Vulnerability Overview

The FS Registration Password plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 1.0.1. This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account.

Technical Analysis

REMEDIATION: Update to version 2.0.1, or a newer patched version --- IDENTIFIER: CWE-639 (Authorization Bypass Through User-Controlled Key) The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
