**BUG_Author:** sageee

**Vendor:** [StudentManage GitHub Repository](https://gitee.com/DayCloud/student-manage)

**Software:** [StudentManage](https://gitee.com/DayCloud/student-manage)

**Vulnerability Url:**
- `/admin/adminScoreUrl`

## Description:

1. **SQL Injection via User Login:**
- In the url `/admin/adminScoreUrl`, the login function does not properly sanitize user input before using it in an SQL query.
- This can be exploited by sending a crafted request to the login endpoint with malicious SQL code.

2. **Exploiting the SQL Injection:**
- By injecting SQL, an attacker can manipulate the SQL query to bypass authentication or extract sensitive information from the database.

3. **Example SQL Injection Payload:**
- The following payload can be used to bypass authentication:
```
http://<target-ip>/StudentManage/adminScoreUrl?query=1' AND (SELECT 4668 FROM (SELECT(SLEEP(5)))Edrf) AND 'CAla'='CAla
```

4. **Requesting the Login Endpoint:**
- Make a request to the login endpoint with the SQL injection payload:
```
http://<target-ip>/StudentManage/adminScoreUrl?query=1
```

5. **Verifying the Exploit:**
- If the injection is successful, Attackers can use tools to read databases
