Modify login.php to use prepared statements: $stmt = $conn->prepare('SELECT * FROM users WHERE username = ?'); $stmt->bind_param('s', $username);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns in login requests
Configure WAF to block requests containing SQL keywords like UNION, SELECT, INSERT, DELETE in Username parameter
🧯 If You Can't Patch
- Isolate the POS system on a separate network segment with strict firewall rules limiting access
- Implement network-based intrusion detection to monitor for SQL injection attempts
🔍 How to Verify
Check if Vulnerable:
Test the login.php endpoint with SQL injection payloads in the Username parameter (e.g., admin' OR '1'='1)Check Version:
Check software version in admin panel or review source code headers for version informationVerify Fix Applied:
Retest with SQL injection payloads after implementing fixes; successful login should only occur with valid credentials📡 Detection & Monitoring
