SA-CONTRIB-2014-075 - Biblio Autocomplete - SQL injection and Access Bypass

This module provides functionality for AJAX based auto-completion of fields in the Biblio node type (provided by the Biblio module) using previously entered values and third party services.

The submodule “Biblio self autocomplete” for previously entered values doesn’t sufficiently sanitize user input as it is used in a database query.

Additionally, the AJAX autocompletion callback itself was not properly secured, thus potentially allowing any visitor access to the data, including the anonymous user.

CVE identifier(s) issued

• CVE-2014-5249: SQL Injection
• CVE-2014-5250: Access Bypass

Versions affected

Drupal core is not affected. If you do not use the contributed Biblio Autocomplete module,
there is nothing you need to do.

Solution

Install the latest version:

• If you use the Biblio Autocomplete module for Drupal 6.x, upgrade to Biblio Autocomplete 6.x-1.1.
• If you use the Biblio Autocomplete module for Drupal 7.x, upgrade to Biblio Autocomplete 7.x-1.5.

Additionally there is a new permission “access biblio autocomplete” for accessing the search. You need to give this permission to users with write permissions on Biblio nodes.
