How the Exploit Works

The vulnerability in Valtimo allows unauthorized users to access and manipulate objects on the platform. This is due to a flaw in the security configuration of the platform, which allows all objects for which an object-management configuration exists to be listed, viewed, edited, created or deleted by unauthorised users. If the URLs of these objects are exposed via other channels, the contents of these objects can be viewed independent of their object-management configurations.

Conceptual Example Code

The following conceptual example demonstrates how an attacker might exploit this vulnerability. This might involve sending a malicious HTTP request to a vulnerable endpoint:

GET /object-management/api/objects/ HTTP/1.1
Host: target.example.com
Content-Type: application/json

In this example, the attacker sends a GET request to the object-management endpoint, potentially allowing them to list all objects for which an object-management configuration exists. With this information, they could then proceed to view, edit, create, or delete these objects without authorization.
