CVE-2022-3146

Credential disclosure via world-readable clouds.yaml file

Published Mar 23, 2023 · Updated Feb 25, 2025

Incorrect default permissions in OpenStack tripleo-ansible allow local users to read deployment credentials from /etc/openstack/clouds.yaml. The tripleo-keystone-resources role creates that root-owned file with mode 0644, making its plaintext undercloud and overcloud passwords readable by all local accounts. Successful access discloses cloud credentials and configuration details but does not directly alter the deployment.
