The openshift-origin-broker in Red Hat OpenShift Enterprise 2.0.5, 1.2.7, and earlier does not properly handle authentication requests from the remote-user auth plugin, which allows remote attackers to bypass authentication and impersonate arbitrary users via the X-Remote-User header in a request to a passthrough trigger.

The remote Red Hat Enterprise Linux CoreOS 2 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2014:0423 advisory.

  - OpenShift: openshift-origin-broker plugin allows impersonation (CVE-2014-0188)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Red Hat Enterprise Linux CoreOS 1 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2014:0422 advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Updated openshift-origin-broker and rubygem-openshift-origin-auth-remote-user packages that fix one security issue are now available for Red Hat OpenShift Enterprise 2.0.5.

The Red Hat Security Response Team has rated this update as having Critical security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The openshift-origin-broker package provides the OpenShift Broker service that manages all user logins, DNS name resolution, application states, and general orchestration of the applications.

The rubygem-openshift-origin-auth-remote-user package provides the remote user authentication plug-in.

A flaw was found in the way openshift-origin-broker handled authentication requests via the remote user authentication plug-in. A remote attacker able to submit a request to openshift-origin-broker could set the X-Remote-User header, and send the request to a passthrough trigger, resulting in a bypass of the authentication checks to gain access to any OpenShift user account on the system.
(CVE-2014-0188)

All users of Red Hat OpenShift Enterprise 2.0.5 are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the updated packages, restart the httpd daemon for this update to take effect.
