TMA-OCEANBASE-4.1.7
Ensure No Users Have Wildcard Hostnames
Beschreibung
All user accounts in the database should be strictly restricted to connect only from specific hosts or IP addresses explicitly required for their business operations. 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 no account has host '%' (the defaults root@% and ORAAUDITOR@% fail until restricted).
So wird geprüft
Prüfmethode: SQL-Abfrage
out=$(obclient ${OB_CONN:--h127.0.0.1 -P2881 -uroot@sys} -N -B -e "SELECT COUNT(*) FROM mysql.user WHERE host = '%'" 2>/dev/null) || exit 1; printf '%s\n' "$out"- Erwartete Ausgabe
0
So wird behoben
Behebungsmethode: Anleitung oder Infrastruktur-Patch
RENAME USER '<user>'@'%' TO '<user>'@'<approved host or subnet>'; for every account returned.
