CVE-2025-29314
📋 TL;DR
This vulnerability allows attackers to intercept and access sensitive information transmitted via insecure Shiro cookies in OpenDaylight SFC. Attackers can perform man-in-the-middle attacks to steal session data or credentials. Organizations using OpenDaylight Service Function Chaining Sodium-SR4 or earlier versions are affected.
💻 Affected Systems
- OpenDaylight Service Function Chaining (SFC) Subproject
⚠️ Manual Verification Required

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of sensitive data including administrative credentials, session tokens, and configuration secrets leading to full system takeover.
Likely Case
Unauthorized access to sensitive information such as session data, potentially enabling privilege escalation or lateral movement.
If Mitigated
Limited impact with proper network segmentation and encryption controls in place, though risk remains for exposed systems.
🎯 Exploit Status
Exploitation requires man-in-the-middle position and knowledge of Shiro cookie handling. No authentication bypass needed once MITM is established.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions after Sodium-SR4
Vendor Advisory: https://blog.csdn.net/weixin_43959580/article/details/146018166
Restart Required: No
Instructions:
1. Upgrade OpenDaylight SFC to a version newer than Sodium-SR4. 2. Verify Shiro cookie configurations are properly secured. 3. Test functionality after upgrade.
🔧 Temporary Workarounds
Enable HTTPS/TLS encryption
allForce all communications to use encrypted HTTPS/TLS to prevent cookie interception
Configure SSL/TLS on all OpenDaylight interfaces
Disable HTTP-only access
Implement network segmentation
allIsolate OpenDaylight SFC instances from untrusted networks
Configure firewall rules to restrict access
Implement VLAN segmentation
🧯 If You Can't Patch
- Implement strict network access controls and segmentation
- Deploy TLS/SSL encryption for all communications and disable HTTP
🔍 How to Verify
Check if Vulnerable:
Check OpenDaylight SFC version and verify if using Sodium-SR4 or earlier. Review Shiro cookie configuration settings.Check Version:
Check OpenDaylight documentation or configuration files for version informationVerify Fix Applied:
Confirm version is newer than Sodium-SR4 and test that cookies are properly encrypted and secured.📡 Detection & Monitoring
