MEDHOST Connex Hardcoded Password
Posted on 02 August 2017
CVE-2017-11743 Overview ------------ MEDHOST Connex contains a hard-coded Mirth Connect admin password in all versions. This is a new vulnerability not related to CVE-2016-4328, CVE-2017-11614, CVE-2017-11693 or CVE-2017-11694. Description ------------ MEDHOST Connex contains a hard-coded Mirth Connect admin credential that is used for customer Mirth Connect management access. An attacker with knowledge of the hard-coded credential and the ability to communicate directly with the Mirth Connect management console may be able to intercept sensitive patient information. The admin account password is hard-coded throughout the application, and is the same across all installations. Customers do not have the option to change the Mirth Connect admin account password. The Mirth Connect admin account is created during the Connex install. The plaintext account password is hard-coded multiple times in the Connex install and update scripts. - connex-*.noarch.rpm $ grep password connex-*.noarch.rpm sed -i 's/^password.*/password=$K8t1ng/' /opt/mirthconnect/conf/mirth-cli-config.properties Impact ------------ An attacker with knowledge of the hard-coded credential and the ability to communicate directly with the Mirth Connect management console may be able to obtain sensitive patient 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.
