Advisory URL: https://access.redhat.com/errata/RHSA-2017:3227
Issue date: 2017-11-15
CVE Names: CVE-2017-12440
An update for openstack-aodh is now available for Red Hat OpenStack
Platform 10.0 (Newton).
Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat OpenStack Platform 10.0 - noarch
openstack-aodh provides the ability to trigger actions based on defined
rules against metric or event data collected by OpenStack Telemetry
(ceilometer) or Time-Series-Database-as-a-Service (gnocchi).
* A verification flaw was found in openstack-aodh. As part of an HTTP alarm
action, a user could pass in a trust ID. However, the trust could be from
anyone because it was not verified. Because the trust was then used by
openstack-aodh to obtain a keystone token for the alarm action, a malicious
user could pass in another person's trust ID and obtain a keystone token
containing the delegated authority of that user. (CVE-2017-12440)
This issue was discovered by Luke Hinds (Red Hat). Upstream acknowledges
Zane Bitter (Red Hat) as the original reporter.
