CVE-2012-2654: n/a vulnerability

CVE-2012-2654: The (1) EC2 and (2) OS APIs in OpenStack Compute (Nova) Folsom (2012.2), Essex (2012.1), and Diablo (2011.3...

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.

Security readout for executives and security teams

This flaw affects old OpenStack Compute Nova releases. Security group rules could be created incorrectly when the network protocol was not entirely lowercase, allowing intended access restrictions to be bypassed. The business risk is unexpected network exposure in legacy OpenStack environments. Exposure is most likely in legacy OpenStack Nova deployments, derivatives, or archived appliances based on Folsom, Essex, or Diablo. Modern supported OpenStack environments are not identified as affected in the provided sources. Treat this as a legacy-platform exposure issue. Prioritize if old OpenStack environments still host sensitive systems or internet-reachable workloads. Otherwise, document non-exposure through inventory evidence. Mitigation focus: Identify any Nova Folsom, Essex, or Diablo deployments still in service.; Apply vendor-provided updates referenced by OpenStack or operating system advisories.; Review Ubuntu USN-1466-1 if using Ubuntu-packaged Nova..
