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. • http://rhn.redhat.com/errata/RHSA-2014-1121.html http://rhn.redhat.com/errata/RHSA-2014-1122.html http://www.openwall.com/lists/oss-security/2014/08/15/6 http://www.ubuntu.com/usn/USN-2324-1 https://bugs.launchpad.net/keystone/+bug/1348820 https://access.redhat.com/security/cve/CVE-2014-5252 https://bugzilla.redhat.com/show_bug.cgi?id=1127250 • CWE-255: Credentials Management Errors CWE-613: Insufficient Session Expiration •

The MySQL token driver in OpenStack Identity (Keystone) 2014.1.x before 2014.1.2.1 and Juno before Juno-3 stores timestamps with the incorrect precision, which causes the expiration comparison for tokens to fail and allows remote authenticated users to retain access via an expired token. El controlador de los tokens MySQL en OpenStack Identity (Keystone) 2014.1.x anterior a 2014.1.2.1 y Juno anterior a Juno-3 almacena las marcas del tiempo (timestamps) con la precisión incorrecta, lo que causa que falle la comparación de la caducidad para los tokens y permite a usuarios remotos autenticados conservar el acceso a través de un token caducado. It was found that the MySQL token driver did not correctly store token expiration times, which prevented manual token revocation. Only OpenStack Identity setups configured to make use of revocation events were affected. • http://rhn.redhat.com/errata/RHSA-2014-1121.html http://rhn.redhat.com/errata/RHSA-2014-1122.html http://www.openwall.com/lists/oss-security/2014/08/15/6 http://www.ubuntu.com/usn/USN-2324-1 https://bugs.launchpad.net/keystone/+bug/1347961 https://access.redhat.com/security/cve/CVE-2014-5251 https://bugzilla.redhat.com/show_bug.cgi?id=1127259 • CWE-255: Credentials Management Errors CWE-613: Insufficient Session Expiration •

OpenStack Identity (Keystone) before 2013.2.4, 2014.x before 2014.1.2, and Juno before Juno-2 allows remote authenticated trustees to gain access to an unauthorized project for which the trustor has certain roles via the project ID in a V2 API trust token request. OpenStack Identity (Keystone) anterior a 2013.2.4, 2014.x anterior a 2014.1.2, y Juno anterior a Juno-2 permite a usuarios remotos autenticados en quien se confía ganar acceso a un proyecto no autorizado para el cual el elemento que establece la confianza tiene ciertos roles a través del identificador del proyecto en una solicitud de token de confianza de la API V2. A flaw was found in the way keystone handled trusts. A trustee could use an out-of-scope project ID to gain unauthorized access to a project if the trustor had the required roles for that requested project. • http://lists.openstack.org/pipermail/openstack-announce/2014-July/000248.html http://secunia.com/advisories/59426 https://bugs.launchpad.net/keystone/+bug/1331912 https://access.redhat.com/security/cve/CVE-2014-3520 https://bugzilla.redhat.com/show_bug.cgi?id=1112668 • CWE-863: Incorrect Authorization •

OpenStack Identity (Keystone) before 2013.2.4, 2014.1 before 2014.1.2, and Juno before Juno-2 does not properly handle chained delegation, which allows remote authenticated users to gain privileges by leveraging a (1) trust or (2) OAuth token with impersonation enabled to create a new token with additional roles. OpenStack Identity (Keystone) anterior a 2013.2.4, 2014.1 anterior a 2014.1.2, y Juno anterior a Juno-2 no maneja debidamente la delegación encadenada, lo que permite a usuarios remotos autenticados ganar privilegios mediante el aprovechamiento de un token (1) trust o (2) OAuth con suplantación habilitada para crear un token nuevo con roles adicionales. A flaw was found in keystone's chained delegation. A trustee able to create a delegation from a trust or an OAuth token could misuse identity impersonation to bypass the enforced scope, possibly allowing them to obtain elevated privileges to the trustor's projects and roles. • http://lists.opensuse.org/opensuse-security-announce/2014-06/msg00031.html http://secunia.com/advisories/57886 http://secunia.com/advisories/59547 http://www.openwall.com/lists/oss-security/2014/06/12/3 http://www.securityfocus.com/bid/68026 https://bugs.launchpad.net/keystone/+bug/1324592 https://access.redhat.com/security/cve/CVE-2014-3476 https://bugzilla.redhat.com/show_bug.cgi?id=1104524 • CWE-269: Improper Privilege Management •
