Vulnerability Details

The missing authorization vulnerability in the Product Recommendation Quiz plugin for eCommerce platforms, such as Shopify, results from a lack of proper access control configurations on quiz-related actions. Consequently, this permits threat actors to retrieve sensitive information or perform malicious activities, like modifying quiz content unlawfully. The vulnerability affects eCommerce store owners who have installed and run Product Recommendation Quiz versions from n/a through 2.1.2.

Affected Versions: Product Recommendation Quiz for eCommerce from n/a through 2.1.2

Exploit Details

Threat actors can exploit this missing authorization vulnerability by sending crafted HTTP requests to the application endpoints responsible for handling quiz data. The following code snippet exemplifies an HTTP request that would exploit the vulnerability:

import requests

url = "https://target_ecommerce_store/quiz_endpoint";
headers = { "Content-Type": "application/json" }
data = {
    "action": "malicious_action",
    # further details to exploit the vulnerability
}

response = requests.post(url, headers=headers, json=data)
print(response.text)

By sending this HTTP request, an attacker could potentially gain unauthorized access to quiz data, modify the content, or even delete the entire quiz.
