Descriptions
OpenBSD 6.6, in a non-default configuration where S/Key or YubiKey authentication is enabled, allows local users to become root by leveraging membership in the auth group. This occurs because root's file can be written to /etc/skey or /var/db/yubikey, and need not be owned by root.
OpenBSD versión 6.6, en una configuración no predeterminada donde la autenticación S/Key o YubiKey está habilitada, permite a usuarios locales convertirse a root mediante el aprovechamiento de la membresía en el grupo de autenticación. Esto ocurre porque el archivo root puede ser escrito en /etc/skey o /var/db/yubikey, y no es necesario que sea propiedad de root.
