SQL Server credentials required: Yes (use ms-sql-brute, ms-sql-empty-password and/or 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. 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. ]] --- -- @usage -- nmap -p 1433 --script ms-sql-config --script-args mssql.username=sa,mssql.password=sa -- -- @args ms-sql-config.showall If set, shows all configuration options. -- -- @output -- | ms-sql-config: -- | [192.168.100.25\MSSQLSERVER] -- | Databases -- | name db_size owner -- | ==== ======= ===== -- | nmap 2.74 MB MAC-MINI\david -- | Configuration -- | name value inuse description -- | ==== ===== ===== =========== -- | SQL Mail XPs 0 0 Enable or disable SQL Mail XPs -- | Database Mail XPs 0 0 Enable or disable Database Mail XPs -- | SMO and DMO XPs 1 1 Enable or disable SMO and DMO XPs -- | Ole Automation Procedures 0 0 Enable or disable Ole Automation Procedures -- | xp_cmdshell 0 0 Enable or disable command shell -- | Ad Hoc Distributed Queries 0 0 Enable or disable Ad Hoc Distributed Queries -- | Replication XPs 0 0 Enable or disable Replication XPs -- | Linked Servers -- | srvname srvproduct providername -- | ======= ========== ============ -- |_ MAC-MINI SQL Server SQLOLEDB -- -- Created 04/02/2010 - v0.1 - created by Patrik Karlsson -- Revised 02/01/2011 - v0.2 - Added ability to run against all instances on a host; -- added compatibility with changes in mssql.lua (Chris Woodbury) author = "Patrik Karlsson" license = "Same as Nmap--See https://nmap.org/book/man-legal.html" categories = {"discovery", "safe"} dependencies = {"ms-sql-brute", "ms-sql-empty-password"} hostrule = mssql.Helper.GetHostrule_Standard() portrule = mssql.Helper.GetPortrule_Standard() --- Processes a set of instances local function process_instance( instance ) local status, errorMessage local result, result_part = {}, {} local conf_filter = stdnse.get_script_args( {'mssql-config.showall', 'ms-sql-config.showall'} ) and "" or " WHERE configuration_id > 16384" local db_filter = stdnse.get_script_args( {'mssql-config.showall', 'ms-sql-config.showall'} ) and "" or " WHERE name NOT IN ('master','model','tempdb','msdb')" local helper = mssql.Helper:new() local queries = { [2]={ ["Configuration"] = [[ SELECT name, cast(value as varchar) value, cast(value_in_use as varchar) inuse, description FROM sys.configurations ]] .. conf_filter }, [3]={ ["Linked Servers"] = [[ SELECT srvname, srvproduct, providername FROM master..sysservers WHERE srvid > 0 ]] }, [1]={ ["Databases"] = [[ CREATE TABLE #nmap_dbs(name varchar(255), db_size varchar(255), owner varchar(255), dbid int, created datetime, status varchar(512), compatibility_level int ) INSERT INTO #nmap_dbs EXEC sp_helpdb SELECT name, db_size, owner FROM #nmap_dbs ]] .. db_filter ..
