Descriptions
OpenStack Keystone, as used in OpenStack Folsom 2012.2, does not properly implement token expiration, which allows remote authenticated users to bypass intended authorization restrictions by creating new tokens through token chaining. NOTE: this issue exists because of a CVE-2012-3426 regression.
OpenStack Keystone, como se usa en OpenStack Folsom 2012.2, no aplica correctamente el vencimiento del token, lo que permite a usuarios autenticados remotamente eludir las restricciones previstas por la creación de nuevos tokens mediante el encadenamiento de token. NOTA: este problema existe debido a una regresión de CVE-2012-3426.
