Ensure No Users Have Wildcard Hostnames

中级别 1自动化mysql

说明

MySQL can make use of host wildcards when granting permissions to users on specific databases. For example, you may grant a given privilege to '<user>'@'%'. 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=$(mysql -NBe "SELECT COUNT(*) FROM mysql.user WHERE host = '%'" 2>/dev/null) || exit 1; printf '%s\n' "$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

For each SELECT user, host FROM mysql.user WHERE host = '%' result: RENAME USER '<user>'@'%' TO '<user>'@'<specific host>'; or DROP USER.
