NVD Description
Note: Versions mentioned in the description apply only to the upstream python-django
package and not the python-django
package as distributed by Ubuntu
.
See How to fix?
for Ubuntu:16.04
relevant fixed versions and status.
Django 1.10 before 1.10.7, 1.9 before 1.9.13, and 1.8 before 1.8.18 relies on user input in some cases 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 "safe" when they shouldn't be, aka an open redirect vulnerability. 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.
