A critical vulnerability (CVE-2024-1972) has been identified in the SourceCodester Online Job Portal 1., which primarily affects the EditProfile.php file. This vulnerability has been classified as problematic, as it enables attackers to exploit the Address field for Cross-Site Scripting (XSS) purposes. Due to its potentially damaging nature, it's essential to understand how this vulnerability works and what steps can be taken to protect the Online Job Portal from potential attacks.

Description of the vulnerability

The vulnerability in question affects an unknown functionality of the /Employer/EditProfile.php file in the SourceCodester Online Job Portal 1.. Attackers can manipulate the Address argument within the file, which leads to Cross-Site Scripting (XSS). This means that malicious actors can inject client-side scripts into web pages viewed by other users, possibly giving them unauthorized access to sensitive information.

As the vulnerability can be exploited remotely, it poses a significant risk to the integrity of the Online Job Portal. The exploit has already been disclosed to the public and is therefore more likely to be used by attackers.

Exploit details

The vulnerability has been given the identifier VDB-255128. To exploit it, an attacker can manipulate the Address argument within the /Employer/EditProfile.php file to execute client-side scripts. Here is a code snippet demonstrating this vulnerability:

<?php
// ... other code

// Faulty line
$address = $_POST['Address'];

// ... other code

// This line doesn't properly sanitize the $address variable
echo "<input type='text' class='form-control' name='Address' value='".$address."' />";
?>

As you can see, the code doesn't sanitize the user input for the 'Address' field, which enables attackers to insert malicious JavaScript code by manipulating the input field.

- Full technical details of this vulnerability can be found in the CVE-2024-1972 document published by the CVE® Program
- For further information and possible mitigations, you may refer to the VDB-255128 entry at The Exploit Database

Conclusion and recommendations

To protect the Online Job Portal system from potential attacks, developers should identify and fix the vulnerability within the /Employer/EditProfile.php file. This may involve sanitizing user input to ensure that no malicious scripts can be executed via the Address field. It is also important to stay informed about any new exploits and vulnerabilities that may affect the portal's security.
