AI-suggested

The vendor advisory states that to mitigate this vulnerability, patch access to the Search Custom Resource (CR) should be restricted exclusively to trusted and authorized hub administrators. This limits the ability of unauthorized users to modify the Collector.ImageOverride field and deploy arbitrary container images.

Description

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.
