[IT-SecurityNotifies] [Security-news] SA-CONTRIB-2010-036 - Views - multiple vulnerabilities

[security-news AT drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2010-036
  * Project: Views (third-party module)
  * Version: 5.x, 6.x
  * Date: 2010-April-7
  * Security risk: Critical
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting (XSS), arbitrary code execution

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

The Views module provides a flexible method for Drupal site designers to
control how lists of content are presented. Views accepts parameters in the
URL and uses them in an AJAX callback. The values were not filtered, thus
allowing injection of JavaScript code via the AJAX response. A user tricked
into visiting a crafted URL could be exposed to arbitrary script or HTML
injected into the page. In addition, the Views module does not properly
sanitize file descriptions when displaying them in a view, thus the the file
desciptions may be used to inject arbitrary script or HTML. Such cross site
scripting [1] (XSS) attacks may lead to a malicious user gaining full
administrative access. These vulnerabilities affect only the Drupal 6
version. The file description vulnerability is mitigated by the fact that the
attacker must have permission to upload files. In both the Drupal 5 and
Drupal 6 versions, users with permission to 'administer views' can execute
arbitrary PHP code using the views import feature. An additional check for
the permission 'use PHP for block visibility' has been added to insure that
the site administrator has already granted users of the import functionality
the permission to execute PHP.
-------- VERSIONS AFFECTED  
---------------------------------------------------

  * Versions of Views for Drupal 6.x prior to 6.x-2.9
  * Versions of Views for Drupal 5.x prior to 5.x-1.7
