CVE-2017-12440

Status Candidate

Overview

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.

Red Hat Security Advisory 2017-3227-01
Posted Nov 17, 2017

Red Hat Security Advisory 2017-3227-01 - openstack-aodh provides the ability to trigger actions based on defined rules against metric or event data collected by OpenStack Telemetry or Time-Series-Database-as-a-Service. Security Fix: 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.

Debian Linux Security Advisory 3953-1 - Zane Bitter from Red Hat discovered a vulnerability in Aodh, the alarm engine for OpenStack. Aodh does not verify that the user creating the alarm is the trustor or has the same rights as the trustor, nor that the trust is for the same project as the alarm. The bug allows that an authenticated users without a Keystone token with knowledge of trust IDs to perform unspecified authenticated actions by adding alarm actions.
