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.

  - Fix for protocol case handling (CVE-2012-2654)

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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.
