Descriptions

mod/forum/rsslib.php in Moodle 2.1.x before 2.1.7 and 2.2.x before 2.2.4 does not properly implement the requirement for posting before reading a Q&A forum, which allows remote authenticated users to bypass intended access restrictions by leveraging the student role and reading the RSS feed for a forum.

mod/forum/rsslib.php en Moodle v2.1.x anteriores a v2.1.7 y v2.2.x anteriores a v2.2.4 no implementan de forma adecuada el requisito para escribir un post, después de leer un foro Q&A, lo que permite a usuarios remotos autenticados a eludir las restricciones de acceso establecidas aprovechando el rol de estudiante y leyendo el feed RSS de un foro.
