- Implement strict access controls and monitor all traffic to the /e3api/api/main/ToJsonByControlName endpoint.
🔍 How to Verify
Check if Vulnerable:
Test the /e3api/api/main/ToJsonByControlName endpoint with SQL injection payloads in the 'data' parameter and observe database errors or unexpected responses.Check Version:
Check application configuration or contact vendor for version identification methods.Verify Fix Applied:
Verify that SQL injection payloads no longer produce database errors or unexpected data returns.📡 Detection & Monitoring
Log Indicators:
- Unusual database queries originating from the middleware application
- SQL syntax errors in application logs
- Multiple failed login attempts or data access patterns
Network Indicators:
- Unusual POST requests to /e3api/api/main/ToJsonByControlName with SQL keywords in parameters
- Outbound database connections from unexpected sources
SIEM Query:
source="application_logs" AND ("SQL syntax" OR "database error" OR "/e3api/api/main/ToJsonByControlName")🔗 References
