CVE-2014-0188
First published: Tue Apr 22 2014(Updated: )
Luke Meyer of Red Hat reports: Description of problem: The remote-user auth plugin provides an httpd config file intended to require authentication before setting the REMOTE_USER env var which is passed on to the plugin. However there are passthrough provisions for other forms of auth; in particular, the management console is allowed to set the X-Remote-User header on a request and have that transmuted to the REMOTE_USER env var (by virtue of being a non-proxied local request). When the REMOTE_USER env var is set, the remote-user plugin automatically trusts it. By combining the X-Remote-User header with one of the other passthrough triggers, any user can be impersonated without authenticating at all. Additional info: Simple workaround: add this in the host httpd conf global config, e.g. at the end of /etc/httpd/conf.d/000002_openshift_origin_broker_proxy.conf: RequestHeader unset X-Remote-User
