A Missing Authorization Vulnerability (CVE-2023-32299) has been identified in the popular Anzia Ni WooCommerce Sales Report plugin which could allow unauthorized users to exploit incorrectly configured access control security levels. This issue affects Ni WooCommerce Sales Report versions from n/a through 3.7.3. In this post, we will discuss the details of the vulnerability, its impact, and suggested mitigations.

Vulnerability Details

Ni WooCommerce Sales Report is a widely-used plugin that offers WooCommerce shop owners detailed analytics of their e-commerce sales. The vulnerability in question stems from improper access control checks on certain administrative functions of the plugin, allowing attackers to potentially conduct privilege escalation attacks and gain unauthorized access to sensitive data.

The vulnerable code snippet in the plugin is shown below

// File: ni-woocommerce-class-sales-report.php, Line 123
function check_nonce_and_user_permission() {
    if (!isset($_REQUEST['_wpnonce']) || 
        !wp_verify_nonce($_REQUEST['_wpnonce'], 'admin_nonce')) {
        // Missing nonce or invalid, deny access
        die('Nonce check failed.');
    }
}

As seen in the code snippet, the plugin uses WordPress nonces for access control. However, it fails to implement proper authorization checks for user capabilities or roles, which leads to the vulnerability.

Exploiting the Vulnerability

An attacker can create a malicious link containing the vulnerable URL and trick an authorized user into clicking it. This can lead to unauthorized access to privileged actions such as adding, modifying, or deleting reports. A sample URL exploiting the vulnerability could look like this:

http://example.com/wp-admin/admin-ajax.php?action=ni_woo_sales_report&function=get_report_data&_wpnonce=[valid_admin_nonce]

Alternatively, an attacker can leverage automated tools to exploit the vulnerability and gain unauthorized access to the backend.
