Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns targeting the vulnerable endpoint.
🧯 If You Can't Patch
- Block external access to '/AttendanceMonitoring/report/index.php' endpoint at network level
- Implement database monitoring for unusual query patterns and restrict database user permissions
🔍 How to Verify
Check if Vulnerable:
Test the '/AttendanceMonitoring/report/index.php' endpoint with SQL injection payloads in 'Attendance' and 'YearLevel' parameters.Check Version:
Check software version in admin panel or configuration files.Verify Fix Applied:
Verify that SQL injection attempts no longer succeed and that input validation is properly implemented.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed login attempts or parameter manipulation
Network Indicators:
- HTTP requests with SQL keywords in parameters
- Unusual traffic patterns to the vulnerable endpoint
SIEM Query:
source="web_logs" AND (uri="/AttendanceMonitoring/report/index.php") AND (param="*sql*" OR param="*union*" OR param="*select*" OR param="*sleep*")
