What is CVE-2024-5651?

A vulnerability exists in the Red Hat Fence Agents Remediation operator that enables a low-privilege user to execute arbitrary commands through the --ssh-path and --telnet-path arguments. By creating a specially crafted FenceAgentsRemediation, an unauthorized actor can manipulate the operator's pod, resulting in Remote Code Execution (RCE). This exploitation facilitates privilege escalation, allowing potential access to a service account running the operator and escalating further to a service account with cluster-admin privileges, compromising the entire system's integrity.
