Ensure Passwords are Set for All OceanBase Accounts

KritikDüzey 1Otomatikoceanbase

Açıklama

If any account exists without a password (i.e., a null-password account), it reduces the attack cost-attackers only need to guess the username correctly to gain access without requiring a password. Therefore, it is essential to ensure that all OceanBase accounts are configured with passwords to prevent unauthorized malicious users from accessing the database. Runs obclient with the connection options in OB_CONN (default "-h127.0.0.1 -P2881 -uroot@sys"); point it at the MySQL-mode tenant being assessed and supply the password via OB_CONN (-p...) or a [client] section in ~/.my.cnf. Passes when neither mysql.user nor oceanbase.__all_user contains an account with an empty password.

Nasıl denetlenir

Denetim yöntemi: SQL sorgusu

sql_query

out=$(obclient ${OB_CONN:--h127.0.0.1 -P2881 -uroot@sys} -N -B -e "SELECT (SELECT COUNT(*) FROM mysql.user WHERE LENGTH(password) = 0) + (SELECT COUNT(*) FROM oceanbase.__all_user WHERE LENGTH(passwd) = 0)" 2>/dev/null) || exit 1; printf '%s\n' "$out"

Beklenen çıktı: 0

Nasıl düzeltilir

Düzeltme yöntemi: Kılavuz veya altyapı yaması
