3.0.6-rc1 (2013-08-08)

Overview

  • Security: Require ADMIN for ?flush=1 (stop denial of service attacks) (#1692)

Details

Security: Require ADMIN for ?flush=1

Flushing the various manifests (class, template, config) is performed through a GET parameter (flush=1). Since this action requires more server resources than normal requests, it can facilitate denial-of-service attacks.

To prevent this, main.php now checks and only allows the flush parameter in the following cases:

  • The environment is in "dev mode"
  • A user is logged in with ADMIN permissions
  • An error occurs during startup

This applies to both flush=1 and flush=all (technically we only check for the existence of any parameter value) but only through web requests made through main.php - CLI requests, or any other request that goes through a custom start up script will still process all flush requests as normal.

Thanks to Christopher Tombleson for reporting.

Upgrading

  • If you have created your own composite database fields, then you should amend the setValue() to allow the passing of an object (usually DataObject) as well as an array.
  • If you have provided your own startup scripts (ones that include core/Core.php) that can be accessed via a web request, you should ensure that you limit use of the flush parameter
  • Translation entity namespaces can no longer contain dots, since it conflicts with the YAML format.
  • Translation entities defined in templates now use their fully qualified entity name without dots. Before: BackLink_Button.ss.Back, after BackLink_Button_ss.Back. Please fix any custom language files or uses of those entities in custom code.
  • If using "Māori/Te Reo" (mi_NZ) as your CMS locale, please re-select it in admin/myprofile to ensure correct operation (it has changed its locale identifier)
