    Affected Products

    Product | Affected Versions

    messageformat | < 2.3.0 How the Exploit Works

    The vulnerability arises from the package’s improper handling of message key paths when processing nested message keys containing special characters such as __proto__. This can lead to unintended modification of the JavaScript Object prototype, a phenomenon known as prototype pollution. A remote attacker can take advantage of this flaw to inject properties into the global object prototype via specially crafted message input, creating potential for denial of service attacks or other undefined behaviors.

    Conceptual Example Code

    Below is a conceptual example demonstrating how the vulnerability might be exploited:

    let malicious_payload = {
    "__proto__.polluted": "Prototype polluted!"
    };
    messageformat.format(malicious_payload);

    Following execution of the above code, all objects in the affected JavaScript context will have a “polluted” property with the value “Prototype polluted!”. This could be used to manipulate or disrupt the normal operation of the application.

    How the Exploit Works

    The exploit works by an attacker injecting properties into Object.prototype via a carefully crafted payload. This payload can be delivered through network interaction with the application using the vulnerable package. The injection can modify the core behavior of the application, causing it to crash (Denial of Service) or behave unpredictably, potentially leading to system compromise or data leakage.

    Conceptual Example Code

    Here is a conceptual example of a malicious payload that could exploit this vulnerability:

    POST /web3/subscribe HTTP/1.1
    Host: target.example.com
    Content-Type: application/json
    {
    "__proto__": {
    "shutdown": true
    }
    }

    In this example, if the server parses this JSON and merges it into their application state, it could trigger unwanted behavior like shutting down the system or service. Please note that this is a simplified example and real exploit code may be more complex and less obvious.
