CVE-2013-7048

OpenStack Compute (Nova) Grizzly 2013.1.4,, La Habana 2013.2.1, y anteriores utilizan con permiso de escritura y lectura universal para el directorio temporal usado para almacenar las instantáneas en vivo (snapshots), lo que permite a usuarios locales leer y modificar instantáneas en vivo (snapshots).

OpenStack Compute launches and schedules large networks of virtual machines, creating a redundant and scalable cloud computing platform. Compute provides the software, control panels, and APIs required to orchestrate a cloud, including running virtual machine instances, managing networks, and controlling access through users and projects. It was discovered that the metadata agent in OpenStack Networking was missing an authorization check on the device ID that is bound to a specific port. A remote tenant could guess the instance ID bound to a port and retrieve metadata of another tenant, resulting in information disclosure. Note that only OpenStack Networking setups running neutron-metadata-agent were affected.
