SA-CORE-2009-005 - Drupal core - Cross site scripting
by security-news＠drupal.org 30 Apr '09

30 Apr '09

* Advisory ID: DRUPAL-SA-CORE-2009-005 * Project: Drupal core * Version: 5.x, 6.x * Date: 2009-April-29 * Security risk: Moderately critical * Exploitable from: Remote * Vulnerability: Cross site scripting -------- DESCRIPTION --------------------------------------------------------- When outputting user-supplied data Drupal strips potentially dangerous HTML attributes and tags or escapes characters which have a special meaning in HTML. This output filtering secures the site against cross site scripting attacks via user input. Certain byte sequences that are valid in the UTF-8 specification are potentially dangerous when interpreted as UTF-7. Internet Explorer 6 and 7 may decode these characters as UTF-7 if they appear before the <meta http-equiv="Content-Type" /> tag that specifies the page content as UTF-8, despite the fact that Drupal also sends a real HTTP header specifying the content as UTF-8. This behaviour enables malicious users to insert and execute Javascript in the context of the website if site visitors are allowed to post content. Wikipedia has more information about cross site scripting [1] (XSS). In addition, Drupal core also has a very limited information disclosure vulnerability under very specific conditions. If a user is tricked into visiting the site via a specially crafted URL and then submits a form (such as the search box) from that page, the information in their form submission may be directed to a third-party site determined by the URL and thus disclosed to the third party. The third party site may then execute a CSRF [2] attack against the submitted form. This vulnerability is limited to forms present on the frontpage. The user login form is not vulnerable. -------- VERSIONS AFFECTED --------------------------------------------------- * Drupal 5.x before version 5.17. * Drupal 6.x before version 6.11. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you are running Drupal 6.x then upgrade to Drupal 6.11 [3]. * If you are running Drupal 5.x then upgrade to Drupal 5.17 [4]. If you are unable to upgrade immediately, you can apply a patch to secure your installation until you are able to do a proper upgrade. Theses patches fix the security vulnerability, but does not contain other fixes which were released in Drupal 5.17 or Drupal 6.11. * To patch Drupal 6.10 use SA-CORE-2009-005-6.10.patch [5]. * To patch Drupal 5.16 use SA-CORE-2009-005-5.16.patch [6]. As an alternate solution if you are unable to upgrade immediately, you can alter your page template following the pattern in the core changes. Open your theme's main page.tpl.php file as well as any other page templates like page-node.tpl.php or page-front.tpl.php and move the line that is printing $head (<?php print $head ?>) above line with the <title> tag, so that it is the first item after the <head>. -------- REPORTED BY --------------------------------------------------------- The UTF-7 XSS issue was reported by pod.Edge. The information disclosure vulnerability was reported by Moritz Naumann [7]. -------- FIXED BY ------------------------------------------------------------ The Drupal security team -------- CONTACT ------------------------------------------------------------- The security team for Drupal can be reached at security at drupal.org or via the form at http://drupal.org/contact.

SA-CONTRIB-2009-019 - Localization client - Cross site scripting
by security-news＠drupal.org 15 Apr '09

15 Apr '09

* Advisory ID: DRUPAL-SA-CONTRIB-2009-019 * Project: Localization client (third-party module) * Versions: 5.x, 6.x * Date: 2009-April-15 * Security risk: Moderately critical * Exploitable from: Remote * Vulnerability: Cross-site scripting (XSS) -------- DESCRIPTION --------------------------------------------------------- The Localization client module allows you to translate the interface of your Drupal site from within each page as you go. When displaying translatable strings and their completed translations, the module does not escape the data. If used to translate the Drupal core interface, this is not a problem, since no user input is involved. However, when used with modules such as the Internationalization module suite or Views, user provided data is translated, making the module vulnerable to cross site scripting [1] (XSS). This enables malicious users to insert arbitrary HTML and scripts into certain pages. Such an attack against sufficiently privileged users may lead to adminstrator access to the site. -------- VERSIONS AFFECTED --------------------------------------------------- * Versions of Localization client for Drupal 5.x prior to 5.x-1.2 * Versions of Localization client for Drupal 6.x prior to 6.x-1.7 Drupal core is not affected. If you do not use the Localization client module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version. * If you use Localization client on Drupal 5, upgrade to Localization client 5.x-1.2 [2] * If you use Localization client on Drupal 6, upgrade to Localization client 6.x-1.7 [3] -------- REPORTED BY --------------------------------------------------------- Grégoire Moreau -------- FIXED BY ------------------------------------------------------------ Roger Lopez, Alexander Hass, Bálint Csuthy, Jose A. Reyero and Gábor Hojtsy -------- CONTACT ------------------------------------------------------------- The security contact for Drupal can be reached at security at drupal.org or via the form at http://drupal.org/contact [4] and by selecting the security issues category.
