Summary

Red Hat Security Advisory: openstack-keystone security, bug fix, and enhancement update

Severity

Moderate

Notes

Topic: Updated openstack-keystone packages that fix two security issues, multiple bugs, and add enhancements are now available for Red Hat OpenStack Folsom. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Details: The openstack-keystone packages provide Keystone, a Python implementation of the OpenStack identity service API, which provides Identity, Token, Catalog, and Policy services. The openstack-keystone packages have been upgraded to upstream version 2012.2.1, which provides a number of bug fixes and enhancements over the previous version. (BZ#883829) This update also fixes the following security issues: A flaw in Keystone allowed an attacker with access to the web and network interfaces to continue using chained tokens linked to tokens that had expired. This would allow the attacker to continue using the tokens despite the parent token being expired, giving them continued access to OpenStack services. (CVE-2012-5563) It was found that Keystone did not correctly handle users being removed from tenants when Amazon Elastic Compute Cloud (Amazon EC2) style credentials (credentials that are issued in the same format as standard Amazon EC2 credentials) were in use. When a user was removed from a tenant, they retained the privileges provided by that tenant, allowing them to access resources they should no longer have access to. (CVE-2012-5571) Red Hat would like to thank the OpenStack project for reporting these issues. Upstream acknowledges Anndy as the original reporter of CVE-2012-5563, and Vijaya Erukala as the original reporter of CVE-2012-5571. All users of openstack-keystone are advised to upgrade to these updated packages, which correct these issues and add these enhancements. After installing the updated packages, the Keystone service (openstack-keystone) will be restarted automatically.

CVE-2012-5563

OpenStack Keystone, as used in OpenStack Folsom 2012.2, does not properly implement token expiration, which allows remote authenticated users to bypass intended authorization restrictions by creating new tokens through token chaining. NOTE: this issue exists because of a CVE-2012-3426 regression.

Threats

Impact Moderate

CVE-2012-5571

OpenStack Keystone Essex (2012.1) and Folsom (2012.2) does not properly handle EC2 tokens when the user role has been removed from a tenant, which allows remote authenticated users to bypass intended authorization restrictions by leveraging a token for the removed user role.

CVE-2012-5571 (GCVE-0-2012-5571)

Vulnerability from cvelistv5 – Published: 2012-12-18 01:00 – Updated: 2026-04-07 06:55

Title

Openstack keystone: openstack keystone: authorization bypass via improper ec2 token handling

Summary

A flaw was found in OpenStack Keystone. This vulnerability allows remote authenticated users to bypass intended authorization restrictions. This occurs because OpenStack Keystone does not properly handle EC2 (Elastic Compute Cloud) tokens when a user's role has been removed from a tenant. An attacker can leverage a token associated with a removed user role to gain unauthorized access.

Severity

5.4 (Medium)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
