This can be locked down a bit by using chroot to change the root directory to protect files outside of the Karaf install directory; it can be further locked down by defining a security manager policy that limits file system access to those directories beneath the Karaf home that are necessary for the system to run. However, this still allows anyone with ssh access to the Karaf process to read and write a large number of files as the Karaf process user."}, {"lang": "es", "value": "En Apache Karaf en versiones anteriores a la 4.2.0, si el servicio sshd en Karaf se deja activo para que un administrador pueda gestionar la instancia en ejecuci\u00f3n, cualquier usuario con derechos en la consola Karaf puede pivotar y leer/escribir cualquier archivo en el sistema de archivos al que el usuario del proceso Karaf tiene acceso. Esto puede bloquearse parcialmente empleando chroot para cambiar el directorio root para proteger archivos fuera del directorio de instalaci\u00f3n de Karaf; puede bloquearse a\u00fan m\u00e1s definiendo una pol\u00edtica de gesti\u00f3n de seguridad que limite el acceso del sistema de archivos a esos directorios en el inicio de Karaf que son necesarios para que el sistema se ejecute.
