Summary

The Red Hat Support plug-in for Red Hat OpenStack is a Technology Preview feature which offers seamless integrated access to Red Hat subscription services from the Red Hat OpenStack administration portal. The plug-in provides automated functionality that enables quicker help, answers, and proactive services. It offers easy and instant access to Red Hat exclusive knowledge, resources, engagement, and diagnostic features.
It was found that the local log-viewing function of the redhat-access-plugin for OpenStack Dashboard (horizon) did not sanitize user input. An authenticated user could use this flaw to read an arbitrary file with the permissions of the web server. (CVE-2015-0271)
Red Hat would like to thank Sara Perez Merino of SensePost for reporting this issue.
All redhat-access-plugin-openstack users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.
