Vulnerability Type
Stored Cross-Site Scripting (Stored XSS)

CWE

CWE-79 – Improper Neutralization of Input During Web Page Generation (Cross-Site Scripting)

Severity
Medium

Description
The Online Food Ordering System in PHP 1.0 is vulnerable to a Stored Cross-Site Scripting (XSS) vulnerability in the cuisines parameter processed by the /dbfood/food.php endpoint. The vulnerability exists because the application does not properly sanitize or encode user-controlled input before storing it in the database and rendering it within the web interface.

The food management functionality allows administrators to add new food items by submitting parameters such as food_name, cost, cuisines, payment options (chk[]), and an image file (food_pic). The value supplied in the cuisines field is stored in the backend database and later displayed within the application interface without proper output encoding.

An attacker can exploit this vulnerability by injecting malicious JavaScript code into the cuisines parameter during the food creation process. Because the application stores the input and later displays it without proper sanitization, the malicious payload becomes persistent and executes whenever the stored food item is viewed.

For example, an attacker can inject a payload such as <details/open/ontoggle=prompt(origin)> in the cuisines field. Once the food item is stored, the malicious script executes automatically when the food listing page or related interface renders the stored value.

Successful exploitation allows attackers to execute arbitrary JavaScript within the context of the application. This may enable attackers to hijack authenticated sessions, steal cookies, perform actions on behalf of administrators, or inject malicious content into the application interface.

Root Cause
The vulnerability occurs due to improper handling of user-supplied input within the application. The cuisines field accepts arbitrary user input and stores it directly in the database without performing adequate validation or sanitization.

When the stored data is later displayed on application pages, the system renders the value directly into the HTML response without applying output encoding. Because of this, malicious HTML or JavaScript code embedded in the stored value is interpreted and executed by the browser.

This issue arises from:

Lack of input validation for the cuisines parameter

Absence of output encoding before rendering stored user input

Direct insertion of stored database values into HTML content

Affected Endpoint
/dbfood/food.php

Vulnerable Parameter
cuisines

Proof of Concept
The vulnerability can be triggered using the following HTTP request:

Steps to Reproduce
Install and run the Online Food Ordering System in PHP.

Navigate to the food management or food creation page.

Intercept the request using a proxy tool such as Burp Suite.

Insert the following payload into the cuisines parameter:

<details/open/ontoggle=prompt(origin)>

Submit the request to create the food item.

Navigate to the page where the food item is displayed.

Result
When the stored food entry is viewed within the application interface, the injected JavaScript payload executes automatically in the browser of the user viewing the page. This confirms the presence of a Stored Cross-Site Scripting vulnerability.

Impact
An attacker exploiting this vulnerability may be able to:

Execute arbitrary JavaScript in victim browsers

Hijack administrator or user sessions

Steal authentication cookies

Perform unauthorized actions within the application

Inject malicious content into the application interface

Because the payload is stored in the database, it may affect all users who access the affected page.

Remediation
Developers should implement the following security measures:

Output Encoding

Encode user-controlled input before rendering it in HTML responses.
