Fixed In Version: django 1.9.10, django 1.8.15
Doc Type: If docs needed, set a value
Doc Text:
A CSRF flaw was found in Django, where an interaction between Google Analytics and Django's cookie parsing could allow an attacker to set arbitrary cookies leading to a bypass of CSRF protection. In this update, the parser for ''request.COOKIES'' has been simplified to better match browser behavior and to mitigate this attack. ''request.COOKIES'' may now contain cookies that are invalid according to RFC 6265 but are possible to set using ''document.cookie''.

Description Andrej Nemec 2016-09-19 13:56:57 UTC 
An interaction between Google Analytics and Django's cookie parsing
could allow an attacker to set arbitrary cookies leading to a bypass of
CSRF protection.

The parser for ``request.COOKIES`` is simplified to better match the
behavior of browsers and to mitigate this attack. ``request.COOKIES``
may now contain cookies that are invalid according to RFC 6265 but are
possible to set via ``document.cookie``.

Statement:

This issue did not affect the versions of calamari-server as shipped with Red Hat Ceph Storage 1.3 and 2.0 as they did not include support for google analytics with Django.
