Descriptions

The (1) EC2 and (2) OS APIs in OpenStack Compute (Nova) Folsom (2012.2), Essex (2012.1), and Diablo (2011.3) do not properly check the protocol when security groups are created and the network protocol is not specified entirely in lowercase, which allows remote attackers to bypass intended access restrictions.

Las APIs (1) EC2 y (2) OS en OpenStack Compute (Nova) Folsom (2012.2), Essex (2012.1) y Diablo (2011.3) no comprueban correctamente el protocolo cuando se crean grupos de seguridad y el protocolo de red no se ha especificado por completo en minúsculas, lo que permite a atacantes remotos eludir restricciones de acceso.

It was discovered that, when defining security groups in Nova using the EC2 or OS APIs, specifying the network protocol (e.g. 'TCP') in the incorrect case would cause the security group to not be applied correctly. An attacker could use this to bypass Nova security group restrictions.
