Descriptions

The WP 2FA – Two-factor authentication for WordPress plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.5.0. This is due to missing or incorrect nonce validation on the send_backup_codes_email function. This makes it possible for unauthenticated attackers to send emails with arbitrary content to registered users via a forged request granted they can trick a site administrator or other registered user into performing an action such as clicking on a link. While a nonce check is present, it is only executed if a nonce is set. By omitting a nonce from the request, the check can be bypassed.

El complemento WP 2FA – Two-factor authentication for WordPress para WordPress es vulnerable a Cross-Site Request Forgery en todas las versiones hasta la 2.5.0 incluida. Esto se debe a una validación nonce faltante o incorrecta en la función send_backup_codes_email. Esto hace posible que atacantes no autenticados envíen correos electrónicos con contenido arbitrario a usuarios registrados a través de una solicitud falsificada, siempre que puedan engañar a un administrador del sitio u otro usuario registrado para que realice una acción como hacer clic en un enlace. Mientras esté presente una verificación de nonce, solo se ejecuta si se establece un nonce. Al omitir un nonce de la solicitud, se puede omitir la verificación.
