Descriptions

The Edwiser Bridge plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including,2.0.6. This is due to missing or incorrect nonce validation on the user_data_synchronization_initiater(), course_synchronization_initiater(), users_link_to_moodle_synchronization(), connection_test_initiater(), admin_menus(), and subscribe_handler() function. This makes it possible for unauthenticated attackers to perform unauthorized actions via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

El plugin Edwiser Bridge para WordPress es vulnerable a ataques de tipo Cross-Site Request Forgery (CSRF) en versiones hasta la 2.0.6 inclusive. Esto es debido a la falta o incorrecta validación nonce en las funciones "user_data_synchronization_initiater()", "course_synchronization_initiater()", "users_link_to_moodle_synchronization()", "connection_test_initiater()", "admin_menus()" y "subscribe_handler()". Esto hace posible que atacantes no autenticados realicen acciones no autorizadas a través de una solicitud manipulada concedida y puedan engañar a un administrador del sitio para que realice una acción como hacer clic en un enlace.
