19 Dec '12

View online: http://drupal.org/node/1870550 * Advisory ID: DRUPAL-SA-CONTRIB-2012-174 * Project: Context [1] (third-party module) * Version: 6.x, 7.x * Date: 2012-12-19 * Security risk: Less critical [2] * Exploitable from: Remote * Vulnerability: Information Disclosure -------- DESCRIPTION --------------------------------------------------------- Context has functionality that renders block content for use with its inline editor. When these requests are made the context module does not sufficiently ensure that users have access to the block. A malicious user could send a specially crafted request and get access to block content they should not be able to see. This vulnerability is mitigated by the fact that an attacker must know the identifiers for the block containing sensitive information and that the block's code must render that sensitive information when requested by a user without privileges to see this information. -------- CVE IDENTIFIER(S) ISSUED -------------------------------------------- * /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./ -------- VERSIONS AFFECTED --------------------------------------------------- * Context 6.x-3.x versions prior to 6.x-3.1. * Context 7.x-3.x versions prior to 7.x-3.0-beta6. Drupal core is not affected. If you do not use the contributed Context [4] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the Context module for Drupal 6.x, upgrade to Context 6.x-3.1 [5] * If you use the Context module for Drupal 7.x, upgrade to Context 7.x-3.0-beta6 [6] Also see the Context [7] project page. -------- REPORTED BY --------------------------------------------------------- * Fox (hefox) [8] of the Drupal Security Team -------- FIXED BY ------------------------------------------------------------ * Fox (hefox) [9] the module maintainer * tekante [10] the module maintainer -------- COORDINATED BY ------------------------------------------------------ * Fox (hefox) [11] of the Drupal Security Team -------- CONTACT AND MORE INFORMATION ---------------------------------------- The Drupal security team can be reached at security at drupal.org or via the contact form at http://drupal.org/contact [12].

SA-CORE-2012-004 - Drupal core - Multiple vulnerabilities
by security-news＠drupal.org 19 Dec '12

19 Dec '12

View online: http://drupal.org/SA-CORE-2012-004 * Advisory ID: DRUPAL-SA-CORE-2012-004 * Project: Drupal core [1] * Version: 6.x, 7.x * Date: 2012-December-19 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Access bypass, Arbitrary PHP code execution -------- DESCRIPTION --------------------------------------------------------- Multiple vulnerabilities were fixed in the supported Drupal core versions 6 and 7. .... Access bypass (User module search - Drupal 6 and 7) A vulnerability was identified that allows blocked users to appear in user search results, even when the search results are viewed by unprivileged users. This vulnerability is mitigated by the fact that the default Drupal core user search results only display usernames (and disclosure of usernames is not considered a security vulnerability [3]). However, since modules or themes may override the search results to display more information from each user's profile, this could result in additional information about blocked users being disclosed on some sites. CVE: Requested. .... Access bypass (Upload module - Drupal 6) A vulnerability was identified that allows information about uploaded files to be displayed in RSS feeds and search results to users that do not have the "view uploaded files" permission. This issue affects Drupal 6 only. CVE: Requested. .... Arbitrary PHP code execution (File upload modules - Drupal 6 and 7) Drupal core's file upload feature blocks the upload of many files that can be executed on the server by munging the filename. A malicious user could name a file in a manner that bypasses this munging of the filename in Drupal's input validation. This vulnerability is mitigated by several factors: The attacker would need the permission to upload a file to the server. Certain combinations of PHP and filesystems are not vulnerable to this issue, though we did not perform an exhaustive review of the supported PHP versions. Finally: the server would need to allow execution of files in the uploads directory. Drupal core has protected against this with a .htaccess file protection in place from SA-2006-006 - Drupal Core - Execution of arbitrary files in certain Apache configurations [4]. Users of IIS should consider updating their web.config [5]. Users of Nginx should confirm that only the index.php and other known good scripts are executable. Users of other webservers should review their configuration to ensure the goals are achieved in some other way. CVE: Requested. -------- CVE IDENTIFIER(S) ISSUED -------------------------------------------- * /A CVE identifier [6] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./ -------- VERSIONS AFFECTED --------------------------------------------------- * Drupal core 6.x versions prior to 6.27. * Drupal core 7.x versions prior to 7.18. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use Drupal 6.x, upgrade to Drupal core 6.27 [7]. * If you use Drupal 7.x, upgrade to Drupal core 7.18 [8]. Also see the Drupal core [9] project page. -------- REPORTED BY --------------------------------------------------------- * The access bypass issue in the User module search results was reported by Derek Wright [10] of the Drupal Security Team. * The access bypass issue in the Drupal 6 Upload module was reported by Simon Rycroft [11], and by Damien Tournoud [12] of the Drupal Security Team. * The arbitrary code execution issue was reported by Amit Asaravala [13]. -------- FIXED BY ------------------------------------------------------------ * The access bypass issue in the User module search results was fixed by Derek Wright [14], Ivo Van Geertruyen [15], Peter Wolanin [16], and David Rothstein [17], all members of the Drupal Security Team. * The access bypass issue in the Drupal 6 Upload module was fixed by Michaël Dupont [18], and by Fox [19] and David Rothstein [20] of the Drupal Security Team. * The arbitrary code execution issue was fixed by Nathan Haug [21] and Justin Klein-Keane [22], and by John Morahan [23] and Greg Knaddison [24] of the Drupal Security team. -------- COORDINATED BY ------------------------------------------------------ * Jeremy Thorson [25] QA/Testing infrastructure * Ben Jeavons [26] of the Drupal Security Team * David Rothstein [27] of the Drupal Security Team * Gábor Hojtsy [28] of the Drupal Security Team * Greg Knaddison [29] of the Drupal Security Team * Fox [30] of the Drupal Security Team -------- CONTACT AND MORE INFORMATION ---------------------------------------- The Drupal security team can be reached at security at drupal.org or via the contact form at http://drupal.org/contact [31].

SA-CONTRIB-2012-173 - Nodewords: Information disclosure
by security-news＠drupal.org 05 Dec '12

05 Dec '12

View online: http://drupal.org/node/1859282 * Advisory ID: DRUPAL-SA-CONTRIB-2012-173 * Project: Nodewords: D6 Meta Tags [1] (third-party module) * Version: 6.x * Date: 2012-December-05 * Security risk: Not critical [2] * Exploitable from: Remote * Vulnerability: Information Disclosure -------- DESCRIPTION --------------------------------------------------------- This module enables you to assign meta tags on Drupal 6 sites to aid with 3rd party search indexing and sharing on social networks. The module doesn't correctly filter node content when configured to automatically generate descriptions meta tags from the node text. This lack of filtering could allow some code, e.g. BBCode, to pass through unprocessed and potentially display private or otherwise secret information, links, file paths or other potentially sensitive details. The problem affects the normal 'description' meta tag along with the 'dc.description' and 'og:description' meta tags, all of which used the same logic. This vulnerability is mitigated by the fact that it is unlikely that sensitive content would be within the extracted portion. -------- CVE IDENTIFIER(S) ISSUED -------------------------------------------- * /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./ -------- VERSIONS AFFECTED --------------------------------------------------- * Nodewords 6.x-1.x versions prior to 6.x-1.14. Drupal core is not affected. If you do not use the contributed Nodewords: D6 Meta Tags [4] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the Nodewords module for Drupal 6.x, upgrade to Nodewords 6.x-1.14 [5]. Also see the Nodewords: D6 Meta Tags [6] project page. -------- REPORTED BY --------------------------------------------------------- * Andrey Tretyakov [7] * asb [8] -------- FIXED BY ------------------------------------------------------------ * Damien McKenna [9] the module maintainer. -------- COORDINATED BY ------------------------------------------------------ * Chris Hales [10] of the Drupal Security Team * Greg Knaddison [11] of the Drupal Security Team -------- CONTACT AND MORE INFORMATION ---------------------------------------- The Drupal security team can be reached at security at drupal.org or via the contact form at http://drupal.org/contact [12].
