СреднийУровень 1Автоматическаяlinux
Описание
The root user can execute any command on the system and could be fooled into executing programs unintentionally if the PATH is not set correctly.
Как проверяется
Метод проверки: Команда оболочки
shell
alt0() { o=$(bash -c '#!/usr/bin/env bash
{
l_output2=""
l_pmask="0022"

compliant
Как исправляется
Метод исправления: Рекомендация или патч инфраструктуры
Correct or justify any: • Locations that are not directories • Empty directories (::) • Trailing (:) • Current working directory (.) • Non root owned directories • Directories that less restrictive than mode 0755
