View online: https://drupal.org/node/2081637 * Advisory ID: DRUPAL-SA-CONTRIB-2013-073 * Project: Make Meeting Scheduler [1] (third-party module) * Version: 6.x * Date: 2013-September-04 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Access bypass -------- DESCRIPTION --------------------------------------------------------- This module enables you to create polls accessible by an url with hash (e.g. example.com/makemeeting/sn9028xh3398) so that anonymous users can view and vote on the poll. The module didn't sufficiently check access when a poll is accessed directly via its node url (e.g. node/123). Note: a user with the hashed url can still access and vote on the poll as that is the intention of the module. -------- CVE IDENTIFIER(S) ISSUED -------------------------------------------- * /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./ -------- VERSIONS AFFECTED --------------------------------------------------- * Make Meeting Scheduler 6.x-1.x versions prior to 6.x-1.3. Drupal core is not affected. If you do not use the contributed Make Meeting Scheduler [4] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the Make Meeting Scheduler module for Drupal 6.x, upgrade to Make Meeting Scheduler module 6.x-1.3 [5] Also see the Make Meeting Scheduler [6] project page. -------- REPORTED BY --------------------------------------------------------- * rhatto [7] -------- FIXED BY ------------------------------------------------------------ * rhatto [8] * SebCorbin [9] the module maintainer -------- COORDINATED BY ------------------------------------------------------ * Greg Knaddison [10] 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 [11].
