Description
Within the database, object ownership implies full privileges to the owned object, including the privilege to assign access to the owned objects to other subjects. Database functions and procedures can be coded using definer's rights. This allows anyone who utilizes the object to perform the actions if they were the owner. If not properly managed, this can lead to privileged actions being taken by unauthorized individuals.

ℹ️ Check
Review system documentation to identify Azure SQL Managed Instance accounts authorized to own database objects. If the Azure SQL Managed Instance ownership list does not exist or needs to be updated, this is a finding. The following query can be used to make this determination: ;with objects_cte as (SELECT o.name, o.type_desc, CASE WHEN o.principal_id is null then s.principal_id ELSE o.principal_id END as principal_id FROM sys.objects o INNER JOIN sys.schemas s ON o.schema_id = s.schema_id WHERE o.is_ms_shipped = 0 ) SELECT cte.name, cte.type_desc, dp.name as ObjectOwner FROM objects_cte cte INNER JOIN sys.database_principals dp ON cte.principal_id = dp.principal_id ORDER BY dp.name, cte.name If any of the listed owners is not authorized, this is a finding.

✔️ Fix
Document and obtain approval for any account(s) authorized for object ownership. If necessary, use the ALTER AUTHORIZATION command to change object ownership to an authorized account. Example provided below. ALTER AUTHORIZATION ON OBJECT::test.table TO AuthorizedUser; Refer to: https://docs.microsoft.com/en-us/sql/t-sql/statements/alter-authorization-transact-sql
