Drupal security advisory DRUPAL-SA-2005-001
----------------------------------------------------------------------------
Advisory ID: DRUPAL-SA-2005-001
Date: 2005-jun-01
Security risk: highly critical
Impact: system access
Where: from remote
Vulnerability: privilege escalation
----------------------------------------------------------------------------
Description
-----------
The Drupal Security Team has found that the privilege system of Drupal can=
=20
be circumvented in a very special case because an input check is not=20
implemented properly.
Versions affected
-----------------
Drupal 4.4.0, 4.4.1, 4.4.2
Drupal 4.5.0, 4.5.1, 4.5.2
Drupal 4.6.0
Impact
------
If public registration is allowed then it is possible for an attacker
to obtain additional user roles. As a result, an attacker could grant=20
himself administration privileges.
Solution
--------
Either upgrade or disable public registration: =20
- If you are running Drupal 4.4.x, then upgrade to Drupal 4.4.3.
- If you are running Drupal 4.5.2, then upgrade to Drupal 4.5.3.
- If you are running Drupal 4.6.0, then upgrade to Drupal 4.6.1.
- If you cannot upgrade immediately, you can secure your site by=20
disabling the public registration of Drupal accounts from Drupal's user
administration screen. Log-in as an administrator, go to "administer >>=
=20
users >> configure" and set the "Public registrations" option to "Only=20
site administrators can create new user accounts".
