Verify That the MYSQL_PWD Environment Variable is Not in Use

보통레벨 1자동mysql

설명

MySQL can read a default database password from an environment variable called MYSQL_PWD. Avoiding use of this environment variable can better safeguard the confidentiality of MySQL credentials. Run as root; counts processes whose environment contains MYSQL_PWD (including the scanner itself if it was given MYSQL_PWD).

점검 방법

감사 방식: 셸 명령

shell

[ "$(id -u)" -eq 0 ] || exit 1; n=$(grep -lsaz '^MYSQL_PWD=' /proc/[0-9]*/environ 2>/dev/null | wc -l); echo "$n"

예상 출력: 0

조치 방법

조치 방식: 가이드 또는 인프라 패치

Find the processes (grep -lsaz ^MYSQL_PWD= /proc/*/environ) and change the users/scripts that export MYSQL_PWD to use an option file readable only by the user, mysql_config_editor or certificate-based authentication.
