Input Validation Filter
allAdd input validation to sanitize the integral_min parameter before processing
Modify index.php to add: if(!is_numeric($_GET['integral_min'])) { die('Invalid input'); }
Web Application Firewall
allDeploy a WAF with SQL injection protection rules
🧯 If You Can't Patch
- Implement strict input validation for all GET/POST parameters
- Deploy a web application firewall with SQL injection detection rules
🔍 How to Verify
Check if Vulnerable:
Test by sending a SQL injection payload to the integral_min parameter: /index.php?integral_min=1' OR '1'='1Check Version:
Check ECTouch version in admin panel or read version.txt file in installation directoryVerify Fix Applied:
Test the same payload after patching - it should return an error or sanitized response instead of executing SQL📡 Detection & Monitoring
