Description
transport.py in the SSH server implementation of Paramiko before 1.17.6, 1.18.x before 1.18.5, 2.0.x before 2.0.8, 2.1.x before 2.1.5, 2.2.x before 2.2.3, 2.3.x before 2.3.2, and 2.4.x before 2.4.1 does not properly check whether authentication is completed before processing other requests, as demonstrated by channel-open. A customized SSH client can simply skip the authentication step.
It was found that when acting as an SSH server, paramiko did not properly check whether authentication is completed before processing other requests. A customized SSH client could use this to bypass authentication when accessing any resources controlled by paramiko.
