TMA-MYSQL-5.7
Ensure 'GRANT OPTION' is Not Granted to Non-Administrative Users
HighLevel 1Manual reviewmysql
Description
The GRANT OPTION privilege exists in different contexts (mysql.user, mysql.db) for the purpose of governing the ability of a privileged user to manipulate the privileges of other users.
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.
Run SELECT DISTINCT GRANTEE FROM INFORMATION_SCHEMA.USER_PRIVILEGES WHERE IS_GRANTABLE = 'YES'; Ensure only administrative users are returned in the result set.
How it is fixed
Fix method: Guidance or infrastructure patch
REVOKE GRANT OPTION ON *.* FROM '<user>'@'<host>'; for each non-administrative grantee.
