Overview

CVE-2015-1852 is a medium-severity vulnerability affecting openstack keystonemiddleware. It was published on April 17, 2015 and has a CVSS 2.0 base score of 4.3 (MEDIUM).

This vulnerability has a CVSS 2.0 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories and patches from openstack. Update keystonemiddleware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
