Ensure root PATH Integrity

Опис

The root user can execute any command on the system and could be tricked into executing programs if the PATH is not set correctly. Including the current working directory (.) or any other writable directory in root's executable path makes it likely that an attacker can gain superuser access by forcing an administrator operating as root to execute a malcode, such as a Trojan horse program. Audit: root's login PATH must not contain ::, a trailing :, '.', or group/other writable directories.

Како се проверава

Метод провере: Команда љуске

shell

p=$(su - root -c 'echo $PATH' 2>/dev/null | tail -n 1); [ -n "$p" ] || exit 1; r=compliant; case "$p" in *::*) r="Empty Directory in PATH (::)";; *:) r="Trailing : in PATH";; esac; IFS=:; set -- $p; unset IFS; for d in "$@"; do [ "$d" = . ] && r="PATH contains ."; if [ -d "$d" ]; then s=$(ls -ld "$d/" | awk 'substr($1,6,1)!="-" {print "Group Write permission set on directory"} substr($1,9,1)!="-" {print "Other Write permission set on directory"}' | head -n 1); [ -z "$s" ] || r="$s $d"; fi; done; echo "$r"

Очекивани излаз: compliant

Како се исправља
