Descriptions

The Nova EC2 API security group implementation in OpenStack Compute (Nova) 2013.1 before 2013.2.4 and icehouse before icehouse-rc2 does not enforce RBAC policies for (1) add_rules, (2) remove_rules, (3) destroy, and other unspecified methods in compute/api.py when using non-default policies, which allows remote authenticated users to gain privileges via these API requests.

En la implementación del grupo de seguridad Nova EC2 API en OpenStack Compute (Nova) 2013.1 anterior a 2013.2.4 y icehouse anteior icehouse-rc2 no fuerza políticas RBAC para (1) add_rules, (2) remove_rules, (3) destroy, y otros métodos no especificados en compute/api.py cuando hace uso de políticas no por defecto, lo que permite a los usuarios remotos autenticados obtener privilegios a través de estas peticiones API.

It was found that RBAC policies were not enforced in certain methods of the OpenStack Compute EC2 (Amazon Elastic Compute Cloud) API. A remote attacker could use this flaw to escalate their privileges beyond the user group they were originally restricted to. Note that only certain setups using non-default RBAC rules for OpenStack Compute were affected.

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 found that RBAC policies were not enforced in certain methods of the OpenStack Compute EC2 API. A remote attacker could use this flaw to escalate their privileges beyond the user group they were originally restricted to.
