CVE-2023-45828 - Missing Authorization Vulnerabilities in RumbleTalk Live Group Chat Allow Exploitation of Incorrectly Configured Access Control Security Levels

A critical vulnerability in RumbleTalk Ltd's RumbleTalk Live Group Chat has been identified as CVE-2023-45828. This vulnerability is a security flaw that results from missing authorization while designing the access control strategy, enabling unauthorized users to exploit the application. In RumbleTalk Live Group Chat versions up to 6.2.5, attackers can exploit this vulnerability to access valuable information and perform malicious activities, compromising the security of the system and its users.

Impact

The severity of this vulnerability is high. Attackers can exploit this flaw to execute various harmful activities on the application, such as reading and writing sensitive data. This vulnerability is present in RumbleTalk Ltd's RumbleTalk Live Group Chat software and can be exploited remotely by exploiting incorrectly configured access control security levels.

Details

The vulnerability is caused by missing authorization in the access control mechanism. An attacker with minimal knowledge of the application can detect this security flaw and exploit it to gain unauthorized access to the system. To illustrate the issue, here is a sample code snippet assuming a chat feature:

def access_chat(chat_id, user_id):
    # Missing authorization check (user_id is not checked for authorization)
    return get_chat_content(chat_id)

In the code above, the access_chat function does not properly verify if the user_id has the authorization to access the chat_id. As a result, an attacker can pass any arbitrary chat_id to gain unauthorized access to the chat content.

Exploitation

To exploit this vulnerability, an attacker must send a specifically crafted request to RumbleTalk Live Group Chat's software, including malicious parameters or payloads designed to bypass access control security levels. Given that the application's security measures are insufficient, the attacker can execute unauthorized actions, access restricted areas, or deactivate security features.

For more details, please refer to the National Vulnerability Database (NVD) and the Original Advisory from RumbleTalk Ltd.
