+
+Django released a security update on July 4, 2022, which fixes a SQL injection vulnerability in the Trunc() and Extract() database functions. This vulnerability affects Django versions before 4.0.6, 3.2.14.

+
+## Environment Setup
+
+Execute the following command to start a vulnerable Django 4.0.5 server:
+
+```
+docker compose up -d
+```
+
+After the server is started, you can access the web page at `http://your-ip:8000`.
+
+## Vulnerability Reproduction
+
+The web application uses the `Trunc` function to aggregate page click counts by datetime. Visit `http://your-ip:8000/?date=minute` to see the number of clicks per minute:

+
+To exploit the SQL injection vulnerability, modify the `date` parameter with malicious input:
+
+```
+http://your-ip:8000/?date=xxxx'xxxx
+```
+
+The SQL error message will be displayed, confirming the successful injection:
