Vulnerability Overview

The Big Store plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.9.3. This is due to missing or incorrect nonce validation on the default_home and th_activeplugin functions. This makes it possible for unauthenticated attackers to activate arbitrary plugins via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.

Technical Analysis

REMEDIATION: Update to version 1.9.4, or a newer patched version --- IDENTIFIER: CWE-352 (Cross-Site Request Forgery (CSRF)) The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
