what is this query mean

hi, i got worry when i saw this query on the active monitor executed 2 times:

SELECT
dtb.name AS [Name],
dtb.database_id AS [ID],
CAST(case when dtb.name in ('master','model','msdb','tempdb') then 1 else dtb.is_distributor end AS bit) AS [IsSystemObject],
CAST(has_dbaccess(dtb.name) AS bit) AS [IsAccessible]
FROM
master.sys.databases AS dtb
ORDER BY
[Name] ASC

Select allOpen in new window

now, i ask you guys, is this query normal procedure for the sql server sometimes or this is injected?
i only use sql store procedure, so it can't be injected.
