CVE-2024-3177

Summary

CVE-2024-3177 is a newly disclosed vulnerability in Kubernetes that allows users to bypass the mountable secrets policy enforced by the ServiceAccount admission plugin. This issue arises when containers, init containers, and ephemeral containers with the envFrom field populated are used. Normally, the policy ensures that pods running with a service account can only reference secrets specified in the service account’s secrets field. However, this vulnerability enables users to launch containers that can reference secrets outside of this restriction. Kubernetes clusters are susceptible to this issue only if the ServiceAccount admission plugin and the kubernetes.io/enforce-mountable-secrets annotation are configured together.
