Modify editCategories.php to use prepared statements: $stmt = $conn->prepare('UPDATE categories SET name=? WHERE id=?'); $stmt->bind_param('si', $name, $id);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting editCategories.php
Add WAF rule: SecRule REQUEST_URI "@contains editCategories.php" "id:1001,phase:2,deny,status:403,msg:'SQLi attempt blocked'"
🧯 If You Can't Patch
- Isolate the Stock Management System behind a reverse proxy with strict input filtering
- Implement network segmentation to limit database access from the web application server
🔍 How to Verify
Check if Vulnerable:
Test editCategories.php endpoint with SQL injection payloads like: editCategories.php?id=1' OR '1'='1Check Version:
Check application version in admin panel or readme filesVerify Fix Applied:
Verify that parameterized queries are implemented and test with SQL injection payloads to confirm they are blocked📡 Detection & Monitoring
