Django 1.4.7 release notes

Django 1.4.7 fixes one security issue present in previous Django releases in
|
||
|
|
the 1.4 series.
|
||
|
|
|
||
|
|
Directory traversal vulnerability in :ttag:`ssi` template tag
|
||
|
|
-------------------------------------------------------------
|
||
|
|
|
||
|
|
In previous versions of Django it was possible to bypass the
|
||
|
|
:setting:`ALLOWED_INCLUDE_ROOTS` setting used for security with the :ttag:`ssi`
|
||
|
|
template tag by specifying a relative path that starts with one of the allowed
|
||
|
|
roots. For example, if ``ALLOWED_INCLUDE_ROOTS = ("/var/www",)`` the following
|
||
|
|
would be possible:
|
||
|
|
|
||
|
|
.. code-block:: html+django
|
||
|
|
|
||
|
|
{% ssi "/var/www/../../etc/passwd" %}
|
||
|
|
|
||
|
|
In practice this is not a very common problem, as it would require the template
|
||
|
|
author to put the :ttag:`ssi` file in a user-controlled variable, but it's
|
||
|
|
possible in principle.
