CVE-2025-36124
📋 TL;DR
IBM WebSphere Application Server Liberty versions 17.0.0.3 through 25.0.0.8 contain a vulnerability where JMS messaging configuration is not properly enforced, allowing remote attackers to bypass security restrictions. This affects organizations using these versions with JMS messaging enabled.
💻 Affected Systems
- IBM WebSphere Application Server Liberty
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could bypass authentication or authorization controls to access restricted JMS resources, potentially leading to unauthorized message consumption, injection, or data exposure.
Likely Case
Attackers could bypass intended JMS security policies to access messaging queues/topics they shouldn't have access to, potentially reading or injecting messages.
If Mitigated
With proper network segmentation and JMS security configurations, impact is limited to potential policy bypass within already-trusted network segments.
🎯 Exploit Status
Requires knowledge of JMS configuration and access to the messaging interface
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 25.0.0.9 and later, or apply interim fix
Vendor Advisory: https://www.ibm.com/support/pages/node/7242027
Restart Required: Yes
Instructions:
1. Upgrade to Liberty 25.0.0.9 or later. 2. Apply IBM interim fix if available. 3. Restart the Liberty server.
🔧 Temporary Workarounds
Disable JMS messaging
allTemporarily disable JMS messaging features if not required
Modify server.xml to remove or comment out JMS messaging configuration
Restrict network access
allLimit network access to JMS ports and interfaces
Configure firewall rules to restrict access to JMS ports (typically 7276, 7286, 5556)
🧯 If You Can't Patch
- Implement strict network segmentation around Liberty servers
- Enhance JMS security with additional authentication layers
🔍 How to Verify
Check if Vulnerable:
Check Liberty version using server command: server version
Check Version:
server version
Verify Fix Applied:
Verify version is 25.0.0.9 or later, or check for applied interim fixes
