critical Nessus Plugin ID 99695
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities were discovered in Django, a high-level Python web development framework. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2016-9013 Marti Raudsepp reported that a user with a hard-coded password is created when running tests with an Oracle database.

- CVE-2016-9014 Aymeric Augustin discovered that Django does not properly validate the Host header against settings.ALLOWED_HOSTS when the debug setting is enabled. A remote attacker can take advantage of this flaw to perform DNS rebinding attacks.

- CVE-2017-7233 It was discovered that is_safe_url() does not properly handle certain numeric URLs as safe. A remote attacker can take advantage of this flaw to perform XSS attacks or to use a Django server as an open redirect.

- CVE-2017-7234 Phithon from Chaitin Tech discovered an open redirect vulnerability in the django.views.static.serve() view.
Note that this view is not intended for production use.

Solution

Upgrade the python-django packages.

For the stable distribution (jessie), these problems have been fixed in version 1.7.11-1+deb8u2.
