Prior to 0.16.1, EPyT-Flow\u2019s REST API parses attacker-controlled JSON request bodies using a custom deserializer (my_load_from_json) that supports a type field. When type is present, the deserializer dynamically imports an attacker-specified module/class and instantiates it with attacker-supplied arguments. This allows invoking dangerous classes such as subprocess.Popen, which can lead to OS command execution during JSON parsing. This also affects the loading of JSON files. This vulnerability is fixed in 0.16.1."}, {"lang": "es", "value": "EPyT-Flow es un paquete de Python dise\u00f1ado para la f\u00e1cil generaci\u00f3n de datos de escenarios hidr\u00e1ulicos y de calidad del agua de redes de distribuci\u00f3n de agua. Antes de la versi\u00f3n 0.16.1, la API REST de EPyT-Flow analiza cuerpos de solicitud JSON controlados por el atacante utilizando un deserializador personalizado (my_load_from_json) que soporta un campo type. Cuando type est\u00e1 presente, el deserializador importa din\u00e1micamente un m\u00f3dulo/clase especificado por el atacante y lo instancia con argumentos proporcionados por el atacante.
