MEDHOST Connex Hard-Coded Credentials

`Overview  
------------  
  
MEDHOST Connex for all versions contains hard-coded credentials that  
are used for customer  
database access. This is a new vulnerability not related to CVE-2016-4328.  
  
Description  
------------  
  
MEDHOST Connex contains hard-coded credentials that are used for  
customer database  
access. An attacker with knowledge of the hard-coded credentials and the ability  
to communicate directly with the database may be able to obtain  
or modify sensitive patient and financial information.  
  
Connex utilizes an IBM i DB2 user account for database access. The  
account name is HMSCXPDN.  
This password is hard-coded in multiple places of the application.  
Customers do not have the option to change this password. The account  
has elevated DB2 roles, and can access all objects or database tables  
on the customer DB2 database. This account can access data through  
odbc, ftp, and telnet.  
  
Customers w/o Connex installed are still vulnerable. The MEDHOST setup  
program creates this account. Connex provides connectivity to exchange  
clinical information with the MEDHOST application. /1  
  
Impact  
------------  
  
An attacker with knowledge of the hard-coded credentials and the  
ability to communicate  
directly with the application database server may be able to obtain or  
modify patient  
and financial information.  
  
Solution  
------------  
  
The vendor has not issued a patch and has been unresponsive to this  
information after 3 attempts  
to communicate.  
  
Restrict network access  
  
As a general security practice, only allow connections from trusted  
hosts and networks.  
Restricting access would prevent an attacker from using the hard-coded  
database credentials  
from a blocked network location.
