CVE-2025-4057
📋 TL;DR
A vulnerability in ActiveMQ Artemis allows password reuse across separate Custom Resource dependencies when generated by the activemq-artemis-operator. This affects systems using the operator to manage ActiveMQ Artemis deployments where multiple CRs might share the same generated password instead of unique ones.
💻 Affected Systems
- ActiveMQ Artemis
- activemq-artemis-operator
⚠️ 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).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers could gain unauthorized access to multiple Artemis instances if they compromise one password, potentially leading to data exposure, message interception, or service disruption across the deployment.
Likely Case
Password reuse across deployments could allow lateral movement within a cluster if one instance is compromised, but requires existing access to the environment.
If Mitigated
With proper network segmentation and access controls, impact is limited to potential password reuse within the same security boundary.
🎯 Exploit Status
Requires existing access to the Kubernetes/OpenShift environment and knowledge of the password reuse pattern
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check specific Red Hat advisories (RHSA-2025:12355, RHSA-2025:12473, RHSA-2025:8147)
Vendor Advisory: https://access.redhat.com/security/cve/CVE-2025-4057
Restart Required: Yes
Instructions:
1. Update activemq-artemis-operator to patched version per Red Hat advisories. 2. Update ActiveMQ Artemis instances. 3. Regenerate passwords for existing deployments. 4. Restart affected services.
🔧 Temporary Workarounds
Manual Password Rotation
linuxManually rotate passwords for all ActiveMQ Artemis instances to ensure unique credentials
# Update password in each ActiveMQ Artemis CR:
kubectl edit activemqartemis <instance-name>
# Or use operator CLI to regenerate credentials
🧯 If You Can't Patch
- Implement strict network segmentation between ActiveMQ Artemis instances
- Monitor for unusual authentication patterns across instances
🔍 How to Verify
Check if Vulnerable:
Check if activemq-artemis-operator is generating passwords that are reused across multiple Custom Resources in your deploymentCheck Version:
kubectl get deployment activemq-artemis-operator -o jsonpath='{.spec.template.spec.containers[0].image}'Verify Fix Applied:
Verify operator version is updated per Red Hat advisories and passwords are unique across CRs📡 Detection & Monitoring
Log Indicators:
- Multiple authentication attempts with same credentials across different instances
- Failed authentication followed by successful access with same credentials elsewhere
Network Indicators:
- Unusual cross-instance authentication patterns
- Connections from unexpected sources to multiple Artemis instances
