This module implements the Tabular Data Stream protocol which is used by Microsoft SQL Server. It listens to tcp/1433 and allows clients to login. It can decode queries run on the database, but as there is no database, dionaea can’t reply, and there is no further action. Typically we always get the same query:

exec sp_server_info 1 exec sp_server_info 2 exec sp_server_info 500 select 501,NULL,1 where 'a'='A' select 504,,c.description,c.definition from master.dbo.syscharsets c,master.dbo.syscharsets c1,master.dbo.sysconfigures f where f.config=123 and and set textsize 2147483647 set arithabort on

Refer to the blog <> for more information. Patches would be appreciated.
