Synopsis :

The remote FreeBSD host is missing one or more security-related

Description :

The Django Project reports :

- Host header poisoning

Some parts of Django -- independent of end-user-written applications
-- make use of full URLs, including domain name, which are generated
from the HTTP Host header. Some attacks against this are beyond
Django's ability to control, and require the web server to be properly
configured; Django's documentation has for some time contained notes
advising users on such configuration.

Django's own built-in parsing of the Host header is, however, still
vulnerable, as was reported to us recently. The Host header parsing in
Django 1.3 and Django 1.4 -- specifically,
django.http.HttpRequest.get_host() -- was incorrectly handling
username/password information in the header. Thus, for example, the
following Host header would be accepted by Django when running on
'' :

Host:[email protected]

Using this, an attacker can cause parts of Django -- particularly the
password-reset mechanism -- to generate and display arbitrary URLs to

To remedy this, the parsing in HttpRequest.get_host() is being
modified; Host headers which contain potentially dangerous content
(such as username/password pairs) now raise the exception

- Documentation of HttpOnly cookie option

As of Django 1.4, session cookies are always sent with the HttpOnly
flag, which provides some additional protection from cross-site
scripting attacks by denying client-side scripts access to the session

Though not directly a security issue in Django, it has been reported
that the Django 1.4 documentation incorrectly described this change,
by claiming that this was now the default for all cookies set by the
HttpResponse.set_cookie() method.

The Django documentation has been updated to reflect that this only
applies to the session cookie. Users of Django are encouraged to
review their use of set_cookie() to ensure that the HttpOnly flag is
being set or unset appropriately.
