Arch Linux: ASA-201602-1 Medium Severity: Bypass Permissions in Django

Arch Linux Security Advisory ASA-201602-1
========================================
Severity: Medium
Date    : 2016-02-02
CVE-ID  : CVE-2016-2048
Package : python-django
Type    : permission bypass
Remote  : Yes
Link    : https://wiki.archlinux.org/title/CVE

Summary
======
The package python-django before version 1.9.2-1 is vulnerable to
permission bypass.

Resolution
=========
Upgrade to 1.9.2-1.

# pacman -Syu "python-django>=1.9.2-1"

The problem has been fixed upstream in version 1.9.2.

Workaround
=========
None.

Description
==========
If a ModelAdmin uses save_as=True (not the default), the admin provides an
option when editing objects to "Save as new".  A regression in Django 1.9
prevented that form submission from raising a "Permission Denied" error for
users without the "add" permission.

Impact
=====
A remote attacker with django User account and change permissions but not
"add" might be able to create objects for ModelAdmin with save=True.
