Title

Local Path Provisioner: HelperPod Template Injection

Summary

Local Path Provisioner provides a way for the Kubernetes users to utilize the local storage in each node. Prior to 0.0.36, a malicious user with permission to edit the local-path-config ConfigMap in the local-path-storage namespace can manipulate the helperPod.yaml template used by rancher/local-path-provisioner. The helperPod.yaml template is loaded by the provisioner and used to create HelperPods during PVC provisioning and cleanup operations. However, the template is not sufficiently validated before use. Security-sensitive fields such as securityContext.privileged, hostPath volumes, and Linux capabilities can be injected into the template. When a PVC operation triggers HelperPod creation, the provisioner creates the HelperPod using the attacker-controlled template. This can result in a privileged pod running on the target node with the host root filesystem mounted. This may allow the attacker to access sensitive host files, read ServiceAccount tokens from other pods on the same node, access other tenants' local-path volume data, or modify files on the host node. This vulnerability is fixed in 0.0.36.

Esto puede resultar en un pod privilegiado ejecut\u00e1ndose en el nodo objetivo con el sistema de archivos ra\u00edz del host montado.

Prior to 0.0.36, a malicious user with permission to edit the local-path-config ConfigMap in the local-path-storage namespace can manipulate the helperPod.yaml template used by rancher/local-path-provisioner. The helperPod.yaml template is loaded by the provisioner and used to create HelperPods during PVC provisioning and cleanup operations. However, the template is not sufficiently validated before use. Security-sensitive fields such as securityContext.privileged, hostPath volumes, and Linux capabilities can be injected into the template. When a PVC operation triggers HelperPod creation, the provisioner creates the HelperPod using the attacker-controlled template. This can result in a privileged pod running on the target node with the host root filesystem mounted. This may allow the attacker to access sensitive host files, read ServiceAccount tokens from other pods on the same node, access other tenants\u0027 local-path volume data, or modify files on the host node. This vulnerability is fixed in 0.0.36."

Summary

Local Path Provisioner Vulnerable to HelperPod Template Injection

Details

Impact

A malicious user with permission to edit the local-path-config ConfigMap in the local-path-storage namespace can manipulate the helperPod.yaml template used by rancher/local-path-provisioner.

The helperPod.yaml template is loaded by the provisioner and used to create HelperPods during PVC provisioning and cleanup operations. However, the template is not sufficiently validated before use. Security-sensitive fields such as securityContext.privileged, hostPath volumes, and Linux capabilities can be injected into the template.

Example malicious HelperPod template:

apiVersion: v1
kind: Pod
metadata:
  name: helper-pod
spec:
  containers:
  - name: helper-pod
    image: docker.io/kindest/local-path-helper:v20230510-486859a6
    imagePullPolicy: IfNotPresent
    securityContext:
      privileged: true
    volumeMounts:
    - name: host-root
      mountPath: /host
  volumes:
  - name: host-root
    hostPath:
      path: /
      type: Directory

When a PVC operation triggers HelperPod creation, the provisioner creates the HelperPod using the attacker-controlled template. This can result in a privileged pod running on the target node with the host root filesystem mounted.

This may allow the attacker to access sensitive host files, read ServiceAccount tokens from other pods on the same node, access other tenants' local-path volume data, or modify files on the host node.

Expected Behavior:

The HelperPod template should not allow privileged containers.
The HelperPod template should not allow arbitrary hostPath mounts.
Security-sensitive fields in helperPod.yaml should be validated or rejected before the provisioner creates HelperPods.

Patches

This vulnerability is addressed by validating the HelperPod template loaded from the local-path-config ConfigMap before it is used to create HelperPods.

The fix ensures that unsafe fields such as privileged security contexts, hostPath volumes, and other dangerous pod security settings are rejected. This prevents an attacker with ConfigMap edit permission from injecting a malicious HelperPod template that grants access to the host node.

Previously, a malicious user could modify helperPod.yaml to cause the provisioner to create a privileged HelperPod with the host root filesystem mounted, potentially leading to node-level compromise and ServiceAccount token theft.

With this fix, HelperPod templates containing unsafe security-sensitive fields are denied, and only safe HelperPod configurations are accepted.

Patched versions of local-path-provisioner include releases v0.0.34 and later.

No patches are provided for earlier releases, as they do not include the necessary HelperPod template validation logic.

Workarounds

Users should upgrade to a patched version of local-path-provisioner to fully mitigate this vulnerability.

As a temporary mitigation, users can restrict write access to the local-path-config ConfigMap in the local-path-storage namespace. Only trusted administrators should be allowed to update this ConfigMap.

Users may also mark the ConfigMap as immutable after deployment:

kubectl -n local-path-storage patch configmap local-path-config \
  --type merge -p '{"immutable": true}'

Additionally, enabling Kubernetes Pod Security Admission for the local-path-storage namespace can provide defense in depth. For example, enforcing the baseline policy can prevent privileged HelperPods from being created even if the template is modified:

kubectl label namespace local-path-storage \
  pod-security.kubernetes.io/enforce=baseline \
  pod-security.kubernetes.io/warn=restricted

These mitigations reduce the risk of exploitation, but upgrading to a patched release is required to fully address the issue.
