You're telling me that, basically, an attacker says "you've already said you trust me" and the server answers "sure, I did"? Wow.
"libssh versions 0.6 and above have an authentication bypass vulnerability in
the server code. By presenting the server an SSH2_MSG_USERAUTH_SUCCESS message
in place of the SSH2_MSG_USERAUTH_REQUEST message which the server would expect
to initiate authentication, the attacker could successfully authentciate
without any credentials.
The bug was discovered by Peter Winter-Smith of NCC Group."
