CVE-ID: CVE-2023-2728
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: Yes
DescriptionThe vulnerability allows a remote user to bypass implemented security restrictions.
The vulnerability exists due to improperly imposed security restrictions. A remote user can launch containers that bypass the mountable secrets policy enforced by the ServiceAccount admission plugin when using ephemeral containers.Kubernetes clusters are only affected if the ServiceAccount admission plugin and the kubernetes.io/enforce-mountable-secrets annotation are used together with ephemeral containers.
Update the affected package kubernetes1.23 to the latest version.
