Django 1.3.4 release notes
|
|
==========================
|
|
|
|
*October 17, 2012*
|
|
|
|
This is the fourth release in the Django 1.3 series.
|
|
|
|
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 1.3.3 and
|
|
Django 1.4.1 -- 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
|
|
"validsite.com"::
|
|
|
|
Host: validsite.com:random@evilsite.com
|
|
|
|
Using this, an attacker can cause parts of Django -- particularly the
|
|
password-reset mechanism -- to generate and display arbitrary URLs to users.
|
|
|
|
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
|
|
:exc:`django.core.exceptions.SuspiciousOperation`.
|
|
|
|
Details of this issue were initially posted online as a `security advisory`_.
