# API Reference: Auditing Kubernetes Cluster RBAC
|
|
|
|
## kubernetes (Python Client)
|
|
|
|
### Configuration
|
|
|
|
```python
|
|
from kubernetes import client, config
|
|
|
|
config.load_kube_config() # From ~/.kube/config
|
|
# or
|
|
config.load_incluster_config() # Inside a pod
|
|
```
|
|
|
|
### List ClusterRoles
|
|
|
|
```python
|
|
rbac = client.RbacAuthorizationV1Api()
|
|
roles = rbac.list_cluster_role()
|
|
for role in roles.items:
|
|
print(role.metadata.name)
|
|
for rule in role.rules or []:
|
|
print(f" verbs={rule.verbs} resources={rule.resources}")
|
|
```
|
|
|
|
### List ClusterRoleBindings
|
|
|
|
```python
|
|
bindings = rbac.list_cluster_role_binding()
|
|
for b in bindings.items:
|
|
print(b.metadata.name, "->", b.role_ref.name)
|
|
for s in b.subjects or []:
|
|
print(f" {s.kind}: {s.name}")
|
|
```
|
|
|
|
### List Pods (Security Context)
|
|
|
|
```python
|
|
v1 = client.CoreV1Api()
|
|
pods = v1.list_pod_for_all_namespaces()
|
|
for pod in pods.items:
|
|
for c in pod.spec.containers:
|
|
sc = c.security_context
|
|
if sc and sc.privileged:
|
|
print(f"PRIVILEGED: {pod.metadata.namespace}/{pod.metadata.name}")
|
|
```
|
|
|
|
## Key RBAC Resources
|
|
|
|
| Resource | API | Description |
|
|
|----------|-----|-------------|
|
|
| ClusterRole | `rbac.list_cluster_role()` | Cluster-wide permission definitions |
|
|
| ClusterRoleBinding | `rbac.list_cluster_role_binding()` | Binds roles to subjects cluster-wide |
|
|
| Role | `rbac.list_namespaced_role(ns)` | Namespace-scoped permissions |
|
|
| RoleBinding | `rbac.list_namespaced_role_binding(ns)` | Namespace-scoped binding |
|
|
| ServiceAccount | `v1.list_service_account_for_all_namespaces()` | Pod identities |
|
|
|
|
## Dangerous RBAC Patterns to Detect
|
|
|
|
| Pattern | Risk |
|
|
|---------|------|
|
|
| `verbs: ["*"], resources: ["*"]` | Equivalent to cluster-admin |
|
|
| `resources: ["secrets"], verbs: ["get"]` | Can read all secrets |
|
|
| `resources: ["pods/exec"]` | Can exec into containers |
|
|
| `subjects: system:authenticated` | All users get this role |
|
|
| `automountServiceAccountToken: true` | Token available in pod |
|
|
