Modify PHP code to use prepared statements: $stmt = $conn->prepare('SELECT * FROM purchases WHERE id = ?'); $stmt->bind_param('i', $id);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns
Add WAF rule: SecRule ARGS:id "@detectSQLi" "id:1001,phase:2,deny"
🧯 If You Can't Patch
- Isolate the system from internet access and restrict to internal network only
- Implement strict network segmentation and monitor all database queries from the application
🔍 How to Verify
Check if Vulnerable:
Test /pages/purchase_add.php with SQL injection payloads like: ?id=1' OR '1'='1Check Version:
Check system version in admin panel or readme filesVerify Fix Applied:
Verify that SQL injection payloads no longer work and return proper error handling📡 Detection & Monitoring
