Queries Microsoft SQL Server (ms-sql) instances for a list of databases a user has access to.

- Host script: Will run if the
mssql.instance-portscript arguments are used (see mssql.lua).
- Port script: Will run against any services identified as SQL Servers, but only
mssql.instance-portscript arguments are NOT used.
The script needs an account with the sysadmin server role to work.
When run, the script iterates over the credentials and attempts to run the command for each available set of credentials.
NOTE: The "owner" field in the results will be truncated at 20 characters. This
is a limitation of the
sp_MShasdbaccess stored procedure that the
NOTE: Communication with instances via named pipes depends on the
library. To communicate with (and possibly to discover) instances via named pipes,
the host must have at least one SMB port (e.g. TCP 445) that was scanned and
found to be open. Additionally, named pipe connections may require Windows
authentication to connect to the Windows host (via SMB) in addition to the
authentication required to connect to the SQL Server instances itself. See the
documentation and arguments for the
smb library for more information.
NOTE: By default, the ms-sql-* scripts may attempt to connect to and communicate
with ports that were not included in the port list for the Nmap scan. This can
be disabled using the
mssql.scanned-ports-only script argument.
