Sin embargo, el middleware ABAC evaluaba la ruta de solicitud original incluyendo la barra final. Si la b\u00fasqueda de ruta de ABAC no encontraba una ruta coincidente con sufijo de barra, la solicitud se pasaba adelante y el router entonces eliminaba la barra y ejecutaba el gestor protegido sin la decisi\u00f3n de autorizaci\u00f3n ABAC prevista y sin los filtros de consulta ABAC esperados.\n\nUn atacante de red no autenticado o no autorizado podr\u00eda a\u00f1adir una barra final a rutas API protegidas para alcanzar gestores que deber\u00edan haber sido denegados por la pol\u00edtica ABAC. Dependiendo del componente expuesto, el m\u00e9todo HTTP y la pol\u00edtica desplegada, esto podr\u00eda permitir operaciones no autorizadas de lectura, creaci\u00f3n, actualizaci\u00f3n, eliminaci\u00f3n o carga.\n\nEl problema afecta a las implementaciones con ABAC habilitado de servicios que utilizan el router compartido y el middleware ABAC, incluyendo AAS Repository, Submodel Repository, AAS Registry, Submodel Registry, Concept Description Repository, Discovery, carga de entorno AAS y servicios relacionados.
