What is CVE-2024-9779?
CVE-2024-9779 is a high-severity vulnerability in Red Hat Advanced Cluster Management for Kubernetes 2, published on 17 Dec 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
A flaw was found in Open Cluster Management (OCM) when a user has access to the worker nodes which contain the cluster-manager or klusterlet deployments. The cluster-manager deployment uses a service account with the same name "cluster-manager" which is bound to a ClusterRole also named "cluster-manager", which includes the permission to create Pod resources. If this deployment runs a pod on an attacker-controlled node, the attacker can obtain the cluster-manager's token and steal any service account token by creating and mounting the target service account to control the whole cluster.
Weakness: CWE-266
