Descriptions

Moodle 2.9.x before 2.9.3 does not properly check the contact list before authorizing message transmission, which allows remote authenticated users to bypass intended access restrictions and conduct spam attacks via the messaging API.

Moodle 2.9.x en versiones anteriores a 2.9.3 no comprueba adecuadamente la lista de contactos antes de autorizar la transmisión del mensaje, lo que permite a usuarios remotos autenticados eludir las restricciones destinadas al acceso y llevar a cabo ataques de spam a través de la API messaging.
