Youtube videos that shows how to exploit libSSH by using this PoC (Proof Of Concept)
Find the right server with these fingerprints:
https://gist.github.com/0x4D31/35ddb0322530414bbb4c3288292749cc
Check the version of server that you trying to bypass with testversionofserver.py
If output is 0.7.5, 0.6.*, or lowest then the server is vulnerable.
If isn't then it's probably patched, truncated or not using libSSH.
