TMA-YUGABYTEDB-5.7
Ensure the default password is changed for the yugabyte superuser
Descrição
The yugabyte role is the built-in YSQL superuser in YugabyteDB. By default, it has a well-known password. This default password must be changed before the cluster is deployed to a non-development environment. Leaving the default password in place allows anyone with knowledge of the default to gain full superuser access to all databases in the cluster. The benchmark rates this recommendation Manual; the automated check covers its objective pass criterion. Attempts a ysqlsh login as yugabyte with the default password against PGHOST/PGPORT (default 127.0.0.1:5433); passes only when the login is rejected with an authentication error. A successful login (including trust authentication) fails, an unreachable server fails.
Como é verificado
Método de auditoria: Comando shell
command -v ysqlsh >/dev/null 2>&1 || exit 1; out=$(PGPASSWORD=yugabyte PGPASSFILE=/dev/null ysqlsh -h "${PGHOST:-127.0.0.1}" -p "${PGPORT:-5433}" -U yugabyte -d yugabyte -w -tAc 'SELECT 1' 2>&1); rc=$?; if [ $rc -eq 0 ]; then echo default_password_accepted; elif printf '%s' "$out" | grep -qi 'authentication failed'; then echo compliant; else exit 1; fi- Saída esperada
compliant
Como é corrigido
Método de correção: Orientação ou patch de infraestrutura
ALTER ROLE yugabyte WITH PASSWORD '<new strong password>'; store it in a password vault, and make sure ysql_enable_auth=true (5.6).
