Openstack · Openstack Keystonemiddleware · CVE-2015-1852
**Name of the Vulnerable Software and Affected Versions**
OpenStack keystonemiddleware versions prior to 1.6.0
python-keystoneclient versions prior to 1.4.0
**Description**
The issue allows remote attackers to conduct man-in-the-middle attacks via a crafted certificate when the `insecure` option is set in a paste configuration file, regardless of its value. This is due to the s3 token middleware disabling certification verification.
**Recommendations**
For OpenStack keystonemiddleware versions prior to 1.6.0, update to version 1.6.0 or later to resolve the issue.
For python-keystoneclient versions prior to 1.4.0, update to version 1.4.0 or later to resolve the issue.
As a temporary workaround, consider removing the `insecure` option from the paste configuration file to prevent the disabling of certification verification.
