Kubernetes Misconfiguration: Unbound Scheduler

YAML

Abstract

Un programador de Kubernetes acepta conexiones externas.

Explanation

El programador de Kubernetes determina dónde se ejecutan los pods. De forma predeterminada, un programador acepta solicitudes de conexiones externas. Desde una conexión externa, un atacante puede acceder a las API sensibles a la seguridad y con protección insuficiente.

Ejemplo 1: La siguiente configuración inicia un programador de Kubernetes sin una dirección de enlace.


...
spec:
  containers:
    - command:
      - kube-scheduler
    image: example.domain/kube-scheduler:v1.5.2
    imagePullPolicy: IfNotPresent
    ...
