Ensure default path does not include current working directory

СредњаНиво 1Аутоматскаaix

Опис

This change removes any "." or "::" entries from /etc/environment. If a "." or "::" is present the current working directory is included in the default search path. Any "." and "::" will be removed from /etc/environment. This means that any harmful programs placed in common PATH locations, would never be automatically executed. All directories must be explicitly defined within the PATH variable. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.

Како се проверава

Метод провере: Команда љуске

shell

command -v grep >/dev/null 2>&1 || exit 1; [ -r /etc/environment ] || exit 1; out=$( { grep "^PATH=" /etc/environment | sed "s/^PATH=//" | awk '/(^:)|(::)|(:$)|(^\.:)|(:\.:)|(:\.$)|(^\.$)/' ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20

Очекивани излаз: compliant

Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

Examine PATH in /etc/environment to see if it contains any "." or "::" entries: grep "^PATH=" /etc/environment |awk '/((:[ \t]*:)|(:[ \t]*$)|(^[\t]*:)|(^.:)|(:.$)|(:.:))/' If the command above yields output, remove the "." and "::" entries from: vi /etc/environment
