A new security vulnerability (CVE-2023-4555) has been discovered in the SourceCodester Inventory Management System 1. that has been assigned the identifier VDB-238153 and classified as problematic. The vulnerability affects an unknown functionality of the file suppliar_data.php. A remote attacker can exploit this vulnerability by manipulating the 'name' or 'company' argument, leading to cross-site scripting (XSS) attacks. The exploit details have been publicly disclosed and may be used by malicious actors.

Here is a code snippet highlighting the vulnerable part of the code in the suppliar_data.php file

<?php
$company = $_GET['company'];
$name = $_GET['name']; 
?>
<html>
<head>
...
<script>
...
document.getElementById('company').value = "<?php echo $company ?>";
document.getElementById('name').value = "<?php echo $name ?>";
...

As you can see, the $company and $name variables are taken directly from the user input without proper sanitization, making them susceptible to XSS attacks.

Exploit Details

To exploit this vulnerability, an attacker can send a specially crafted web link containing malicious JavaScript code to an unsuspecting user or embed malicious code in a page that gets loaded into the vulnerable Inventory Management System. Here's an example of an exploited payload:

https://vulnerable-system.com/suppliar_data.php?company=%3Cscript%3Ealert%28%22XSS%22%29%3C%2Fscript%3E&name=%3Cscript%3Ealert%28%22XSS%22%29%3C%2Fscript%3E

When the user clicks on the link or visits the compromised page, the JavaScript code will execute within their browser, potentially leading to stolen login credentials, unauthorized actions, or other malicious consequences.

- CVE-2023-4555
- VDB-238153

Mitigation

To mitigate this vulnerability, developers of the SourceCodester Inventory Management System should implement proper input validation and sanitization techniques to protect against XSS attacks. This could include encoding special characters, using prepared statements, or implementing security libraries and tools designed to help with input validation.

Users of the Inventory Management System should check for updates from SourceCodester and apply any patches or security fixes provided for this issue.

Conclusion

The CVE-2023-4555 vulnerability in SourceCodester Inventory Management System 1. could have severe consequences if exploited by an attacker. With the exploit details publicly disclosed, it is crucial for developers to patch the vulnerability and for users to apply any available security updates. Always be mindful of suspicious links and follow best practices for secure coding to minimize the risks associated with XSS attacks.
