RealVNC Authentication Bypass Vulnerability Vulnerability Scan

Vulnerability Scan Summary
Tries to bypass authentication using RealVNC

Detailed Explanation for this Vulnerability Test

Synopsis :

The remote VNC server is prone to an authentication bypass issue.

Description :

The remote host appears to be running RealVNC, a VNC server for
Windows and Linux/unix platforms.

The version of RealVNC installed on the remote host allows a possible hacker
to bypass authentication by simply requesting 'Type 1 - None' as the
authentication type even though it is not explicitly configured to
support that. By exploiting this issue, a possible hacker gains access to
the affected host at the privilege level under which RealVNC operates,
typically as Administrator under Windows.
