Key facts

Description

The Word 2 Cash plugin for WordPress is vulnerable to Cross-Site Request Forgery leading to Stored Cross-Site Scripting in versions up to and including 0.9.2. This is due to the complete absence of nonce verification on the settings save handler in the w2c_admin() function, combined with missing input sanitization before storage and missing output escaping when rendering the stored value. The w2c-definitions POST parameter is saved raw via update_option() and later echoed without escaping inside a <textarea> element. This makes it possible for unauthenticated attackers to forge a request on behalf of a logged-in administrator, storing arbitrary JavaScript payloads that execute in the WordPress admin panel whenever the settings page is visited.
