CVE-2024-25133
📋 TL;DR
This vulnerability allows a developer account on a Hive-enabled OpenShift Dedicated cluster to escalate privileges to cluster-admin level by executing arbitrary commands on the hive/hive-controllers pod. It affects OpenShift Dedicated environments with Hive ClusterDeployments resource enabled. The flaw requires developer-level access to exploit.
💻 Affected Systems
- OpenShift Dedicated
⚠️ 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).

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Full cluster compromise where an attacker gains cluster-admin privileges, allowing complete control over all cluster resources, data exfiltration, and potential lateral movement to other systems.
Likely Case
Privilege escalation from developer to cluster-admin within a single cluster, enabling unauthorized access to sensitive resources and potential data breaches.
If Mitigated
Limited impact if proper RBAC controls, network segmentation, and pod security policies are implemented to restrict developer account capabilities.
🎯 Exploit Status
Exploitation requires developer-level access and knowledge of Kubernetes/Hive pod command execution. No public exploit code has been released.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: OpenShift Dedicated with Hive fix included in PR #2306
Vendor Advisory: https://access.redhat.com/security/cve/CVE-2024-25133
Restart Required: Yes
Instructions:
1. Update OpenShift Dedicated cluster to version containing Hive fix PR #2306. 2. Apply the Hive operator update. 3. Restart hive-controllers pods. 4. Verify patch application via version check.
🔧 Temporary Workarounds
Restrict Hive ClusterDeployments Access
linuxTighten RBAC controls to limit developer account access to Hive ClusterDeployments resources
kubectl apply -f restricted-rbac.yaml
Implement Pod Security Policies
linuxApply strict pod security policies to prevent command execution on hive-controllers pod
kubectl apply -f pod-security-policy.yaml
🧯 If You Can't Patch
- Implement strict RBAC controls to limit developer account permissions to minimum required
- Enable audit logging for all Hive ClusterDeployments resource access and monitor for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Check if Hive ClusterDeployments resource is enabled and verify Hive operator version is prior to fix PR #2306Check Version:
oc get hiveoperator -n hive -o jsonpath='{.status.version}'Verify Fix Applied:
Verify Hive operator version includes fix from PR #2306 and test developer account cannot execute commands on hive-controllers pod📡 Detection & Monitoring
Log Indicators:
- Unauthorized command execution attempts on hive-controllers pod
- RBAC permission escalation events
- Cluster-admin privilege acquisition from developer accounts
Network Indicators:
- Unusual API calls to Hive ClusterDeployments resources
- Suspicious pod-to-pod communication patterns
