🧯 If You Can't Patch
- Implement network segmentation to restrict access to the vulnerable endpoint
- Deploy database monitoring to detect unusual SQL queries and access patterns
🔍 How to Verify
Check if Vulnerable:
Check if the system version is 3.3 or earlier and if the /system/user/list endpoint accepts params[dataScope] parameterCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Test the vulnerable endpoint with SQL injection payloads to confirm they are properly sanitized or blocked📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed authentication attempts followed by SQL injection patterns
- Unexpected database errors in logs
Network Indicators:
- HTTP POST requests to /system/user/list with SQL keywords in parameters
