Vulnerability V-213921

Review system documentation to determine requirements for object ownership and authorization delegation. Use the following query to discover database object ownership: Schemas not owned by the schema or dbo: SELECT name AS schema_name, USER_NAME(principal_id) AS schema_owner FROM sys.schemas WHERE schema_id != principal_id AND principal_id != 1 Objects owned by an individual principal: SELECT object_id, name AS securable, USER_NAME(principal_id) AS object_owner, type_desc FROM sys.objects WHERE is_ms_shipped = 0 AND principal_id IS NOT NULL ORDER BY type_desc, securable, object_owner Use the following query to discover database users who have been delegated the right to assign additional permissions: SELECT U.type_desc, U.name AS grantee, DP.class_desc AS securable_type, CASE DP.class WHEN 0 THEN DB_NAME() WHEN 1 THEN OBJECT_NAME(DP.major_id) WHEN 3 THEN SCHEMA_NAME(DP.major_id) ELSE CAST(DP.major_id AS nvarchar) END AS securable, permission_name, state_desc FROM sys.database_permissions DP JOIN sys.database_principals U ON DP.grantee_principal_id = U.principal_id WHERE DP.state = 'W' ORDER BY grantee, securable_type, securable If any of these rights are not documented and authorized, this is a finding.

To correct object ownership: ALTER AUTHORIZATION ON <Securable> TO <Principal> To revoke any unauthorized permissions: REVOKE [Permission] ON <Securable> TO <Principal>
