2.4.10 (2013-02-19)

Overview

Security: Undefined $allowed_actions overrides parent definitions
API: More restrictive $allowed_actions checks for Controller when used with Extension

Details

Security: Undefined `$allowed_actions` overrides parent definitions

Severity: Important

Description: Controller (and subclasses) failed to enforce $allowed_action restrictions on parent classes if a child class didn't have it explicitly defined.

Impact: Depends on the used controller code. For any method with public visibility, the flaw can expose the return value of the method (unless it fails due to wrong arguments). It can also lead to unauthorized or unintended execution of logic, e.g. modifying the state of a database record.

Fix: Apply the 2.4.10 update. In addition, we strongly recommend to define $allowed_actions on all controller classes to ensure the intentions are clearly communicated.

API: More restrictive `$allowed_actions` checks for `Controller` when used with `Extension`

Controllers which are extended with $allowed_actions (through an Extension) now deny access to methods defined on the controller, unless this class also has them in its own $allowed_actions definition.
