Technical Details & Description:
================================
Multiple non-persistent cross site scripting web vulnerabilities has been discovered in the official Authorize.net Payment Terminal v2.4.1,
the PayPal PRO Payment Terminal v3.1 and the Stripe Payment Terminal v2.2.1. The vulnerability allows remote attackers to inject own malicious
script codes with non-persistent attack vector to compromise client-site browser to web-application requests.
The non-persistent cross site scripting web vulnerabilities are located in the `item_description`,`fname`,`lname`,`address`,`city`,`email`
parameters of the `Billing Information` or `Payment Information` formular. Attackers are able to inject own malicious script code to the
`Description`,`Firstname`, `Lastname`,`Address`,`City`,`Email` input fields to manipulate client-side requests. The request method to
inject is post and the attack vector is non-persistent on client-side. In case the form is implemented to another web-service attackers
are able to exploit the bug by triggering an execute of the script code in the invalid exception-handling.
The PayPal PRO Payment Terminal v3.1 and Stripe Payment Terminal v2.2.1 impacts the same vulnerable script and is affected as well by
the simple validation vulnerability.
Successful exploitation of the vulnerabilities results in session hijacking, non-persistent phishing attacks, non-persistent external
redirects to malicious source and non-persistent manipulation of affected application modules.

Solution - Fix & Patch:
=======================
The vulnerability can be patched by a secure restriction of the input in combination with a parse or escape of the content.
After that the onkeyup checkFieldBack should be sanitized correctly to prevent script code executions for clients.
Security Risk:
==============
The security risk of the client-side cross site scripting vulnerability in the web-application is estimated as medium.
