An issue was discovered in ThingsBoard 3.4.1, allows low privileged attackers (CUSTOMER_USER) to gain escalated privileges (vertically) and become an Administrator (TENANT_ADMIN) or (SYS_ADMIN) on the web application. It is important to note that in order to accomplish this, the attacker must know the corresponding API's parameter (authority : value).
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
