Description: Lostmon reported a vulnerability in osCommerce. A remote user can conduct cross-site scripting attacks.
Several scripts in the 'admin' directory do not properly filter HTML code from user-supplied input in the 'page' parameter before
displaying the input. A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary
scripting code to be executed by the target user's browser. The code will originate from the site running the osCommerce software
and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including
authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the
site, or take actions on the site acting as the target user.
The following scripts are affected:
admin/banner_manager.php
admin/banner_statistics.php
admin/countr
ies.php
admin/currencies.php
admin/languages.php
admin/manufacturers.php
admin/newsletters.php
admin/orders_status.php
admin/products_attributes.php
admin/products
_expected.php
admin/reviews.php
admin/specials.php
admin/stats_products_purchased.php
admin/stats_products_viewed.php
admin/tax_classes.php
admin/tax_rates.php
adm
in/zones.php
The 'zpage' parameter in 'admin/geo_zones.php' is also affected.
The vendor was notified on October 3, 2006.

Impact: A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the
osCommerce software, access data recently submitted by the target user via web form to the site, or take actions on the site acting
as the target user.

###############################################
osCommerce contains a flaw that allows a remote cross site
scripting attack.This flaw exists because the application does
not validate 'page' param upon submission to multiple scripts
in /admin folder.This could allow a user to create a specially
crafted URL that would execute arbitrary code in a user's browser
within the trust relationship between the browser and the server,
leading to a loss of integrity.
The same situation is done in 'admin/geo_zones.php' but with
param 'zpage'.

VULNERABLE CODE
#######################
Arround the line 30 in banner_manager.php we
tep_redirect(tep_href_link(FILENAME_BANNER_MANAGER,
'page=' . $HTTP_GET_VARS['page'] . '&bID=' .
$HTTP_GET_VARS['bID']));
the page param is called directly , not sanitize.
arround line 115 we have a similar situation ,
we GET page param without sanitice in any GET request.
In all of scripts vulnerables, we have the same situation,
but with diferent code

this is a simple evil url but we can do some moore elaborate url
in conjuncion with other archives not vulnerables... like this:
http://localhost/catalog/admin/categories.php?action=new_product_preview
&read=only&pID=12&origin=stats_products_viewed.php?page=2[XSS-code]
