[*] [ REFLECTED CROSS-SITE SCRIPTING (XSS) ]

[-] [ INFO ]

This Issue has *not* been found into last tested version (1.3.9h) but
into all others versions. The "Quantity" field of Store Product don't
sanitizes user input before to show output back to user. This leads an
attacker to inject and execute arbitrary javascript and/or html code.

[-] [ EXPLOIT ]

http://[host]/index.php?main_page=shopping_cart (OR)

Your Shopping Cart Contents =>

[*] [ STORED CROSS-SITE SCRIPTING (XSS) ]

[-] [ INFO ]

You have to be logged as Admin. The "Zones Name & Code" fields of
Locations/Taxes don't sanitizes user input before to store it into
database and to show output back to user. This leads an attacker to
inject and execute arbitrary javascript and/or html code.

[-] [ EXPLOIT ]

http://[host]/[admin]/zones.php?page=1&action=new (OR)

Locations/Taxes => Zones

Zones Name: "><script>alert("XSS")</script>
Zones Code: "><script>alert("XSS")</script>

So, you inject evil code that can not be deleted. (">) destroy the
page structure so the Admin have to work directly on database
(phpmyadmin, etc.) to restore it and delete evil code.

...etc, others Stored XSS are presents on admin console.



[*] [ ARBITRARY FILE UPLOAD ]

upload arbitrary files on server (ie. backdoors, php shells, etc.)

Tools => Banner Manager => New Banner => Image: phpShell.php

The uploaded file will be located into:

http://[host]/images/phpShell.php
