MySQL Server COM_CHANGE_USER Command Security Bypass

This script is Copyright (C) 2013-2015 Tenable Network Security, Inc.

Synopsis :

The remote database server may be affected by a security bypass

Description :

The installed version of MySQL may be affected by a security bypass
vulnerability because the salt used during password validation does not
change when switching users with the 'COM_CHANGE_USER' command.
Additionally, the connection is not reset when invalid credentials are
submitted. Normally, when a connection is initiated and invalid
credentials are submitted, the connection is terminated, which slows
brute-force attempts substantially.
