Kerentanan Improper Privilege Management pada openstack keystone, canonical ubuntu linux. Skor CVSS 3.1 8.8 (High) menurut NVD.

Deskripsi (NVD)

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.
