OSSA-2012-013: Lack of authorization for adding users to tenants¶
- Date:
August 30, 2012
- CVE:
CVE-2012-3542
Affects¶
Keystone: Essex, Folsom
Description¶
Dolph Mathews reported a vulnerability in Keystone. When attempting to update a user’s default tenant, Keystone will only partially deny the request when a user is not authorized to complete this action. The API responds with 401 Not Authorized and the user’s default tenant is not changed. However, the user is still granted membership to this new tenant.The result is that any client that can reach the administrative API (deployed on port 35357, by default) can add any user to any tenant.
