Ensure No Users Have Wildcard Hostnames

中等級 1自動化mysql

說明

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).

檢查方式

稽核方法: SQL 查詢

sql_query

out=$(mysql -NBe "SELECT COUNT(*) FROM mysql.user WHERE host = '%'" 2>/dev/null) || exit 1; printf '%s\n' "$out"

預期輸出: 0

修補方式

修補方法: 操作指南或基礎設施修補檔

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