Title: Keystone EC2-style authentication accepts disabled user/tenants
Reporter: Nathanael Burton (National Security Agency)
Products: Keystone
Affects: All versions

Description:
Nathanael Burton reported a vulnerability in EC2-style authentication in Keystone. Keystone fails to check whether a user, tenant, or domain is enabled before authenticating a user using the EC2 api. Authenticated, but disabled users (or authenticated users in disabled tenants or domains) could therefore retain access rights that were thought removed. Only setups enabling EC2-style authentication are affected. To disable EC2-style authentication to work around the issue, remove the ec2_extension from the keystone API pipeline in keystone.conf.
