CVE-2015-1852
Apache OpenStack Keystone S3 Token Middleware SSL Insecure Verification
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.

Action Type Old Value New Value Changed Description It was discovered that some items in the S3Token paste configuration as used by python-keystonemiddleware (formerly python-keystoneclient) were incorrectly evaluated as strings, an issue similar to CVE-2014-7144. If the "insecure" option were 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.
