CVE-2023-2100: SourceCodester Vehicle Service Management System Cross-Site Scripting Vulnerability

A new vulnerability (CVE-2023-2100) has been discovered in the SourceCodester Vehicle Service Management System 1., a widely used tool in the management of vehicle services. The vulnerability has been classified as problematic and puts users at risk of a cross-site scripting (XSS) attack.

The Vulnerability

The vulnerability resides in an unspecified code portion of the file '/admin/report/index.php' within the SourceCodester Vehicle Service Management System. Attackers can manipulate the 'date_end' argument, leading to a cross-site scripting attack. Such an attack may lead to unauthorized access to sensitive data, session hijacking, or defacement of web content, putting users at risk.

This attack can be initiated remotely, and the exploit has already been disclosed to the public. Consequently, the vulnerability must be given immediate attention to avoid any potential damage.

Here is a code snippet showcasing the exploit

// Vulnerable file: /admin/report/index.php
$date_end = $_GET['date_end'];
...
echo " <h2 align='centre'> Report generated for period ending: " . $date_end . "</h2>";

As can be seen, the variable $date_end is being directly taken from user input ($_GET variable), then echoed without any proper input validation or output encoding.

Exploit Details

To exploit the vulnerability, an attacker can send a crafted URL containing malicious content as the 'date_end' argument value. Below is an example of a malicious link:

http://example.com/admin/report/index.php?date_end=<script>alert("XSS")</script>;

When an unsuspecting user follows this link, the attacker's script will execute, resulting in an XSS attack.
