Official description

In Eclipse BaSyx Helm Charts version 2.2.0 of the `aas-basyx-v2-full` chart, deployments with the bundled Keycloak enabled store the client secret of the `basyx-technical-user` OAuth2 client in cleartext in a Kubernetes ConfigMap. This client uses the client-credentials grant and its service account holds the realm `admin` role. The chart correctly writes `keycloak.technicalUser.clientSecret` to a Kubernetes Secret, but the template `basyx-keycloak-realm.yaml` also substitutes the same value into the Keycloak realm-import JSON, which is stored in the ConfigMap `<keycloak.fullnameOverride>-realm`. A principal that can read ConfigMaps but not Secrets in the release namespace, such as a holder of the built-in Kubernetes `view` ClusterRole, can read the client secret from the ConfigMap. They can then exchange it at the Keycloak token endpoint for an access token with the `admin` role. That token grants full create, read, update, delete and execute rights on all BaSyx repositories and registries in the deployment. The bundled Keycloak is disabled by default. No fixed release of the `aas-basyx-v2-full` chart exists. Affected users should migrate to the `basyx` chart, or deploy without the bundled Keycloak and rotate the `basyx-technical-user` client secret.

The underlying weakness: Cleartext Storage of Sensitive Information

The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

How developers prevent this class of flaw

  • When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to encrypt the data at rest.
  • In some systems/environments such as cloud, the use of double encryption (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
