CVE-2017-11693 & CVE-2017-11694
Overview
------------
Medhost Document Management system for all versions contains hard-coded credentials
used for customer database and Apache Solr access. This is a new vulnerability
not related to CVE-2016-4328 or CVE-2017-11614.
Description
------------
MEDHOST Document Management System contains multiple hard-coded credentials that are
used for customer database and Apache Solr access. An attacker with knowledge of the
hard-coded credentials and the ability to communicate directly with the database and
Apache Solr may be able to obtain or modify sensitive patient and financial
information. PostgreSQL is used as the Document Management System database. The account name
is dms. The Apache Solr account name is also dms. These passwords are hard-coded throughout
the application, and are the same across all installations. Customers do not have the option
to change passwords. The dms account for PostgreSQL has access to the database schema for
Document Management System. The dms account for Apache Solr has access to all indexed
patient documents. PostgreSQL listens on the default TCP port 5432. Apache Solr listens
on the default TCP port 8080.
WEB-INF/classes/database.properties:
# DMS database settings
jdbc.driverClass=org.postgresql.Driver
jdbc.url=jdbc:postgresql://localhost:5432/dms
jdbc.username=dms
jdbc.password=[redacted]
# Liquibase flag
run.liquibase.on.startup = true
WEB-INF/classes/solr.properties:
solr.url=http://localhost:8080/solr/dms
solr.username=dms
solr.password=[redacted]
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.
