-- 1. Execute after logging in as a regular user (should not see tdsqlsys_* users) SELECT User, Host FROM mysql.user WHERE User LIKE 'tdsqlsys_%'; -- 2. Attempt to create a user with the same prefix (should be rejected by the kernel) CREATE USER 'tdsqlsys_attacker'@'%' IDENTIFIED BY 'fake_pass'; -- ERROR XXXX: User 'tdsqlsys_attacker' is reserved for system use. -- 3. Attempt to write directly via INSERT (should be rejected by the kernel) INSERT INTO mysql.user (User, Host) VALUES ('tdsqlsys_evil','%'); -- ERROR XXXX: Modifying system tables is not allowed. -- 4.

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture
