API Reference — Performing Kubernetes Penetration Testing

Libraries Used

  • subprocess: Execute kubectl commands for cluster reconnaissance and testing
  • json: Parse Kubernetes API JSON output

CLI Interface

python agent.py recon
python agent.py sa-perms [--namespace default]
python agent.py dashboards
python agent.py escape [--namespace default]

Core Functions

enumerate_cluster_info() — Cluster reconnaissance

Gathers: K8s version, node info (OS, kubelet), namespaces, services with types/ports.

test_service_account_permissions(namespace) — RBAC permission testing

Tests 8 permissions via kubectl auth can-i: get pods, list/get secrets, create pods, exec into pods, get nodes, list namespaces, create clusterroles.

scan_exposed_dashboards() — Find management interfaces

Searches for: dashboard, grafana, prometheus, kibana, jaeger, argocd, rancher, lens. Flags LoadBalancer/NodePort services as externally accessible.

check_pod_escape_vectors(namespace) — Container escape analysis

Detects: privileged mode, CAP_SYS_ADMIN/SYS_PTRACE, hostPath mounts (/, /etc, docker.sock, /proc, /sys), hostPID namespace, hostNetwork.

Dangerous Permissions (CRITICAL)

  • list secrets / get secrets --all-namespaces
  • create pods (pod creation with escalation)
  • create pods/exec (remote code execution)
  • create clusterroles (RBAC escalation)

Dependencies

System: kubectl with cluster access No Python packages required.
