keystonemiddleware/keystoneclient: S3Token TLS cert verification option not honored
Published Apr 17, 2015
8.7
HIGHCVSS 4.0
EPSS 2.61%
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.
