CVE-2015-1852

Status Candidate

Overview

The s3_token middleware in OpenStack keystonemiddleware before 1.6.0 and python-keystoneclient before 1.4.0 disables certification verification when the "insecure" option is set in a paste configuration (paste.ini) file regardless of the value, which allows remote attackers to conduct man-in-the-middle attacks via a crafted certificate, a different vulnerability than CVE-2014-7144.

Red Hat Security Advisory 2015-1685-01
Posted Aug 26, 2015
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2015-1685-01 - Python-keystoneclient is a client library and a command-line utility for interacting with the OpenStack Identity API. It was discovered that some items in the S3Token configuration as used by python-keystoneclient were incorrectly evaluated as strings, an issue similar to CVE-2014-7144. If the "insecure" option was set to "false", the option would be evaluated as true, resulting in TLS connections being vulnerable to man-in-the-middle attacks. Note: The "insecure" option defaults to false, so setups that do not specifically define "insecure=false" are not affected.

Red Hat Security Advisory 2015-1677-01 - Python-keystonemiddleware is a client library and a command line utility for interacting with the OpenStack Identity API. Red Hat Enterprise OpenStack Platform 6.0 contains and uses both the python-keystonemiddleware and python-keystoneclient versions of this package. It was discovered that some items in the the S3Token configuration as used by python-keystonemiddleware and python-keystoneclient were incorrectly evaluated as strings, an issue similar to CVE-2014-7144. This would result in a setting for 'insecure=false' to evaluate as true and leave TLS connections open to MITM.
