The identity service in OpenStack Identity (Keystone) before 2015.1.3 (Kilo) and 8.0.x before 8.0.2 (Liberty) and keystonemiddleware (formerly python-keystoneclient) before 1.5.4 (Kilo) and Liberty before 2.3.3 does not properly invalidate authorization tokens when using the PKI or PKIZ token providers, which allows remote authenticated users to bypass intended access restrictions and gain access to cloud resources by manipulating byte fields within a revoked token. El servicio de identificación en OpenStack Identity (Keystone) en versiones anteriores a 2015.1.3 (Kilo) y 8.0.x en versiones anteriores a 8.0.2 (Liberty) y keystonemiddleware (anteriormente python-keystoneclient) en versiones anteriores a 1.5.4 (Kilo) y Liberty en versiones anteriores a 2.3.3 no invalida correctamente los tokens de autorización cuando utiliza los proveedores de token PKI o PKIZ, lo que permite a usuarios remotos autenticados eludir las restricciones de acceso previstas y obtener acceso a recursos de la nube manipulando los campos byte dentro de un token revocado. • http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.securityfocus.com/bid/80498 https://bugs.launchpad.net/keystone/+bug/1490804 https://security.openstack.org/ossa/OSSA-2016-005.html https://wiki.openstack.org/wiki/OSSN/OSSN-0062 • CWE-522: Insufficiently Protected Credentials •
