Overview

keystone is a package that provides authentication, authorization and service discovery mechanisms via HTTP primarily for use by projects in the OpenStack family.

Affected versions of this package are vulnerable to Improper Access Control. Any user authenticated within a limited scope (trust/oauth/application credential) can create an EC2 credential with an escalated permission, such as obtaining admin while the user is on a limited viewer role.

This potentially allows a malicious user to act as the admin on a project another user has the admin role on, which can effectively grant that user global admin privileges.
