Kubernetes Misconfiguration: API Server Anonymous Access

Abstract
Un servidor API de Kubernetes acepta solicitudes anónimas.
Explanation
Los servidores API de Kubernetes aceptan solicitudes anónimas de forma predeterminada si otros métodos de autenticación configurados no rechazan las solicitudes. Debido a que un servidor API es la entidad de administración central de un clúster, los atacantes pueden usar solicitudes anónimas para obtener acceso a las API de servicios sensibles a la seguridad y con protección insuficiente.

Ejemplo 1: La siguiente configuración inicia un servidor API de Kubernetes y permite solicitudes anónimas configurando la marca --anonymous-auth=true.

...
spec:
  containers:
    - command:
      - kube-apiserver
...
      - --anonymous-auth=true
...
