RealVNC Authentication Bypass Vulnerability |
||
|
Tries to bypass authentication using RealVNC Detailed Explanation for this Vulnerability Assessment Summary : 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 permits 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.
