The following flaw was found in Drupal: Drupal core and contributed modules frequently use a "destination" query string parameter in URLs to redirect users to a new destination after completing an action on the current page. Under certain circumstances, malicious users can use this parameter to construct a URL that will trick users into being redirected to a 3rd party website, thereby exposing the users to potential social engineering attacks. In addition, several URL-related API functions in Drupal 6 and 7 can be tricked into passing through external URLs when not intending to, potentially leading to additional open redirect vulnerabilities. This vulnerability is mitigated by the fact that many common uses of the "destination" parameter are not susceptible to the attack. However, all confirmation forms built using Drupal 7's form API are vulnerable via the Cancel action that appears at the bottom of the form, and some Drupal 6 confirmation forms are vulnerable too.
