El sistema no valida las extensiones de archivo, los tipos MIME o el contenido del archivo durante las cargas. Como resultado, scripts maliciosos como web shells basadas en Node.js pueden ser cargados y almacenados persistentemente en el servidor. Estas shells exponen puntos finales HTTP capaces de ejecutar comandos arbitrarios si se activan. La shell cargada no se ejecuta autom\u00e1ticamente, pero su presencia permite una explotaci\u00f3n futura a trav\u00e9s de un error del administrador o vulnerabilidades encadenadas.
