Vulnerability Overview

The Houzez theme for WordPress is vulnerable to privilege escalation in versions up to, and including, 2.7.1. This is due to improper assignment of privileges on user management/registration that allows users to supply their own role via the houzez_change_user_role and houzez_register_user_with_membership AJAX actions. This makes it possible for unauthenticated attackers to register as administrators on vulnerable sites.

Technical Analysis

REMEDIATION: Update to version 2.7.2, or a newer patched version --- IDENTIFIER: CWE-266 (Incorrect Privilege Assignment) A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.
