| Titel: | [Drupal] Security announcements: Arbitrary code execution |
------------DRUPAL CORE - ARBITRARY CODE EXECUTION------------ * Advisory ID: DRUPAL-SA-2007-005 * Project: Drupal core * Version: 4.7.x, 5.x * Date: 2007-Jan-29 * Security risk: Highly critical * Exploitable from: Remote * Vulnerability: Arbitrary code execution ------------DESCRIPTION------------ Previews on comments were not passed through normal form validation routines, enabling users with the 'post comments' permission and access to more than one input filter to execute arbitrary code.
