A resource-permission flaw was found in the openstack-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.

    To mitigate the flaw, use an overcloud post-deploy script[1] to do the following on all overcloud nodes: key=/etc/ceph/ceph.client.openstack.keyring chown root:root $key chmod 600 $key setfacl -m u:glance:r $key setfacl -m u:cinder:r $key setfacl -m u:nova:r $key setfacl -m u: gnocchi:r $key If not using Red Hat OpenStack Platform director, then run the commands above manually on each overcloud node, Warning: Only running 'chmod 600 $key' alone (without an ACL) will prevent OpenStack from reading the key.

  • GHSA-w8gx-hhcx-px6wOpenstack tripleo-heat-templates unauthenticated file access2022-05-13ghsa · osvUS

    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).
