Modify login.php to use prepared statements: $stmt = $conn->prepare('SELECT * FROM users WHERE username = ? AND password = ?'); $stmt->bind_param('ss', $username, $password);
Web Application Firewall Rules
allBlock SQL injection patterns at the WAF level
Add WAF rule: SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"
Block patterns: UNION SELECT, OR 1=1, --, #, ;, '
🧯 If You Can't Patch
- Isolate the system behind a reverse proxy with strict input filtering
- Implement network segmentation to limit lateral movement if compromised
🔍 How to Verify
Check if Vulnerable:
Test login.php with SQL injection payloads like: username=admin' OR '1'='1&password=anything
Check Version:
Check system documentation or admin panel for version information
Verify Fix Applied:
Attempt SQL injection payloads and verify they are rejected or sanitized
