Execution of software modules (to include stored procedures, functions, and triggers) with elevated privileges must be restricted to necessary cases only.

Description
In certain situations, to provide required functionality, a Database Management System (DBMS) needs to execute internal logic (stored procedures, functions, triggers, etc.) and/or external code modules with elevated privileges. However, if the privileges required for execution are at a higher level than the privileges assigned to organizational users invoking the functionality applications/programs, those users are indirectly provided with greater privileges than assigned by organizations. Privilege elevation must be utilized only where necessary and protected from misuse.

Check Text (C-235180r961359_chk)

Review the server documentation to obtain a listing of accounts used for executing external processes. Execute the following query to obtain a listing of accounts currently configured for use by external processes. SHOW PROCEDURE STATUS where security_type <> 'INVOKER'; SHOW FUNCTION STATUS where security_type <> 'INVOKER'; If DEFINER accounts are returned that are not documented and authorized, this is a finding. If elevation of MySQL privileges using DEFINER is documented, but not implemented as described in the documentation, this is a finding. If the privilege-elevation logic can be invoked in ways other than intended, or in contexts other than intended, or by subjects/principals other than intended, this is a finding.

Fix Text (F-38362r623661_fix)

Remove any procedures that are not authorized. Drop the procedure or function using DROP PROCEDURE <proc_name>; DROP FUNCTION <function_name>;
