[Security-news] SA-CONTRIB-2009-047 - Calendar - Cross Site Scripting

[security-news at drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2009-047
  * Project: Calendar (third-party module)
  * Version: 6.x
  * Date: 2009-July-29
  * Security risk: Moderately critical
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

The Calendar module enables Views module to display any Date module date
field as a calendar. The module does not properly escape user input when
displaying titles of content types that have Date fields. A user with
permission to create new content types (including via the Date module's Date
Tools sub-module) could attempt a cross site scripting [1] (XSS) attack,
leading to the user gaining full administrative access.
-------- VERSIONS AFFECTED  
---------------------------------------------------

  * Calendar for Drupal 6.x prior to 6.x-2.2

Drupal core is not affected. If you do not use the contributed Calendar
module, there is nothing you need to do.
-------- SOLUTION  
------------------------------------------------------------

Upgrade to the latest version:
  * If you use Calendar for Drupal 6.x upgrade to Calendar 6.x-2.2 [2]

See also the Calendar project page [3].
