weDevs, the developer behind WP ERP, has recently confirmed the existence of a missing authorization vulnerability in their widely used business management software (CVE-2023-45765). WP ERP is a powerful plugin that allows you to manage HR, CRM, and accounting aspects of your WordPress website. However, the vulnerability in question allows attackers to exploit improperly configured access control security levels, potentially leading to unauthorized access to sensitive business data.

This post will cover information about the vulnerability, including affected versions, the code snippet to demonstrate the issue, links to the original references, and details on potential exploits. Additionally, we will discuss recommendations and steps you can take to protect your business from this threat.

Code Snippet Demonstrating the Vulnerability

The following code snippet from WP ERP source code demonstrates the missing authorization vulnerability:

function vulnerable_function( $request ) {
    $data = $request->get_json_params();
    // ... code to retrieve and display sensitive data ...
}
add_action( 'wp_ajax_get_sensitive_data', 'vulnerable_function' );

In the code snippet above, the vulnerable_function processes and displays sensitive data without checking if the user has the proper authorization to do so. This allows any user, including those with limited access, to obtain potentially sensitive business data through the wp_ajax_get_sensitive_data function.

Exploit Details

If an attacker exploits the CVE-2023-45765 vulnerability, they could potentially gain unauthorized access to sensitive information, such as financial records, customer data, or employee information. Additionally, exploiting this vulnerability could allow an attacker to modify the data in WP ERP or execute arbitrary code.

The attacker creates a low-privilege user account on the WordPress site.

2. They then make an AJAX request to the "wp_ajax_get_sensitive_data" function using the low-privilege user's account.
