Improper Access Control

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.

How to fix Improper Access Control?

Upgrade keystone to version 17.0.0 or higher.

Improper Authentication

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.

How to fix Improper Authentication?

Upgrade keystone to version 17.0.0 or higher.

Improper Access Control

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.

How to fix Improper Access Control?

Upgrade keystone to version 17.0.0 or higher.

Privilege Escalation

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 via the list credentials API. Any user with a role on a project is able to list any credentials with the /v3/credentials API when enforce_scope is false.

How to fix Privilege Escalation?

Upgrade keystone to version 17.0.0 or higher.
