Opis

Users with the SUPER or SYSTEM_VARIABLES_ADMIN privilege can modify system variables online via SET GLOBAL, including security-related parameters (such as sql_mode, read_only).

Kako se proverava

Metod provere: Ručni pregled

Ova preporuka se ne može proveriti automatski. Skeniranje je navodi sa ovim uputstvima kada prosledite --include-manual.

Run SELECT User, Host FROM mysql.user WHERE Super_priv = 'Y' AND User NOT LIKE 'tdsqlsys%'; and check SYSTEM_VARIABLES_ADMIN grants (SELECT * FROM mysql.global_grants WHERE PRIV = 'SYSTEM_VARIABLES_ADMIN'). Only TDSQL system accounts may hold them; with audit logging enabled, review the audit trail for unexpected SET GLOBAL statements.

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

1. Allow only TDSQL system accounts (tdsqlsys_*) to hold the SUPER privilege. 2. Have business accounts modify parameters uniformly through the OSS management interface. 3. Enable audit logging of SET GLOBAL operations.
