Security readout for executives and security teams
CVE-2012-5571 lets an authenticated OpenStack Keystone user keep unauthorized tenant access through EC2 token handling after their role is removed. For organizations running affected OpenStack identity services, this can undermine tenant separation and access offboarding. It is not cited as actively exploited in the supplied sources. Exposure is most likely in affected OpenStack Keystone deployments that support EC2-style tokens or credentials, especially where tenant role removals occur. The supplied affected list names Red Hat OpenStack Platform 13, 16.2, 17.1, and 18.0 Keystone packages. Treat this as a moderate-priority cloud identity issue. It requires authenticated access, but it can weaken tenant isolation and offboarding controls. Prioritize systems using Keystone EC2 compatibility or environments with frequent tenant membership changes. Mitigation focus: Apply vendor-provided Keystone security updates from Red Hat, Ubuntu, or OpenStack guidance.; Confirm affected Red Hat OpenStack Platform Keystone packages are upgraded to fixed vendor builds.; Review and revoke EC2 credentials for users removed from tenants..
