[Security] Bump django from 1.9 to 2.1.4

[dependabot-preview]

Bumps django from 1.9 to 2.1.4. This update includes security fixes.

Vulnerabilities fixed

Sourced from The Sonatype OSS Index.

[CVE-2016-9013] null
Django 1.8.x before 1.8.16, 1.9.x before 1.9.11, and 1.10.x before 1.10.3 use a hardcoded password for a temporary database user created when running tests with an Oracle database, which makes it easier for remote attackers to obtain access to the database server by leveraging failure to manually specify a password in the database settings TEST dictionary.

Affected versions: <= 1.8.15, >= 1.8.0; <= 1.9.10, >= 1.9.0; <= 1.10.2, >= 1.10.0

Sourced from The Sonatype OSS Index.

[CVE-2016-7401] null
The cookie parsing code in Django before 1.8.15 and 1.9.x before 1.9.10, when used on a site with Google Analytics, allows remote attackers to bypass an intended CSRF protection mechanism by setting arbitrary cookies.

Affected versions: <= 1.8.14; <= 1.9.9, >= 1.9.0

[CVE-2016-2512] Improper Neutralization of Input During Web Page Generation ("Cross-site Scripting")
The utils.http.is_safe_url function in Django before 1.8.10 and 1.9.x before 1.9.3 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks or possibly conduct cross-site scripting (XSS) attacks via a URL containing basic authentication, as demonstrated by http://mysite.example.com\[**attacker**](https://github.com/attacker).com.

Affected versions: = 1.8.9; <= 1.9.2, >= 1.9.0

Sourced from The Sonatype OSS Index.

[CVE-2017-7233] URL Redirection to Untrusted Site ("Open Redirect")
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.

Affected versions: = 1.8.0-a1; <= 1.8.0-b2, >= 1.8.0-b1; = 1.8.0; = 1.8.0-c1; <= 1.8.17, >= 1.8.1; = 1.9.0-a1; = 1.9.0-b1; <= 1.9.0-rc2, >= 1.9.0-rc1; <= 1.9.12, >= 1.9.0; = 1.10.0-a1; = 1.10.0-b1; = 1.10.0-rc1; <= 1.10.6, >= 1.10.0

Sourced from The Sonatype OSS Index.

[CVE-2016-2048] Improper Access Control
Django 1.9.x before 1.9.2, when ModelAdmin.save_as is set to True, allows remote authenticated users to bypass intended access restrictions and create ModelAdmin objects via the "Save as New" option when editing objects and leveraging the "change" permission.

Affected versions: <= 1.9.1, >= 1.9.0

Sourced from The Sonatype OSS Index.

[CVE-2017-7234] URL Redirection to Untrusted Site ("Open Redirect")
A maliciously crafted URL to a Django (1.10 before 1.10.7, 1.9 before 1.9.13, and 1.8 before 1.8.18) site using the django.views.static.serve() view could redirect to any other domain, aka an open redirect vulnerability.

Affected versions: = 1.8.0-a1; <= 1.8.0-b2, >= 1.8.0-b1; = 1.8.0; = 1.8.0-c1; <= 1.8.17, >= 1.8.1; = 1.9.0-a1; = 1.9.0-b1; <= 1.9.0-rc2, >= 1.9.0-rc1; <= 1.9.12, >= 1.9.0; = 1.10.0-a1; = 1.10.0-b1; = 1.10.0-rc1; <= 1.10.6, >= 1.10.0

Sourced from The Sonatype OSS Index.

[CVE-2016-9014] Permissions, Privileges, and Access Controls
Django before 1.8.x before 1.8.16, 1.9.x before 1.9.11, and 1.10.x before 1.10.3, when settings.DEBUG is True, allow remote attackers to conduct DNS rebinding attacks by leveraging failure to validate the HTTP Host header against settings.ALLOWED_HOSTS.

Affected versions: <= 1.8.15, >= 1.8.0; <= 1.9.10, >= 1.9.0; <= 1.10.2, >= 1.10.0

Sourced from The Sonatype OSS Index.

[CVE-2016-6186] Improper Neutralization of Input During Web Page Generation ("Cross-site Scripting")
Cross-site scripting (XSS) vulnerability in the dismissChangeRelatedObjectPopup function in contrib/admin/static/admin/js/admin/RelatedObjectLookups.js in Django before 1.8.14, 1.9.x before 1.9.8, and 1.10.x before 1.10rc1 allows remote attackers to inject arbitrary web script or HTML via vectors involving unsafe usage of Element.innerHTML.

Affected versions: <= 1.8.13; = 1.9.0-rc1; <= 1.9.7, >= 1.9.0; = 1.10.0-alpha1; = 1.10.0-beta1

Sourced from The Sonatype OSS Index.

[CVE-2016-2513] Information Exposure
The password hasher in contrib/auth/hashers.py in Django before 1.8.10 and 1.9.x before 1.9.3 allows remote attackers to enumerate users via a timing attack involving login requests.

Affected versions: = 1.8.9; <= 1.9.2, >= 1.9.0
