Desc: The issue exist due to the way visLogin.jsp script processes the login
request via the 'EnvironmentUtil.getClientIp(request)' method. It runs a check
whether the request is coming from the local machine and sets the ip variable
to '127.0.0.1' if equal to 0:0:0:0:0:0:0:1. The ip variable is then used as a
username value with the password '123456' to authenticate and disclose sensitive
information and/or do unauthorized actions.
