La seguridad de un software no es un software de seguridad. Nos preocupamos de cuestiones como la autenticación, el control de acceso, la confidencialidad, la criptografía y la gestión de privilegios.

Kubernetes Misconfiguration: Missing Kubelet Identity Verification

Abstract
La verificación de la identidad del servidor de Kubelets está deshabilitada cuando un servidor API de Kubernetes realiza conexiones SSL.
Explanation
Un servidor API de Kubernetes envía instrucciones a Kubelets para crear cargas de trabajo, consulta el estado de los recursos administrados por Kubelet y proporciona servicios de reenvío de puertos opcionales a Kubelets. De forma predeterminada, el servidor API no verifica el certificado de servicio de Kubelet antes de establecer la conexión. En consecuencia, esta conexión es vulnerable a un ataque del tipo "man-in-the-middle".

Ejemplo 1: El siguiente comando inicia un servidor API de Kubernetes sin especificar un paquete de certificado raíz para verificar el certificado de servicio de Kubelet con la marca --kubelet-certificate-authority.

...
spec:
  containers:
  - command:
    - kube-apiserver
    - --audit-log-maxage=50
    - --audit-log-maxbackup=20
    - --audit-log-maxsize=200
  image: gcr.io/google_containers/kube-apiserver-amd64:v1.6.0
