Drupal core is not affected. If you do not use the contributed elFinder file manager [4] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the elfinder module 0.x for Drupal 6.x, upgrade to elfinder 6.x-0.8 [5] (requires elFinder 1.2 [6] library) * If you use the elfinder module 0.x for Drupal 7.x, upgrade to elfinder 7.x-0.8 [7] (requires elFinder 1.2 [8] library) Also see the elFinder file manager [9] project page. -------- REPORTED BY --------------------------------------------------------- * Greg Knaddison [10] of the Drupal Security Team -------- FIXED BY ------------------------------------------------------------ * Alexey Sukhotin [11] the module maintainer * Greg Knaddison [12] of the Drupal Security Team * Fox [13] of the Drupal Security Team -------- COORDINATED BY ------------------------------------------------------ * Fox [14] of the Drupal Security Team * David Stoline [15] 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 [16].
