Openstack · Openstack Identity · CVE-2013-6391
**Name of the Vulnerable Software and Affected Versions**
OpenStack Identity (Keystone) versions before Havana 2013.2.1
OpenStack Identity (Keystone) versions before Icehouse icehouse-2
**Description**
The issue concerns the ec2tokens API in OpenStack Identity (Keystone), where it fails to return a trust-scoped token when one is received. This allows remote trust users to gain privileges by generating EC2 credentials from a trust-scoped token and using them in an ec2tokens API request, such as the "/ec2tokens" API endpoint, with potentially vulnerable parameters like `trust id` or `token`.
**Recommendations**
For OpenStack Identity (Keystone) versions before Havana 2013.2.1, update to Havana 2013.2.1 or later to resolve the issue.
For OpenStack Identity (Keystone) versions before Icehouse icehouse-2, update to Icehouse icehouse-2 or later to resolve the issue.
