🔍 How to Verify
Check if Vulnerable:
Test the nameTxt parameter on the login page with time-based SQL injection payloads (e.g., ' OR SLEEP(5)--).Check Version:
Check the application version in the web interface or configuration files.Verify Fix Applied:
Retest the vulnerable parameter with SQL injection payloads to confirm they no longer cause delayed responses.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts with SQL-like patterns
Network Indicators:
- HTTP requests to login page with SQL keywords in parameters
- Unusual database query patterns from application server
SIEM Query:
source="web_logs" AND uri="*cse?cmd=LOGIN*" AND (param="*nameTxt*" AND value="*OR*" OR value="*SLEEP*" OR value="*WAITFOR*" OR value="*UNION*" OR value="*SELECT*" OR value="*--*" OR value="*/*")
