Openstack tripleo-heat-templates unauthenticated file access
Date: 2022-05
Affected: pip/tripleo-heat-templates
Attack vector: auth-bypass
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2017-12155
CWE: CWE-306
CVSS: 6.3 (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N)

A resource-permission flaw was found in the `tripleo-heat-templates` package where `ceph.client.openstack.keyring` is created as world-readable. A local attacker with access to the key could read or modify data on Ceph cluster pools for OpenStack as though the attacker were the OpenStack service, thus potentially reading or modifying data in an OpenStack Block Storage volume. This has been patched in versions [7.0.6](https://github.com/openstack/tripleo-heat-templates/commit/a18fd59077d97de83496c85c017b9d256a3eddd4) and [8.0.0](https://github.com/openstack/tripleo-heat-templates/commit/ce7b65f443d38a6627631f53cb22336338e97d30).
