high Tenable Cloud Security Plugin ID 434992

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2020-12691)
