CVE-2023-40029
Argo CD is a declarative continuous deployment for Kubernetes. Argo CD Cluster secrets might be managed declaratively using Argo CD / kubectl apply. As a result, the full secret body is stored in`kubectl.kubernetes.io/last-applied-configuration` annotation. pull request #7139 introduced the ability to manage cluster labels and annotations. Since clusters are stored as secrets it also exposes the `kubectl.kubernetes.io/last-applied-configuration` annotation which includes full secret body.
Leer descripción completaMostrar menos
In order to view the cluster annotations via the Argo CD API, the user must have `clusters, get` RBAC access. **Note:** In many cases, cluster secrets do not contain any actually-secret information. But sometimes, as in bearer-token auth, the contents might be very sensitive. The bug has been patched in versions 2.8.3, 2.7.14, and 2.6.15. Users are advised to upgrade. Users unable to upgrade should update/deploy cluster secret with `server-side-apply` flag which does not use or rely on `kubectl.kubernetes.io/last-applied-configuration` annotation. Note: annotation for existing secrets will require manual removal.
