SA-CONTRIB-2013-001 - Search API - Cross Site Scripting

By Drupal Security Team on 9 Jan 2013 at 15:51 UTC

Advisory ID: DRUPAL-SA-CONTRIB-2013-001
Project: Search API (third-party module)
Version: 7.x
Date: 2013-January-09
Security risk: Moderately critical
Exploitable from: Remote
Vulnerability: Cross Site Scripting

Description

This module enables you to build searches using a wide range of features, data sources and backends.

The module doesn't sufficiently sanitize user input when displaying errors in a view with certain backends, including the database backend. This enables attackers to create a Reflected Cross Site Scripting attack by manipulating the URL.
This is mitigated by the fact that the vulnerability only occurs with some backends (the Solr backend, e.g., is safe) and for certain common configurations of facets.
The module also doesn't sufficiently sanitize output field names in the admin view.
This is mitigated by the fact that an attacker would have to have the necessary permissions to change the field names of an indexed entity type.

CVE identifier(s) issued
