Published: Translated: NVD NIST

Summary

The identity service in OpenStack Identity (Keystone) before version 2015.1.3 (Kilo) and 8.0.x before 8.0.2 (Liberty) does not properly invalidate authorization tokens when using PKI or PKIZ token providers. This allows remote authenticated users to bypass intended access restrictions and gain access to cloud resources by manipulating byte fields within a revoked token.

Risk Assessment

The organization may be exposed to unauthorized access to cloud resources, potentially leading to data loss or breaches of user privacy.

Recommendation

It is recommended to upgrade to the latest version of OpenStack Identity and keystonemiddleware to ensure proper invalidation of authorization tokens.
