La plataforma funciona con PHP como lenguaje frontend y usa scripts de shell para ejecutar acciones del sistema. PHP ejecuta script de shell por medio del peligroso comando exec. Esta funci\u00f3n puede ser peligrosa si los argumentos pasados no son filtrados. Cada entrada de usuario en VestaCP que se utiliza como argumento es filtrada con la funci\u00f3n escapeshellarg. Esta funci\u00f3n proviene directamente de la biblioteca PHP y su descripci\u00f3n es la siguiente: \"escapeshellarg() agrega comillas simples alrededor de una cadena y cita/escapa a las comillas simples existentes permitiendo pasar una cadena directamente a una funci\u00f3n de shell y hacer que se trate como un \u00fanico argumento seguro\". Quiere decir, que si le da nombre de usuario, tendr\u00e1 \"Username\" como reemplazo. Esto opera bien y protege a usuarios de explotar esta funci\u00f3n exec peligrosa potencialmente.
