CVE-2014-0105

Status Candidate

Overview

The auth_token middleware in the OpenStack Python client library for Keystone (aka python-keystoneclient) before 0.7.0 does not properly retrieve user tokens from memcache, which allows remote authenticated users to gain privileges in opportunistic circumstances via a large number of requests, related to an "interaction between eventlet and python-memcached."

Red Hat Security Advisory 2014-0442-01

Red Hat Security Advisory 2014-0442-01 - Python-keystoneclient is a client library and a command line utility for interacting with the OpenStack Identity API. The OpenStack Identity auth_token middleware component handles the authentication of tokens with keystone. When using the auth_token middleware with the memcached token cache enabled, a token for a different identity could be returned. An authenticated user could use this flaw to escalate their privileges by making repeated requests that could eventually allow the user to acquire the administrator's identity. Note that only OpenStack Identity setups using auth_token with memcached were affected.

The OpenStack Identity auth_token middleware component handles the authentication of tokens with keystone. The gluster-swift component, provided by Red Hat Storage, requires the auth_token middleware.
