Background
python-django is a popular web framework for building web applications using the Python programming language. It provides a robust set of tools and features for developing secure and scalable web applications. However, a vulnerability has been discovered in python-django versions before 1.8.15 and 1.9.x before 1.9.10. This vulnerability allows remote attackers to bypass the Cross-Site Request Forgery (CSRF) protection mechanism by setting arbitrary cookies. This can lead to unauthorized access and potential security breaches.
Vulnerability Detail
The vulnerability arises from the cookie parsing code in python-django. When used on a site with Google Analytics, an attacker can exploit this vulnerability by setting arbitrary cookies. By doing so, they can bypass the intended CSRF protection mechanism, which is designed to prevent unauthorized actions on behalf of a user. This vulnerability can be exploited remotely, allowing attackers to perform actions on behalf of unsuspecting users without their consent or knowledge.
