Bugzilla Bug 222029

Description of vulnerability

The Django administration application will, when accessed by a user who is not
sufficiently authenticated, display a login form and ask the user to provide
the necessary credentials before displaying the requested page. This form will
be submitted to the URL the user attempted to access, by supplying the current
request path as the value of the form's "action" attribute.

The value of the request path was not being escaped, creating an opportunity
for a cross-site scripting (XSS) attack by leading a user to a URL which
contained URL-encoded HTML and/or JavaScript in the request path.
Affected versions

    * Django development trunk
    * Django 0.96
    * Django 0.95
    * Django 0.91

Resolution

The login form has been changed to escape the request path before use as the
form's submission action.

The relevant changesets for affected versions of Django are:

    * Django development trunk: Changeset 7521
    * Django 0.96: Changeset 7527
    * Django 0.95: Changeset 7528
    * Django 0.91: Changeset 7529

The following releases have been issued based on the above changesets:

    * Django 0.96.2
    * Django 0.95.3
    * Django 0.91.2

All users of affected versions of Django are strongly encouraged to apply the
relevant patch or upgrade to the relevant patched release as soon as possible.

Python herd, please bump as necessary

Bumping it won't be as easy as it seems: in 0.96.2 tarball some directories are
missing (like extras, examples). I've filled a bug upstream about that, but it
got closed as WONTFIX: http://code.djangoproject.com/ticket/7273, last comment
from that bug:

So the Django code should come from 0.96.2, and the rest from 0.96.1 or use
0.96.1 tarball with a patch.

Created an attachment (id=154317) [edit]
django-0.96.1-to-0.96.2.ebuild.patch

This is a patch for 0.96.1 ebuild to create 0.96.2: it has both versions in
SRC_URI and uses the missing directories from 0.96.1.

Krzysiek, feel free to commit the attached patch to CVS. Or do you need
additional review?

Done:

Thanks, closing without stabling and GLSA.
