Descriptions

The V3 API in OpenStack Identity (Keystone) 2014.1.x before 2014.1.2.1 and Juno before Juno-3 updates the issued_at value for UUID v2 tokens, which allows remote authenticated users to bypass the token expiration and retain access via a verification (1) GET or (2) HEAD request to v3/auth/tokens/.

La API V3 en OpenStack Identity (Keystone) 2014.1.x anterior a 2014.1.2.1 y Juno anterior a Juno-3 actualiza el valor issued_at para los tokens UUID v2, loque permite a usuarios remotos autenticados evadir la caducidad de tokens y conservar el acceso a través de una solicitud (1) GET o (2) HEAD de verificación en v3/auth/tokens/.

A flaw was found in keystone revocation events that resulted in the "issued_at" time being updated when a token created by the V2 API was processed by the V3 API. This could allow a user to evade token revocation. Only OpenStack Identity setups configured to make use of revocation events and UUID tokens were affected.
