Descriptions

The User registration & user profile WordPress plugin through 2.0 does not have CSRF check in some places, and is missing sanitisation as well as escaping, which could allow attackers to make logged-in admin add Stored XSS payloads via a CSRF attack.

El complemento de WordPress User registration & user profile hasta la versión 2.0 no tiene verificación CSRF en algunos lugares y le falta sanitizacióny escape, lo que podría permitir a los atacantes hacer que el administrador conectado agregue payloads XSS almacenadas a través de un ataque CSRF.

The UserPlus plugin for WordPress is vulnerable to Cross-Site Request Forgery. This is due to missing or incorrect nonce validation on the 'save' function. This makes it possible for unauthenticated attackers to modify plugin options, including injecting malicious JavaScript into the plugin options, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This also makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute via this functionality.
