Vulnerability Overview

The Spin Wheel plugin for WordPress is vulnerable to client-side prize manipulation in all versions up to, and including, 2.1.0. This is due to the plugin trusting client-supplied prize selection data without server-side validation or randomization. This makes it possible for unauthenticated attackers to manipulate which prize they win by modifying the 'prize_index' parameter sent to the server, allowing them to always select the most valuable prizes.

Technical Analysis

REMEDIATION: Update to version 2.1.1, or a newer patched version --- IDENTIFIER: CWE-602 (Client-Side Enforcement of Server-Side Security) The product is composed of a server that relies on the client to implement a mechanism that is intended to protect the server.
