Arch Linux Security Advisory ASA-202107-11
==========================================

Severity: High
Date    : 2021-07-03
CVE-ID  : CVE-2021-35042
Package : python-django
Type    : insufficient validation
Remote  : Yes
Link    : https://security.archlinux.org/AVG-2123

Summary
=======

The package python-django before version 3.2.5-1 is vulnerable to
insufficient validation.

Resolution
==========

Upgrade to 3.2.5-1.

# pacman -Syu "python-django>=3.2.5-1"

The problem has been fixed upstream in version 3.2.5.

Workaround
==========

None.

Description
===========

A security issue has been found in Django before version 3.2.5.
Unsanitized user input passed to QuerySet.order_by() could bypass
intended column reference validation in path marked for deprecation
resulting in a potential SQL injection even if a deprecation warning is
emitted. As a mitigation the strict column reference validation was
restored for the duration of the deprecation period.

Impact
======

A remote attacker is able to perform a SQL injection via unsanitized
user input passed to QuerySet.order_by().
