What is CVE-2017-7233?
CVE-2017-7233 is a medium-severity vulnerability in Djangoproject Django, published on 4 Apr 2017. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
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.
Weakness: CWE-601
