      "value": "In Opencast before 7.6 and 8.1, using a remember-me cookie with an arbitrary username can cause Opencast to assume proper authentication for that user even if the remember-me cookie was incorrect given that the attacked endpoint also allows anonymous access. 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"

      "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 autenticaci\u00f3n apropiada para ese usuario, inclusive si la cookie remember-me era incorrecta, dado que el endpoint atacado tambi\u00e9n permite el acceso an\u00f3nimo. 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 p\u00fablico desde el servicio de b\u00fasqueda sin proporcionar una autenticaci\u00f3n adecuada. Este problema se corrigi\u00f3 en Opencast versi\u00f3n 7.6 y Opencast versi\u00f3n 8.1."
