Advisory Details:

A Cross Site Scripting(XSS) vulnerability has been found in Litecart CMS

1) Reflected Cross-Site Scripting (XSS) in Litecart-1.3.4

The vulnerability exists due to insufficient sanitisation of user-supplied data 
in URI. A remote attacker can trick a logged-in user to open a specially 
crafted link and execute arbitrary HTML and script code in browser in context 
of the vulnerable website. Successful exploitation of the vulnerability may 
allow an attacker to change appearance of the web site, steal cookies of other 
users and forge check out pages. It is also possible to gain administrative 
access to the web site.

Vulnerable URL - 
http://127.0.0.1/litecart-1.3.4/public_html/en/printable_order_copy
Vulnerable Parameter - order_id

The exploitation example below uses the "prompt()" JavaScript function to 
display user cookie:

POC -

Here, checksum needs to be some valid checksum.
