* 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 ------------------------------------------------------------

* 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].
