# 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.
