45233.py multiple CryptographyDeprecationWarning [Kali 2020.1]

[aenagy]

Trying to run 45233.py (https://github.com/offensive-security/exploitdb/blob/master/exploits/linux/remote/45233.py) I get get

import paramiko
ImportError: No module named paramiko

So I try 'pip install paramiko' (https://stackoverflow.com/questions/28173520/importerror-no-module-named-paramiko). That generated another error (sorry, not output) which lead me to 'pip install paramiko==2.0.8' (https://github.com/paramiko/paramiko/issues/1314). Then I try again and get:

Based on the link below it seems that this script needs to be updated.
