器可以实施安全控制，例如拒绝未经授权的特权请求、强制执行命名空间隔离、限制过多的资源请求等等。API 服务器不验证请求，因为没有准入控制器或启用了弃用的 AlwaysAdmit 准入控制器。

示例 1：以下配置启动了含 AlwaysAdmit 准入控制器的 Kubernetes API 服务器。

...
kind: Pod
...
spec:
  containers:
  - command:
    - kube-apiserver
    ...
    - --enable-admission-plugins=AlwaysAdmit,PodSecurityPolicy
    ...
