External Secrets Operator is a Kubernetes operator that integrates external secret management systems. The external-secrets has a deployment called default-external-secrets-cert-controller, which is bound with a same-name ClusterRole. This ClusterRole has "get/list" verbs of secrets resources. It also has path/update verb of validatingwebhookconfigurations resources. This can be used to abuse the SA token of the deployment to retrieve or get ALL secrets in the whole cluster, capture and log all data from requests attempting to update Secrets, or make a webhook deny all Pod create and update requests. This vulnerability is fixed in 0.10.2.

GHSA-qwgc-rr35-h4x9 — External Secrets Operator vulnerable to privilege escalation

Affected: Go: github.com/external-secrets/external-secrets

### Details The external-secrets has a deployment called default-external-secrets-cert-controller, which is bound with a same-name ClusterRole. This ClusterRole has "get/list" verbs of secrets resources(https://github.com/external-secrets/external-secrets/blob/main/deploy/charts/external-secrets/templates/cert-controller-rbac.yaml#L49). It also has path/update verb of validatingwebhookconfigurations resources(https://github.com/external-secrets/external-secrets/blob/main/deploy/charts/external-secrets/templates/cert-controller-rbac.yaml#L27). As a result, if a malicious user can access the worker node which has this deployment. he/she can: 1. For the "get/list secrets" permission, he/she can abuse the SA token of this deployment to retrieve or get ALL secrets in the whole cluster, including the cluster-admin secret if created. After that, he/she can abuse the cluster-admin secret to do whatever he/she likes to the whole cluster, resulting in a cluster-level privilege escalation.

2. For the patch/update verb of validatingwebhookconfigurations, the malicious user can abuse these permissions to get sensitive data or lanuch DoS attacks:

For the privilege escalation attack, by updating/patching a Webhook to make it listen to Secret update operations, the attacker can capture and log all data from requests attempting to update Secrets. More specifically, when a Secret is updated, this Webhook sends the request data to the logging-service, which can then log the content of the Se…
