What the vulnerability does
01Description
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.
Explanation of Vulnerability in Simple Terms
02Summary
Word 2 Cash versions 0.9.2 and earlier are vulnerable to cross-site request forgery (CSRF) attacks. An attacker can craft a malicious webpage that, when visited by a logged-in site administrator, performs unwanted actions on the site without the administrator's knowledge or consent. The attack requires the victim to visit the attacker's page while authenticated.
