Soumettre #870863: ONLINE_FOOD_ORDER_SYSTEM - Stored XSS Vulnerability in edit_food_items.php v1 Stored XSS

## ONLINE_FOOD_ORDER_SYSTEM - Stored XSS Vulnerability in edit_food_items.php

### Vulnerability Description

A stored Cross-Site Scripting (XSS) vulnerability exists in the `edit_food_items.php` file of the ONLINE_FOOD_ORDER_SYSTEM. The `dname` parameter is directly inserted into the database without any sanitization, and subsequently output to the HTML page without escaping, allowing arbitrary JavaScript execution.

### Impact

An attacker can inject malicious JavaScript code via the `dname` parameter, which gets stored in the database and executed in the browser of any user viewing the affected pages. This can lead to cookie theft and session hijacking.

### Code Analysis

**edit_food_items.php (Lines 130-148):**

```php
if (isset($_GET['submit'])) {
$name = $_GET['dname']; // No sanitization
$price = $_GET['dprice'];
$description = $_GET['ddescription'];

// Directly concatenated into SQL UPDATE
$query = mysqli_query($conn, "UPDATE food set
name='$name', price='$price',
description='$description' where F_ID='$F_ID'");
}

// Output from database directly into HTML without htmlspecialchars()
$query = mysqli_query($conn, "SELECT * FROM food f WHERE ...");
while ($row = mysqli_fetch_array($query)) {
echo "<b><a href='edit_food_items.php?update= {$row['F_ID']}'>"
. "{$row['name']}" // Malicious code rendered directly
. "</a></b>";
}
```

### Payload
