Description Adam Mariš 2017-03-29 20:36:33 UTC 
Django relies on user input in some cases (e.g. django.contrib.auth.views.login() and i18n to redirect the user to an "on success" URL. The security check for these redirects (namely django.utils.http.is_safe_url()) considered some numeric URLs (e.g. http:999999999) "safe" when they shouldn't be.

Also, if a developer relies on is_safe_url() to provide safe redirect targets and puts such a URL into a link, they could suffer from an XSS attack.

Affected versions:
* Django master development branch
* Django 1.11 (currently at release candidate status)
* Django 1.10
* Django 1.9
* Django 1.8

Statement:

This issue affects the versions of python-django as shipped with Red Hat Satellite 6. Please note that python-django, as used by Pulp does not make use of the Pulp doesn't use "is_safe_url" directly or the "i18n" views or the "django.contrib.auth" Login view. Red Hat Product Security has rated this issue as having Low security impact. A future update may address this issue.
