VxRail: Customer Security scan returns vulnerability in VNC on VxRail "the remote vnc server does not require authentication"

When customer runs a security scan, a vulnerability in VNC on VxRail is returned and the message may be shown as similar to "the remote vnc server does not require authentication".

In this particular instance, customer was using Tenable Nessus security software. Teneble reference to this vulerability is https://www.tenable.com/plugins/index.php?view=single&id=26925 which states:

** The VNC server sometimes sends the connected user to the XDM login
** screen. Unfortunately, Nessus cannot identify this situation.
** In such a case, it is not possible to go further without valid
** credentials and this alert may be ignored.

VNC server on VxRail Manager is only activated after ESRS is activated and can only be accessed from EMC Support secure channel, which will then redirect to the XDM login on the VxRail.

So for VxRail, the VNC server does, in fact, send the connected user to the XDM login and can go no further without valid credentials.
