* Advisory ID: DRUPAL-SA-CONTRIB-2016-019 * Project: Drupal Commerce [1] (third-party module) * Version: 7.x * Date: 2016-April-06 * Security risk: 9/25 ( Less Critical) AC:Basic/A:None/CI:None/II:None/E:Theoretical/TD:Default [2] * Vulnerability: Information Disclosure

-------- DESCRIPTION ---------------------------------------------------------

This module enables you to build an online store that uses nodes to display products through the use of product reference fields. The default widget for those fields is an autocomplete textfield similar to the taxonomy term reference field's autocomplete widget. As you type in the textfield, the Commerce Product module returns a JSON array of matching product SKUs / titles for you to select.

The module doesn't sufficiently restrict access to the autocomplete path under the default configuration of the field. A visitor to the website could browse directly to the autocomplete path to see a list of products that would ordinarily be returned to the autocomplete JavaScript to populate the autocomplete dropdown. Default parameters on the function used to generate this list cause it to bypass the product access control check that would ordinarily restrict product visibility to end users based on your site's permissions.

This vulnerability is mitigated by the fact that an attacker must know what the autocomplete path is and what arguments to include in it to generate a valid response based on your site's architecture. Additionally, in most eCommerce sites, product SKUs and titles are not by themselves considered private information.
