En el sitio de Drupal -el software libre usado en Kriptópolis para la gestión y publicación electrónica (o web) de sus contenidos- han sido publicadas ayer mismo las siguientes vulnerabilidades:

SA-CONTRIB-2013-001 - Search API - Cross Site Scripting
===========================================
View online: http://drupal.org/node/1884332
.
* Advisory ID: DRUPAL-SA-CONTRIB-2013-001
* Project: Search API [1] (third-party module)
* Version: 7.x
* Date: 2013-January-09
* Security risk: Moderately critical [2]
* 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.
.
[...]
.
-------- VERSIONS AFFECTED ---------------------------------------------------
.
* Search API 7.x-1.x versions prior to 7.x-1.4.
.
Drupal core is not affected. If you do not use the contributed Search API [4] module, there is nothing you need to do.

P.S.

...las actualizaciones de seguridad de Drupal, siempre hay que distinguir entre problemas del core y problemas de los módulos de terceras partes. Los del core obligan a actualizar todo el sistema sin excusas, mientras que los módulos ("third party modules" en los avisos) sólo se actualizan cuando resultan afectados los que estás utilizando en tu sitio.

admin dixit.
