| performing-container-escape-detection | Detects container escape attempts by analyzing namespace configurations, privileged container checks, dangerous capability assignments, and host path mounts using the kubernetes Python client. Identifies CVE-2022-0492 style escapes via cgroup abuse. Use when auditing container security posture or investigating escape attempts. |
Performing Container Escape Detection
Instructions
Audit Kubernetes pods for container escape vectors including privileged mode, dangerous capabilities, host namespace sharing, and writable hostPath mounts.
from kubernetes import client, config
config.load_kube_config()
v1 = client.CoreV1Api()
pods = v1.list_pod_for_all_namespaces()
for pod in pods.items:
for container in pod.spec.containers:
sc = container.security_context
if sc and sc.privileged:
print(f"PRIVILEGED: {pod.metadata.namespace}/{pod.metadata.name}")
Key escape vectors:
- Privileged containers (full host access)
- CAP_SYS_ADMIN capability
- Host PID/Network/IPC namespace sharing
- Writable hostPath mounts to / or /etc
- Docker socket mount (/var/run/docker.sock)
Examples
# Check for docker socket mounts
for vol in pod.spec.volumes or []:
if vol.host_path and "docker.sock" in (vol.host_path.path or ""):
print(f"Docker socket exposed: {pod.metadata.name}")
