A flaw was found in OpenStack Keystone. Tokens obtained via delegated authentication methods (trusts, application credentials, OAuth1 access tokens) can move a credential to an unauthorized project by supplying a new project_id in a PATCH /v3/credentials request, because only the pre-update project is validated against the token's scope. Additionally, tokens obtained by authenticating with a non-delegated EC2 credential bypass the delegation scope restriction entirely and can access all credentials belonging to the same user, including TOTP multi-factor authentication seeds. Successful exploitation allows an attacker to exfiltrate sensitive authentication material or corrupt the project ownership of credentials.
