CVE-2014-0188

El openshift-origin-broker en Red Hat OpenShift Enterprise 2.0.5, 1.2.7, y anteriores no maneja adecuadamente las peticiones de autenticación provenientes del plugin de autenticación de usuarios remotos, lo que permite a atacantes remotos evitar la autenticación y suplantar a usuarios arbitrarios a través de las cabeceras X-Remote-User en las peticiones provocando un bypass.

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.
