Red Hat Security Advisory
Synopsis: Moderate: openstack-ironic security update
Advisory ID: RHSA-2016:1377-01
Product: Red Hat Enterprise Linux OpenStack Platform
Advisory URL: https://access.redhat.com/errata/RHSA-2016:1377
Issue date: 2016-07-04
CVE Names: CVE-2016-4985
=====================================================================
1. Summary:
An update for openstack-ironic is now available for Red Hat Enterprise
Linux OpenStack Platform 7.0 (Kilo) for RHEL 7.
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 Enterprise Linux OpenStack Platform 7.0 (Kilo) for RHEL 7 - noarch
3. Description:
OpenStack Bare Metal (ironic) is a tool used to provision bare metal (as
opposed to virtual) machines. It leverages common technologies such as PXE
boot and IPMI to cover a wide range of hardware. It also supports pluggable
drivers to allow added, vendor-specific functionality.
Security Fix(es):
* An authentication vulnerability was found in openstack-ironic. A client
with network access to the ironic-api service could bypass OpenStack
Identity authentication, and retrieve all information about any node
registered with OpenStack Bare Metal. If an unprivileged attacker knew (or
was able to guess) the MAC address of a network card belonging to a node,
the flaw could be exploited by sending a crafted POST request to the node's
/v1/drivers/$DRIVER_NAME/vendor_passthru resource. The response included
the node's full details, including management passwords, even if the
/etc/ironic/policy.json file was configured to hide passwords in API
responses. (CVE-2016-4985)
Red Hat would like to thank the OpenStack Ironic project for reporting
this issue. Upstream acknowledges Devananda van der Veen (IBM) as the
original reporter.
4. Solution:
