Upgrade k8s.io/kubernetes/pkg/kubelet to version 1.29.13, 1.30.9, 1.31.5, 1.32.1 or higher.
Overview
k8s.io/kubernetes/pkg/kubelet is a package that contains the libraries that drive the Kubelet binary. The kubelet is responsible for node level pod management. It runs on each worker in the cluster.
Affected versions of this package are vulnerable to Arbitrary Command Injection via the nodes/*/logs/query API. An attacker with the ability to query a node's '/logs' endpoint can execute arbitrary commands on the host by sending crafted requests to this endpoint.
Notes:
This is only exploitable if the node is a Windows worker node;
To detect whether this vulnerability has been exploited, you can examine your cluster's audit logs to search for node 'logs' queries with suspicious inputs.
