En Nautobot 1.x y 2.0.x anteriores a 1.6.7 y 2.0.6, se utilizan las URL `/files/get/?name=...` y `/files/download/?name=...` para proporcionar acceso de administrador a los archivos que se han cargado como parte de una solicitud de ejecuci\u00f3n para un trabajo que tiene entradas FileVar. En condiciones normales de funcionamiento, estos archivos son ef\u00edmeros y se eliminan una vez que se ejecuta el trabajo en cuesti\u00f3n. En la implementaci\u00f3n predeterminada utilizada en Nautobot, proporcionada por `django-db-file-storage`, estas URL no requieren de forma predeterminada ninguna autenticaci\u00f3n de usuario para acceder; en su lugar, deber\u00edan restringirse \u00fanicamente a los usuarios que tengan permisos para ver las instancias del modelo `FileProxy` de Nautobot. Tenga en cuenta que no se proporciona ning\u00fan mecanismo de URL para enumerar o recorrer los valores de \"nombre\" de archivos disponibles, por lo que en la pr\u00e1ctica un usuario no autenticado tendr\u00eda que adivinar nombres para descubrir archivos arbitrarios para descargar, pero si un usuario conoce el nombre del archivo/valor de ruta, pueden acceder a \u00e9l sin autenticarse, por lo que consideramos esto una vulnerabilidad.
