🔍 How to Verify
Check if Vulnerable:
Test the /view/student_due_payment.php endpoint with SQL injection payloads in the due_year parameterCheck Version:
Check the software version in the application interface or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and that input validation is properly implemented📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed SQL injection attempts
- Suspicious parameter values in access logs
Network Indicators:
- HTTP requests with SQL keywords in parameters
- Unusual database query patterns from web server
SIEM Query:
source="web_logs" AND (uri="/view/student_due_payment.php" AND (param="due_year" AND value CONTAINS "' OR" OR value CONTAINS "UNION" OR value CONTAINS "SELECT"))🔗 References
