CyberRota Analysis
AI-GeneratedA vulnerability exists in the cluster-proxy service-proxy component of Red Hat Advanced Cluster Management for Kubernetes and multicluster-engine, allowing authenticated hub principals to exploit unrestricted impersonation permissions. By injecting an Impersonate-Group header, attackers can escalate their privileges to cluster-admin across all managed clusters, posing a significant risk to cluster security. Organizations utilizing these Kubernetes management solutions should prioritize patching this vulnerability to mitigate potential unauthorized access and privilege escalation.
Original NVD Description
A flaw was found in the cluster-proxy service-proxy component used in Red Hat Advanced Cluster Management for Kubernetes (RHACM) and multicluster-engine (MCE). The service-proxy appends impersonation group headers to proxied requests without first removing caller-supplied values, and the spoke ServiceAccount holds unrestricted impersonation permissions. An authenticated hub principal can inject an Impersonate-Group header to escalate to cluster-admin on every managed cluster.
