• Advisory ID: DRUPAL-SA-2006-006
  • Project: Drupal core
  • Date: 2006-May-24
  • Security risk: highly critical
  • Impact: Drupal core
  • Exploitable from: remote
  • Vulnerability: Execution of arbitrary files


Certain -- alas, typical -- configurations of Apache allows execution of
carefully named arbitrary scripts in the files directory. Drupal now will
attempt to automatically create a .htaccess file in your "files" directory
to protect you. This line references SA_2006_006 to lead Apache administrators to this announcement.

SetHandler Drupal_Security_Do_Not_Remove_See_SA_2006_006

Versions affected

- All Drupal versions before 4.6.7 and also Drupal 4.7.0.


If you are running Drupal 4.6.x then upgrade to Drupal 4.6.7.
If you are running Drupal 4.7.0 then upgrade to Drupal 4.7.1.
To patch Drupal 4.6.6 use the http://drupal.org/files/sa-2006-006/4.6.6.patch.
To patch Drupal 4.7.0 use the http://drupal.org/files/sa-2006-006/4.7.0.patch.
