2 Factor Authentication Update

I don't believe this, i can't basically do a SQL injection, CSRF or XSS! Everything i wanted to do is basically either encrypted or if i injection a simple character like ", it says service unavailable. This application can be considered very secure it terms of encryption and of good standard if weighing it against the OWASP top ten. Even if i enter a value like 10, this value will be encrypted with this:
