AI-suggested

European organizations should immediately verify their OpenStack Keystone versions and upgrade to versions 26.0.1 or later, 27.0.1 or later, or 28.0.1 or later where the vulnerability is patched. If upgrading is not immediately feasible, organizations should implement strict network controls to limit access to Keystone endpoints, especially /v3/ec2tokens and /v3/s3tokens, restricting them to trusted sources only. Review and audit the use of AWS Signature-based authentication within Keystone to ensure it is configured securely and monitored for anomalies. Employ enhanced logging and alerting on token generation requests to detect unusual patterns indicative of exploitation attempts. Conduct regular penetration testing and vulnerability assessments focused on identity services. Additionally, consider implementing multi-factor authentication and role-based access controls to reduce the impact of compromised tokens. Collaborate with cloud service providers to ensure timely patch deployment and share threat intelligence related to this vulnerability. Finally, update incident response plans to include scenarios involving Keystone authorization bypass.

Description

OpenStack Keystone before 26.0.1, 27.0.0, and 28.0.0 allows a /v3/ec2tokens or /v3/s3tokens request with a valid AWS Signature to provide Keystone authorization.
