Debian DLA-1842-1 : python-django security update

medium Nessus Plugin ID 126390

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that the Django Python web development framework did not correct identify HTTP connections when a reverse proxy connected via HTTPS.

When deployed behind a reverse-proxy connecting to Django via HTTPS django.http.HttpRequest.scheme would incorrectly detect client requests made via HTTP as using HTTPS. This resulted in incorrect results for is_secure(), and build_absolute_uri(), and that HTTP requests would not be redirected to HTTPS in accordance with SECURE_SSL_REDIRECT.

HttpRequest.scheme now respects SECURE_PROXY_SSL_HEADER, if it is configured, and the appropriate header is set on the request, for both HTTP and HTTPS requests.

If you deploy Django behind a reverse-proxy that forwards HTTP requests, and that connects to Django via HTTPS, be sure to verify that your application correctly handles code paths relying on scheme, is_secure(), build_absolute_uri(), and SECURE_SSL_REDIRECT.

For Debian 8 'Jessie', this issue has been fixed in python-django version 1.7.11-1+deb8u6.

We recommend that you upgrade your python-django packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
