Certified Ethical Hacker (CEH) Practice Question

During a container-security engagement on a Kubernetes cluster, you gain an interactive shell inside a pod. The process hierarchy reveals the container is running in privileged mode, and a hostPath volume is mounted at /host that maps to the node's root filesystem (/). What single step would most effectively escalate your access to full root control of the underlying worker node?

  • Delete the compromised pod so Kubernetes will reschedule it on another node and hope it runs with higher privileges.

  • Execute chroot /host /bin/bash (or use nsenter) to switch the root to the mounted filesystem and obtain a root shell on the node.

  • Use kubectl port-forward to expose the pod and then SSH into the node from outside the cluster.

  • Flush all iptables rules from inside the container to disable the host firewall and pivot later.
