Ensure permissions on bootloader config are configured

中等級 1自動化ros

說明

The grub configuration file contains information on boot settings and passwords for unlocking boot options. The grub configuration is usually grub.cfg stored in /boot/grub/. The audit requires /boot/grub/grub.cfg owned by root:root with no group or other permissions. Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.

[ -e /boot/grub/grub.cfg ] || { echo '/boot/grub/grub.cfg not found'; exit 1; }
set -- $(stat -Lc '%a %u %g' /boot/grub/grub.cfg) || exit 1
m=$((8#$1)); [ $((m & ~8#0700)) -eq 0 ] || { echo "/boot/grub/grub.cfg mode $1 exceeds 0700"; exit 1; }
[ "$2" = 0 ] || { echo "/boot/grub/grub.cfg uid $2"; exit 1; }
case " 0 " in *" $3 "*) echo compliant ;; *) echo "/boot/grub/grub.cfg gid $3" ;; esac
