# Django JSONField/HStoreField SQL Injection (CVE-2019-14234)
|
|
|
|
[中文版本(Chinese version)](README.zh-cn.md)
|
|
|
|
Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design.
|
|
|
|
Django released a security update on August 1, 2019, which fixes a SQL injection vulnerability in the JSONField and HStoreField model fields. This vulnerability affects Django versions before 2.2.4, 2.1.11, and 1.11.23.
|
|
|
|
The vulnerability requires the developer to use JSONField/HStoreField, and the field name of the queryset can be controlled by the user. Django's built-in admin interface is affected by this vulnerability, providing an easy way to demonstrate the issue.

|
## Environment Setup
|
|
|
|
Execute the following command to compile and start a vulnerable Django 2.2.3 server:
|
|
|
|
```
|
|
docker compose build
|
|
docker compose up -d
|
|
```
|
|
|
|
After the server is started, you can access the Django home page at `http://your-ip:8000`.
|
|
|
|
## Vulnerability Reproduction
|
|
|
|
First, log in to the Django admin interface at `http://your-ip:8000/admin/` using the following credentials:
|
|
|
|
- Username: `admin`
|
|
- Password: `a123123123`
|
|
|
|
Navigate to the Collection model's list view at `http://your-ip:8000/admin/vuln/collection/`:
|
|
|
|
|
|
|
|
To exploit the SQL injection vulnerability, add `detail__a'b=123` to the GET parameters, where `detail` is the JSONField:
|
|
|
|
```
|
|
http://your-ip:8000/admin/vuln/collection/?detail__a%27b=123
|
|
```
|
|
|
|
The SQL error message will be displayed, confirming the successful injection:
