In case the solution provided by rebus is still erroring out, I’ve found a working solution.
If you have an older version of Impacket, purge it, then delete all of the python files within /usr/bin.
Once done, install v0.10.0 via the following link: GitHub - fortra/impacket: Impacket is a collection of Python classes for working with network protocols.
Then create you a new openssl.cnf file in a new directory (such as folder with the box name). Within the file, add the following contents:
openssl_conf = default_conf
[ default_conf ]
ssl_conf = ssl_sect
[ssl_sect]
system_default = system_default_sect
[system_default_sect]
MinProtocol = TLSv1
CipherString = DEFAULT:@SECLEVEL=0
Now while using the mssqlclient command, pre-pend the following command: OPENSSL_CONF=./name of file.cnf
Also don’t forget to append -windows-auth at the end
My full version of the command is as follows: OPENSSL_CONF=./openssl.cnf
mssqlclient.py ARCHETYPE/:@ -windows-auth
