This way, an attacker can, for example, fake a remember-me token, assume the identity of the global system administrator and request non-public content from the search service without ever providing any proper authentication. This problem is fixed in Opencast 7.6 and Opencast 8.1"},{"lang":"es","value":"En Opencast versiones anteriores a 7.6 y 8.1, usando una cookie remember-me con un nombre de usuario arbitrario puede causar que Opencast asuma una autenticación apropiada para ese usuario, inclusive si la cookie remember-me era incorrecta, dado que el endpoint atacado también permite el acceso anónimo. De esta forma, un atacante puede, por ejemplo, falsificar un token de remember-me, asumir la identidad del administrador del sistema global y solicitar contenido no público desde el servicio de búsqueda sin proporcionar una autenticación adecuada.
