🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes
Instructions:
No official patch available. Contact ESAFENET for updates and consider workarounds or alternative solutions.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for userId parameter to allow only expected characters
Implement parameterized queries or stored procedures in ReUserOrganiseService.java
Add input validation: userId.matches("[a-zA-Z0-9_-]+")
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns
Configure WAF to block requests containing SQL keywords in userId parameter
Implement rate limiting on /com/esafenet/servlet/user/ReUserOrganiseService endpoints
🧯 If You Can't Patch
- Isolate the vulnerable system from internet access and restrict internal network access
- Implement database-level protections: use least privilege accounts, enable audit logging, and review database permissions
🔍 How to Verify
Check if Vulnerable:
Test the ReUserOrganiseService endpoint with SQL injection payloads in userId parameterCheck Version:
Check ESAFENET CDG version through admin interface or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return appropriate error messages📡 Detection & Monitoring
