Vulnerability Overview

The W3 Total Cache plugin before 0.9.4.1 for WordPress does not properly handle empty nonces, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks and hijack the authentication of administrators for requests that change the mobile site redirect URI via the mobile_groups[*][redirect] parameter and an empty _wpnonce parameter in the w3tc_mobile page to wp-admin/admin.php.

Technical Analysis

REMEDIATION: Update to version 0.9.4.1, 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.
