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 Certificate Authentication

Abstract
No está definida la autenticación del certificado de cliente X509 para el punto final HTTPS de Kubelet.
Explanation
Los Kubelets pueden autenticar clientes, pero el paquete de la autoridad de certificación (CA) empleado para verificar el certificado del cliente no está definido en la configuración de Kubelet. Debido a que los Kubelets son los agentes principales de Kubernetes empleados para administrar la carga de trabajo de equipo del componente, 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 de Kubelet no contiene el campo clientCAFile que especifica el paquete de CA utilizado para verificar los certificados de cliente.

apiVersion: kubelet.config.k8s.io/v1beta1
kind: KubeletConfiguration
