RHSA-2017_3227
Vulnerability from csaf_redhat - Published: 2017-11-15 13:25 - Updated: 2024-11-14 21:45Summary
Red Hat Security Advisory: openstack-aodh security update
Severity
Moderate
Notes
Topic: 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.
Details: 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).
Security Fix(es):
* 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.

Aodh as packaged in Openstack Ocata and Newton before change-ID I8fd11a7f9fe3c0ea5f9843a89686ac06713b7851 and before Pike-rc1 does not verify that trust IDs belong to the user when creating alarm action with the scheme trust+http, which allows remote authenticated users with knowledge of trust IDs where Aodh is the trustee to obtain a Keystone token and perform unspecified authenticated actions by adding an alarm action with the scheme trust+http, and providing a trust id where Aodh is the trustee.
