In this post, we will explore the cross-site scripting (XSS) vulnerability identified as CVE-2024-25344. This vulnerability affects several components of ITFlow.org before commit v.432488eca3998c5be6b6b9e8f8ba01f54bc12378 and allows a remote attacker to execute arbitrary code and obtain sensitive information. We will discuss the affected components, provide a code snippet demonstrating the vulnerability, delve into the exploit details, and suggest preventive steps.

settings_mail.php

These files are responsible for various application settings and configurations within ITFlow.org.

This code snippet demonstrates the XSS vulnerability

<?php
  ...
  $instance = $_REQUEST['instance'];
  // Vulnerable line: No escaping or filtering performed on user-supplied data.
  echo "<input type='hidden' name='instance' value='$instance'>";
  ...
?>

In this example, an attacker can inject malicious code by crafting a URL with the payload as the value of the "instance" parameter, such as http://vulnerable.site/settings.php?instance=<script>alert(1)</script>;.

Prevention Measures

To mitigate the risk of this vulnerability, developers should implement the following preventive steps:

1. Use the latest version of ITFlow.org, which includes the commit fixing the vulnerability: v.432488eca3998c5be6b6b9e8f8ba01f54bc12378.
2. Employ input validation and output encoding techniques to filter out malicious payloads before displaying data to users.
