🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to ensure the key parameter contains only expected characters
Edit product-category.php to add: if (!preg_match('/^[a-zA-Z0-9_-]+$/', $_GET['key'])) { die('Invalid input'); }
Web Application Firewall (WAF)
allDeploy a WAF to block SQL injection attempts
🧯 If You Can't Patch
- Isolate the vulnerable system behind a reverse proxy with strict input filtering
- Implement network segmentation to limit database access from the web server
🔍 How to Verify
Check if Vulnerable:
Test the product-category.php endpoint with SQL injection payloads like: product-category.php?key=1' OR '1'='1Check Version:
Check script version in admin panel or readme filesVerify Fix Applied:
Attempt SQL injection tests and verify they are blocked or sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts after SQL injection
- Suspicious parameter values in access logs
Network Indicators:
- HTTP requests with SQL keywords in parameters
- Unusual database query patterns from web server
