keystone@14.1.0 vulnerabilities

keystone is a package that provides authentication, authorization and service discovery mechanisms via HTTP primarily for use by projects in the OpenStack family.

Affected versions of this package are vulnerable to Information Exposure during account locking. By guessing the name of an account and failing to authenticate multiple times, any unauthenticated actor could both confirm the account exists and obtain that account's corresponding UUID, which might be leveraged for other unrelated attacks.

Upgrade keystone to version 16.0.2, 17.0.1, 18.1.0, 20.0.0 or higher.

keystone is a package that provides authentication, authorization and service discovery mechanisms via HTTP primarily for use by projects in the OpenStack family.

Affected versions of this package are vulnerable to Privilege Escalation. Any authenticated user can create an EC2 credential for themselves for a project that they have a specified role on, and then perform an update to the credential user and project, allowing them to masquerade as another user. This potentially allows a malicious user to act as the admin on a project another user has the admin role on, which can effectively grant that user global admin privileges.

Upgrade keystone to version 15.0.1, 16.0.1 or higher.

keystone is a package that provides authentication, authorization and service discovery mechanisms via HTTP primarily for use by projects in the OpenStack family.

Affected versions of this package are vulnerable to Improper Access Control. The list of roles provided for an OAuth1 access token is silently ignored. Thus, when an access token is used to request a keystone token, the keystone token contains every role assignment the creator had for the project. This results in the provided keystone token having more role assignments than the creator intended, possibly giving unintended escalated access.

Upgrade keystone to version 17.0.0 or higher.

keystone is a package that provides authentication, authorization and service discovery mechanisms via HTTP primarily for use by projects in the OpenStack family.

Affected versions of this package are vulnerable to Improper Authentication. The EC2 API doesn't have a signature TTL check for AWS Signature V4. An attacker can sniff the Authorization header, and then use it to reissue an OpenStack token an unlimited number of times.

Upgrade keystone to version 17.0.0 or higher.

keystone is a package that provides authentication, authorization and service discovery mechanisms via HTTP primarily for use by projects in the OpenStack family.

Affected versions of this package are vulnerable to Improper Access Control. Any user authenticated within a limited scope (trust/oauth/application credential) can create an EC2 credential with an escalated permission, such as obtaining admin while the user is on a limited viewer role.

This potentially allows a malicious user to act as the admin on a project another user has the admin role on, which can effectively grant that user global admin privileges.

Upgrade keystone to version 17.0.0 or higher.
