🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None
Restart Required: No
Instructions:
No official patch available. Vendor did not respond to disclosure.
🔧 Temporary Workarounds
Input Validation for URI.create
allImplement strict validation and allowlisting for URI inputs in the S3ClientFactory.java file.
Modify continew-system/src/main/java/top/continew/admin/system/factory/S3ClientFactory.java to validate URI inputs
Network Segmentation
allRestrict outbound network access from the affected server to only necessary services.
Configure firewall rules to limit outbound connections
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block SSRF patterns
- Monitor and alert on unusual outbound requests from the server
🔍 How to Verify
Check if Vulnerable:
Check if ContiNew Admin version is 4.2.0 or earlier and review the S3ClientFactory.java file for URI.create usage without validation.Check Version:
Check application version in admin interface or configuration files.Verify Fix Applied:
Test if URI.create function properly validates inputs and blocks unauthorized requests.📡 Detection & Monitoring
Log Indicators:
