CVE-2012-4457: OpenStack Keystone Essex before 2012.1.2 and Folsom before folsom-3 does not properly handle authorization...

OpenStack Keystone Essex before 2012.1.2 and Folsom before folsom-3 does not properly handle authorization tokens for disabled tenants, which allows remote authenticated users to access the tenant's resources by requesting a token for the tenant.

Security readout for executives and security teams

This Keystone flaw lets an authenticated OpenStack user obtain authorization for a tenant that has been disabled. If a legacy Essex or early Folsom cloud still exists, disabling a tenant may not reliably stop access to that tenant’s resources. Exposure is most likely in legacy OpenStack deployments running Keystone Essex before 2012.1.2 or Folsom before folsom-3. Modern supported OpenStack releases are not identified as affected in the provided sources. Prioritize if any legacy OpenStack cloud remains in service, especially where tenant disablement is used for suspension, incident response, or offboarding. No active exploitation evidence is provided, but the control failure affects cloud access enforcement. Mitigation focus: Upgrade Keystone Essex to 2012.1.2 or later.; Upgrade Folsom deployments to folsom-3 or later.; Apply the referenced Keystone fixes if maintaining a downstream fork..
