Official description

The Donation Forms by Charitable plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 1.7.0.12 due to insufficient restriction on the 'update_core_user' function. This makes it possible for unauthenticated attackers to specify their user role by supplying the 'role' parameter during a registration.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Improper Privilege Management

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

How developers prevent this class of flaw

  • Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
  • Follow the principle of least privilege when assigning access rights to entities in a software system.
  • Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
