User Summary

Attempts to authenticate to Microsoft SQL Servers using an empty password for the sysadmin (sa) account.

SQL Server credentials required: No (will not benefit from mssql.username & mssql.password). Run criteria:

Host script: Will run if the mssql.instance-all, mssql.instance-name

or mssql.instance-port script arguments are used (see mssql.lua).

Port script: Will run against any services identified as SQL Servers, but only

if the mssql.instance-all, mssql.instance-name and mssql.instance-port script arguments are NOT used.

WARNING: SQL Server 2005 and later versions include support for account lockout policies (which are enforced on a per-user basis).

NOTE: Communication with instances via named pipes depends on the smb 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.

Script Arguments

mssql.domain, mssql.instance-all, mssql.instance-name, mssql.instance-port, mssql.password, mssql.protocol, mssql.scanned-ports-only, mssql.timeout, mssql.username
