Ensure 'super_priv' is Not Set to 'Y' for Replication Users

高级别 1自动化mysql

说明

The SUPER privilege found in the mysql.user table governs the use of a variety of MySQL features. These features include, CHANGE MASTER TO, KILL, mysqladmin kill option, PURGE BINARY LOGS, SET GLOBAL, mysqladmin debug option, logging control, and more. Treats every account other than root holding REPLICATION SLAVE as a replication user and counts those that also hold SUPER. Runs mysql -NBe with the client defaults: put an administrative account in ~/.my.cnf (mode 0600) or a mysql_config_editor login path, not MYSQL_PWD (see 1.4/1.6).

检查方式

审计方法: SQL 查询

sql_query

out=$(mysql -NBe "SELECT COUNT(*) FROM mysql.user WHERE Repl_slave_priv = 'Y' AND Super_priv = 'Y' AND user NOT IN ('root')" 2>/dev/null) || exit 1; printf '%s\n' "$out"

预期输出: 0

修复方式

修复方法: 操作指南或基础设施补丁

REVOKE SUPER ON *.* FROM '<repl user>'@'<host>'; (grant REPLICATION_SLAVE_ADMIN instead if MySQL Shell ReplicaSet administration needs it).
