CVE-2024-25132

4.3 MEDIUM

📋 TL;DR

A denial-of-service vulnerability in OpenShift Dedicated's Hive hibernation controller allows attackers to crash the controller by creating malformed ClusterDeployment and ClusterSync resources. This affects OpenShift Dedicated environments using Hive for cluster lifecycle management. The vulnerability requires cluster-level permissions to exploit.

💻 Affected Systems

Products:
  • OpenShift Dedicated
Versions: OpenShift Dedicated versions prior to the fix
Operating Systems: Linux
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects environments using Hive for cluster management. Requires ability to create ClusterDeployment and ClusterSync resources.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete disruption of cluster hibernation functionality, potentially affecting cluster lifecycle operations and requiring controller restart.

🟠

Likely Case

Temporary denial of service to the Hive hibernation controller, disrupting automated cluster hibernation/resumption until controller restarts.

🟢

If Mitigated

Minimal impact with proper RBAC controls preventing unauthorized resource creation.

🌐 Internet-Facing: LOW - Requires authenticated access to the Kubernetes API with appropriate permissions.
🏢 Internal Only: MEDIUM - Internal users with cluster-admin or similar privileges could exploit this.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Requires cluster-level permissions to create specific Kubernetes resources. Exploitation involves creating malformed resources to trigger the panic.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check Red Hat advisory for specific fixed versions

Vendor Advisory: https://access.redhat.com/security/cve/CVE-2024-25132

Restart Required: Yes

Instructions:

1. Update OpenShift Dedicated to the patched version
2. Restart Hive hibernation controller components
3. Verify controller is functioning normally

🔧 Temporary Workarounds

Restrict Resource Creation

linux

Implement RBAC controls to restrict who can create ClusterDeployment and ClusterSync resources

kubectl create role --verb=create --resource=clusterdeployments,clustersyncs --namespace=hive

🧯 If You Can't Patch

  • Implement strict RBAC to prevent unauthorized users from creating ClusterDeployment/ClusterSync resources
  • Monitor for panic events in Hive controller logs and have restart procedures ready

🔍 How to Verify

Check if Vulnerable:

Check OpenShift Dedicated version against Red Hat advisory. Review if Hive controller has experienced recent panic events.

Check Version:

oc version

Verify Fix Applied:

Verify OpenShift version is patched per advisory. Confirm Hive controller is running without panic errors.

📡 Detection & Monitoring

Log Indicators:

  • Hive controller panic logs
  • ClusterDeployment creation with installed=true and hibernateAfter set
  • Unexpected controller restarts

Network Indicators:

  • Unusual API calls creating ClusterDeployment/ClusterSync resources

SIEM Query:

source="hive-controller" AND (panic OR "nil pointer" OR "accessing non-existing field")
