      "value": "The clustered setup of Apache MXNet allows users to specify which IP address and port the scheduler will listen on via the DMLC_PS_ROOT_URI and DMLC_PS_ROOT_PORT env variables. In versions older than 1.0.0, however, the MXNet framework will listen on 0.0.0.0 rather than user specified DMLC_PS_ROOT_URI once a scheduler node is initialized. This exposes the instance running MXNet to any attackers reachable via the interface they didn't expect to be listening on. For example: If a user wants to run a clustered setup locally, they may specify to run on 127.0.0.1. But since MXNet will listen on 0.0.0.0, it makes the port accessible on all network interfaces."

      "value": "La instalaci\u00f3n en cl\u00fasters de Apache MXNet permite que los usuarios especifiquen en qu\u00e9 direcci\u00f3n y puerto IP va a escuchar el scheduler mediante las variables de entorno DMLC_PS_ROOT_URI y DMLC_PS_ROOT_PORT. En las versiones anteriores a la 1.0.0, sin embargo, el framework MXNet escuchar\u00e1 en 0.0.0.0 en lugar del DMLC_PS_ROOT_URI especificado por el usuario una vez se ha inicializado un nodo scheduler. Esto expone la instancia que est\u00e1 ejecutando MXNet a cualquier atacante y la vuelve alcanzable mediante la interfaz que no esperaban que estuviese escuchando. Por ejemplo: si un usuario quiere ejecutar localmente una instalaci\u00f3n en cl\u00fasters, puede especificar que se ejecute en 127.0.0.1. Pero, debido a que MXNet escuchar\u00e1 en 0.0.0.0, hace que el puerto sea accesible en todas las interfaces de red."
