Ensure root path integrity

VisokaNivo 1Automatskafreebsd

Opis

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. Including the current working directory (.) or 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 Trojan horse program. Audit: root's login PATH must not contain ::, a trailing :, '.', non-directories, or directories not owned by root or writable by group/other.

Kako se proverava

Metod provere: Komanda ljuske

shell

p=$(su - root -c 'echo $PATH' 2>/dev/null | tail -n 1); [ -n "$p" ] || exit 1; r=compliant; case "$p" in *::*) r="PATH contains an empty directory (::)";; *:) r="PATH has a trailing :";; 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)=="w" || substr($1,9,1)=="w" || $3!="root" {print $1, $3}'); [ -z "$s" ] || r="$d: $s"; elif [ -n "$d" ]; then r="$d is not a directory"; fi; done; echo "$r"

Očekivani izlaz: compliant

Kako se ispravlja
