CVE-2023-40029 (GCVE-0-2023-40029)

Vulnerability from cvelistv5 – Published: 2023-09-07 22:11 – Updated: 2024-09-26 18:22

Title

Cluster secret might leak in cluster details page in Argo CD

Summary

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. 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.

GHSA-FWR2-64VR-XV9M

Vulnerability from github – Published: 2023-09-11 12:59 – Updated: 2023-09-11 12:59

Summary

Argo CD cluster secret might leak in cluster details page

Details

Impact

Argo CD Cluster secrets might be managed declaratively using Argo CD / kubectl apply. As a result, the full secret body is stored inkubectl.kubernetes.io/last-applied-configuration annotation.

https://github.com/argoproj/argo-cd/pull/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. 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.

Patches

The bug has been patched in the following versions:

2.8.3
2.7.14
2.6.15

Workarounds

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.

RHSA-2023:5029

Vulnerability from csaf_redhat - Published: 2023-09-08 13:00 - Updated: 2026-03-18 02:25

Summary

Red Hat Security Advisory: Red Hat OpenShift GitOps security update

Severity

Critical

Scope

2 vulnerabilities in this advisory, including CVE-2023-40029.

CVE-2023-40029

A flaw was found in the ArgoCD package, used by Red Hat GitOps, that allows cluster secrets to be managed declaratively using the `kubectl apply` functionality, resulting in the full secret body being stored in `kubectl.kubernetes.io/last-applied-configuration` annotation. Since ArgoCD has included the ability to manage cluster labels and annotations via its API, an attacker can retrieve sensitive authentication information by leveraging this capability, imposing a high impact on data confidentiality and integrity for the targeted ArgoCD cluster. To perform a successful attack, the malicious actor should have `clusters, get` RBAC access granted to its user.

9.9 (Critical)
