Summary
Gardener External DNS Management allows malicious google credential in DNS secret to lead to privilege escalation
Details
A security vulnerability was discovered in Gardener that could allow a user with administrative privileges for a Gardener project or a user with administrative privileges for a shoot cluster, including administrative privileges for a single namespace of the shoot cluster, to obtain control over the seed cluster where the shoot cluster is managed.
Am I Vulnerable?
This CVE affects all Gardener installations no matter of the public cloud provider(s) used for the seed clusters/shoot clusters.
Affected Components
gardener/external-dns-management
Affected Versions
- < 0.23.6
Fixed Versions
- >= 0.23.6
Important
The external-dns-management component may also be deployed on the seeds by the https://github.com/gardener/gardener-extension-shoot-dns-service extension when the extension is enabled. In this case, all versions of the shoot-dns-service extension <= v1.60.0 are affected by this vulnerability.
How do I mitigate this vulnerability?
Update to a fixed version.
