CVE-2013-2256: OpenStack Compute (Nova) before 2013.1.3 and Havana before havana-2 does not properly enforce the os-flavor...

OpenStack Compute (Nova) before 2013.1.3 and Havana before havana-2 does not properly enforce the os-flavor-access:is_public property, which allows remote authenticated users to obtain sensitive information (flavor properties), boot arbitrary flavors, and possibly have other unspecified impacts by guessing the flavor id.

Security readout for executives and security teams

This is an old OpenStack Nova access-control flaw. An authenticated cloud user could potentially discover private flavor details and start instances using flavors they should not be allowed to use, by guessing a flavor identifier. The main business risk is tenant isolation failure and resource control bypass in exposed, unpatched Nova deployments. Exposure is limited to OpenStack Compute Nova deployments running versions before 2013.1.3 or Havana before havana-2, especially multi-tenant clouds using private flavors for access control or resource governance. Prioritize remediation if any affected Nova deployment still hosts tenants or exposes Nova APIs. For retired or isolated legacy environments, confirm decommissioning or compensating controls before accepting residual risk. Mitigation focus: Upgrade Nova to 2013.1.3, Havana havana-2, or later supported fixed releases.; Apply relevant vendor packages, including Red Hat guidance where applicable.; Check vendor advisories for supported backported fixes on distribution-managed OpenStack..
