CVE-2020-7471

This repository provides the environment and POC for CVE-2020-7471 Potential SQL injection via StringAgg(delimiter) vulnerability.

Affected Django versions

• 1.11 to 1.11.28 (exclusive)
• 2.2 to 2.2.10 (exclusive)
• 3.0 to 3.0.3 (exclusive)

Before downloading and using, the following operations are required:

1. Install the vulnerable Django version. I used:

   root@kitploit:~

   pip install django==3.0.2 -i https://pypi.tuna.tsinghua.edu.cn/simple
   

2. Refer to https://www.runoob.com/postgresql/windows-install-postgresql.html to complete the installation of the PostgreSQL database.

3. Create a new database

   root@kitploit:~

   CREATE DATABASE test;
   

4. Modify the database configuration in sqlvul_projects/settings.py. If you used the default configuration (including setting the password to postgres) in the previous step, no configuration changes are needed and you can skip this step.

   root@kitploit:~

   DATABASES = {
       'default': {
           'ENGINE': 'django.db.backends.postgresql',
           'NAME': 'test',         # 数据库名称
           'USER': 'postgres',
           'PASSWORD': 'postgres', # 数据库用户密码
           'HOST': '127.0.0.1',    # 数据库地址
           'PORT': '5432',
       }
   }
   

5. Initialize the data tables via Django

   root@kitploit:~

   python3 manage.py migrate
   python3 manage.py makemigrations vul_app
   python3 manage.py migrate vul_app
   

Then run the POC script CVE-2020-7471.py.
