RealVNC allows remote attackers to bypass authentication and gain unauthorized access to the system via a request in which the VNC client specifies an insecure security type such as "Type 1 - None", which is accepted even if it is not offered by the server.

Intelliadmin released a free proof-of-concept tool to verify the existence of this vulnerability.
