During initialization of nodes, some configuration parameters are retrieved from management nodes. These parameters embed credentials whose integrity and confidentiality may be important to the security of the HPC configuration. Because these parameters are needed for initialization, there is no available mechanism to ensure access control on the management node, and a mitigation measure is normally put in place to prevent access to unprivileged users. It was discovered that this mitigation measure does not survive a reboot of diskful nodes. (Diskless nodes are not at risk.) The mistake lies in the cloudinit configuration: the iptables configuration should have been in the bootcmd instead of the runcmd section."}, {"lang": "es", "value": "Se descubri\u00f3 un problema en Atos Eviden SMC xScale antes de la versi\u00f3n 1.6.6.

Estos par\u00e1metros incorporan credenciales cuya integridad y confidencialidad pueden ser importantes para la seguridad de la configuraci\u00f3n de HPC. Debido a que estos par\u00e1metros son necesarios para la inicializaci\u00f3n, no hay ning\u00fan mecanismo disponible para garantizar el control de acceso en el nodo de administraci\u00f3n y normalmente se implementa una medida de mitigaci\u00f3n para evitar el acceso a usuarios sin privilegios.
