SA-CONTRIB-2010-099 - Views Bulk Operations - Access Bypass
Security advisories for contributed projects Drupal 6.x
Drupal Security Team - October 6, 2010 - 21:32
* Advisory ID: DRUPAL-SA-CONTRIB-2010-099
* Project: Views Bulk Operations (third-party module)
* Version: 6.x
* Date: 2010-October-6
* Security risk: Not critical
* Exploitable from: Remote
* Vulnerability: Access bypass
Description
Views Bulk Operations augments Views by allowing bulk operations to be executed
on the nodes and users displayed by a view. It does so by showing a checkbox in
front of each item, and adding a select box containing operations that can be
applied on the selected items.
In some circumstances, a malicious user could use Views Bulk Operation to cause
user 0 (the anonymous user) to be deleted. The effects of deleting user 0 vary
depending on the system configuration and the use of other contributed modules,
ranging from trivial errors to significant loss of functionality.
The risk is mitigated by the fact that a malicious user would need permission
to a view that lets him/her manage users through Views Bulk Operations in
order to exploit this vulnerability.
Versions affected
* Views Bulk Operations for Drupal 6 prior to 6.x-1.10
Drupal core is not affected. If you do not use the contributed Views Bulk
Operations module, there is nothing you need to do.
Solution
Install the latest version:
* If you use the Views Bulk Operations module for Drupal 6.x upgrade to
Views Bulk Operations 6.x-1.10
See also the Views Bulk Operations project page.
