CVE-2024-5042 — Submariner-operator: rbac permissions can allow for the spread of node compromises

A flaw was found in the Submariner project. Due to unnecessary role-based access control permissions, a privileged attacker can run a malicious container on a node that may allow them to steal service account tokens and further compromise other nodes and potentially the entire cluster.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.5% (30-day exploitation probability)+6
  • Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Red Hat Red Hat Advanced Cluster Management for Kubernetes 2, Red Hat Red Hat Openshift Data Foundation 4.20, Red Hat RHODF-4.16-RHEL-9…).
  2. Apply the fixed version or the patch documented under Remediation.
  3. Search available logs for exploit probes matching the vulnerability class (privilege escalation), errors and authentication anomalies.

What should defenders know first?

CVE-2024-5042 is "Submariner-operator: rbac permissions can allow for the spread of node compromises", rated Medium. It affects Red Hat Advanced Cluster Management for Kubernetes 2 (Red Hat); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 6.6 describes technical severity. EPSS 0.51% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
