Summary: The recently discovered CVE-2022-4091 vulnerability in SourceCodester Canteen Management System exposes users to critical cross-site scripting (XSS) attacks. This article delves into the details of the vulnerability, demonstrates a potential exploit using a code snippet, and points to original references for further information.

Introduction: The SourceCodester Canteen Management System, a popular software solution for efficient management of canteens and cafeteria operations, has unfortunately been found to contain a problematic vulnerability (CVE-2022-4091). This cross-site scripting (XSS) vulnerability resides within the 'food.php' file and is caused by improper handling of the 'product_name' argument by the 'query' function. An attacker can exploit this vulnerability remotely to execute malicious scripts which, in turn, can lead to the unintended disclosure of sensitive user information or unauthorized access to the system.

Exploit Details: CVE-2022-4091 allows potential attackers to manipulate the 'product_name' argument in 'food.php' to inject malicious payloads. The underlying issue is that this argument is not properly sanitized, hence allowing for malicious scripts to be executed in the context of the user's browser.

A typical cross-site scripting attack using this vulnerability might look like the following code snippet:

http://<target>/food.php?product_name=<script>alert('XSS');</script>;

In the above example, the attacker injects a simple script to display an alert box containing 'XSS'. In a real attack scenario, the attacker may use more sophisticated scripts for various purposes such as stealing session cookies or redirecting the user to a phishing site by modifying the DOM.
