AusCERT Security Bulletin Summary
---------------------------------
Product: FileField (third-party module)
Views (third-party module)
Publisher: Drupal
Operating System: UNIX variants (UNIX, Linux, OSX)
Windows
Impact/Access: Cross-site Scripting -- Remote with User Interaction

Resolution: Patch/Upgrade
Original Bulletin:
http://drupal.org/node/829808
http://drupal.org/node/829840
Comment: This bulletin contains two (2) Drupal security advisories.
- --------------------------BEGIN INCLUDED TEXT--------------------
* Advisory ID: DRUPAL-SA-CONTRIB-2010-066
* Project: FileField (third-party module)
* Version: 5.x, 6.x
* Date: 2010-June-16
* Security risk: Moderately critical
* Exploitable from: Remote
* Vulnerability: Cross Site Scripting
- -------- DESCRIPTION
- ---------------------------------------------------------
FileField module integrates with the Content Construction Kit to provide a
file upload field. It also integrates with the Views and Token modules. The
module does not sanitize some of the user-supplied data before displaying it
(for Drupal 6.x-3.x only), or before adding it to tokens (both 5.x-2.x and
6.x-3.x), leading to a Cross Site Scripting (XSS [1]) vulnerability that may
lead to a malicious user gaining full administrative access. This
vulnerability is mitigated by the fact that the attacker must be able to
create or edit content with a FileField, and the site administrator must have
configured a vulnerable display format ('Path to File' or 'URL to File') or
be using token containing the filename, filepath, or description.
- -------- VERSIONS AFFECTED
- ---------------------------------------------------
* FileField module for Drupal 5.x versions prior to 5.x-2.5
* FileField module for Drupal 6.x versions prior to 6.x-3.4
Drupal core is not affected. If you do not use the contributed FileField [2]
module, there is nothing you need to do.
- -------- SOLUTION
- ------------------------------------------------------------
Install the latest version:
* If you use the FileField module for Drupal 5.x upgrade to FileField
5.x-2.5 [3]
* If you use the FileField module for Drupal 6.x upgrade to FileField
6.x-3.4 [4]
See also the FileField project page [5].

* Advisory ID: DRUPAL-SA-CONTRIB-2010-067
* Project: Views (third-party module)
* Version: 5.x, 6.x
* Date: 2010-June-16
* Security risk: Less critical
* Exploitable from: Remote
* Vulnerability: Multiple vulnerabilities
- -------- DESCRIPTION
- ---------------------------------------------------------
The Views module provides a flexible method for Drupal site designers to
control how lists and tables of content are presented.
- -------- CROSS SITE REQUEST FORGERY (CSRF)
- -----------------------------------
The Views UI module, which is included with Views, can be used to
enable/disable Views by following a link to a particular page (e.g.
admin/build/views/disable/frontpage). As no protections, such as form tokens,
are in place to prevent forged requests to these pages, the feature is
vulnerable to a Cross Site Request Forgery (CSRF [1]) that would allow an
attacker to enable/disable all Views on a site. Mitigating factors: If Views
UI module is disabled Views will no longer be affected by this vulnerability.
This issue affects Views for Drupal 5 and Drupal 6.
- -------- CROSS SITE SCRIPTING (XSS)
- ------------------------------------------
Under certain circumstances, Views could display URLs or aggregator feed
titles without escaping, resulting in a Cross Site Scripting (XSS [2])
vulnerability. An attacker could exploit this to gain full administrative
access. This issue affects Views for Drupal 6 only.
- -------- VERSIONS AFFECTED
- ---------------------------------------------------
* Views module for Drupal 5.x versions prior to 5.x-1.8
* Views module for Drupal 6.x versions prior to 6.x-2.11
Drupal core is not affected. If you do not use the contributed Views [3]
module, there is nothing you need to do.
- -------- SOLUTION
- ------------------------------------------------------------
Install the latest version:
* If you use the Views module for Drupal 5.x upgrade to Views 5.x-1.8 [4]
* If you use the Views module for Drupal 6.x upgrade to Views 6.x-2.11 [5]
See also the Views project page [6].
- -------- REPORTED BY
- ---------------------------------------------------------
* The Cross Site Request Forgery (CSRF) vulnerability was reported by Martin
Barbella (mbarbella [7]).
* The Cross Site Scripting (XSS) vulnerabilities were reported by Earl Miles
(merlinofchaos [8]), module maintainer and Daniel Wehner (dereine [9]),
module co-maintainer
