Summary: A recent vulnerability discovered in SourceCodester Online Job Portal 1. has been recognized as problematic, exposing sensitive information to cross site scripting attacks. An immediate resolution is necessary to mitigate this threat.

Introduction

The world of online job portals has vastly expanded in recent years, with more and more businesses and individuals relying on these platforms to connect employers and job seekers. The efficient and secure handling of user data has never been more important. Unfortunately, a worrying vulnerability has recently been found in SourceCodester Online Job Portal 1..

This vulnerability, identified as *CVE-2024-1922*, is classified as problematic – meaning it can cause significant harm to users, and even compromise the entire system. It exploits an unknown functionality of the file /Employer/ManageJob.php, a component of the Manage Job Page. The vulnerability is capable of manipulation of the argument "Qualification/Description", and its exploitation would result in a cross site scripting attack that could be remotely launched.

The vulnerability has been disclosed to the public and assigned the identifier VDB-254857. In this post, we will provide more details about this vulnerability, discuss the code snippets responsible for it, and delve into its potential impact.

Examining the Code Snippet

Below is the code snippet from /Employer/ManageJob.php where the vulnerability arises. The manipulation of the "Qualification/Description" argument is responsible for this vulnerability, as it permits untrusted user input to be rendered as HTML content:

// vulnerable code snippet found in /Employer/ManageJob.php
<div class="col-md-12">
    <td><?php echo $row['Qualification']; ?></td>
    <td><?php echo $row['Description']; ?></td>
</div>

As this code does not sanitize the user input, any user-submitted data could be exploited as an XSS (Cross Site Scripting) attack.

The Exploit Details

Exploiting this vulnerability involves manipulating the "Qualification/Description" argument by injecting malicious scripts through untrusted user input. Since there is no sanitization of user input, these scripts can be used to attack other users. The attack can be launched remotely, making it even more threatening.

If an attacker successfully injects a malicious script into the "Qualification/Description" argument, they could potentially:

- Steal sensitive user information, such as authentication credentials, personal information, and browsing history
- Perform actions on a user’s behalf without their knowledge or consent, including making changes to account settings and data
