Описание
A flaw was found in acm-search-v2-rhel9. An attacker with administrative privileges on the hub cluster, specifically with patch access to the Search Custom Resource (CR), could exploit a vulnerability in the Collector.ImageOverride field. This allows the attacker to deploy an arbitrary container image across all managed clusters. The consequence is remote code execution (RCE), enabling the attacker to execute commands and potentially access sensitive information across the entire fleet of managed clusters.
Отчет
This is an Important vulnerability in Red Hat Advanced Cluster Management for Kubernetes. A highly privileged user with patch access to the Search CR on the hub cluster can replace the collector image, leading to fleet-wide remote code execution and secret exfiltration across all managed clusters. This is due to the propagation of the Collector.ImageOverride field to all managed clusters.
Меры по смягчению последствий
To mitigate this issue, restrict patch access to the Search Custom Resource (CR) to only trusted and authorized hub administrators. This limits the ability of unauthorized principals to modify the Collector.ImageOverride field and deploy arbitrary container images across the managed fleet.
