[IT-SecNots] [Security-news] SA-CONTRIB-2011-046

[security-news AT drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2011-046
  * Project: Echo [1] (third-party module)
  * Version: 6.x, 7.x, 8.x
  * Date: 2011-October-05
  * Security risk: Critical [2]
  * Exploitable from: Remote
  * Vulnerability: Multiple vulnerabilities

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

The Echo module generates a fully-themed Drupal page, returning the rendered
page as a text string and allowing other modules to style an HTML message as
if it had been generated by the live website.

The module does not properly sanitize user-supplied content, resulting in a
Cross-Site Scripting (XSS [3]) vulnerability. Additionally, the module allows
arbitrary content passed via the URL to be embedded on the site, rendering
the site vulnerable to phishing [4] exploits.

-------- VERSIONS AFFECTED  
---------------------------------------------------

  * Echo 6.x-1.x versions prior to 6.x-1.7 [5].
  * Echo 7.x-1.x versions prior to 7.x-1.7 [6].
  * Echo 8.x-1.x versions prior to 8.x-1.7 [7].

Drupal core is not affected. If you do not use the contributed Echo [8]
module, there is nothing you need to do.

-------- SOLUTION  
------------------------------------------------------------

Install the latest version:

  * If you use the Echo module for Drupal 6.x, upgrade to Echo 6.x-1.7 [9].
  * If you use the Echo module for Drupal 7.x, upgrade to Echo 7.x-1.7 [10].
  * If you use the Echo module for Drupal 8.x, upgrade to Echo 8.x-1.7 [11].
