I need to disagree with you.
With this patch the noVNC is protected from Kimchi perspective
(different from the previous patch), ie,
if the user wants to get the console, he does need to get it from noVNC
source code as you described above
but it will not be possible through Kimchi.
Even with the password parameter you mentioned below, if the user has
the full URL (including the password)
he will be able to get the console from noVNC source code without
authentication.
To the password parameter works, we need to set a random password for
each VNC connection with expiration
time (to reset it after connection is stabilized)
So vm_connect() create a random VNC password with expiration time for
10s (just the enough time to open
connection to noVNC)
That way we ensure each connection has a single valid password and if
someone gets the full URL it won't be valid
anymore.
We need to verify how much work is needed to implement this "password
with expiration time" approach.
Any help is welcome!
