TMA-TDSQL-5.5
Ensure No Excessive `SUPER` Privilege Grants
HighLevel 1Manual reviewtdsql
Description
The SUPER privilege allows many dangerous operations, including modifying global variables, killing other users' queries, and bypassing read-only restrictions.
How it is checked
Audit method: Manual review
This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.
SELECT User, Host FROM mysql.user WHERE Super_priv = 'Y'; Confirm only TDSQL system accounts (such as the necessary tdsqlsys_kp_new) hold the SUPER privilege.
How it is fixed
Fix method: Guidance or infrastructure patch
Revoke the SUPER privilege from unnecessary users: REVOKE SUPER ON *.* FROM 'username'@'host'; In MySQL 8.0, use fine-grained dynamic privileges (such as SYSTEM_VARIABLES_ADMIN, CONNECTION_ADMIN) instead of SUPER.
