  1. CVE-2020-12689

    Hoch · CVSS 8.8EPSS 1,56%Korrektur verfügbar

    CVE-2020-12689

    An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. 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.

  2. CVE-2020-12690

    Hoch · CVSS 8.8EPSS 1,9%Korrektur verfügbar

    CVE-2020-12690

    An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. 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.

  3. CVE-2020-12691

    Hoch · CVSS 8.8EPSS 4,92%Korrektur verfügbar

    CVE-2020-12691

    An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. 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.
