CVE-2019-3683Network attack vector

Authenticated cross-project control via universal member assignment

Published Jan 17, 2020 · Updated Sep 17, 2024

Improper authorization in SUSE OpenStack Cloud 8 allows remote authenticated users to access and control resources in every project. The keystone-json-assignment backend treats every account named in /etc/keystone/user-project-map.json as a member of every project instead of limiting membership to the configured mapping. An account must be present in that mapping and authenticate to Keystone; it can then read, modify, create, or delete arbitrary cloud resources.
