In Eclipse Mnestix Browser versions 1.2.0 up until but excluding 2.3.0 it was possible for an unauthenticated attacker to perform actions that are only allowed to be executed by an authorized Mnestix user, like changing the Infrastructure settings or calling the connected and authenticated Mnestix AAS Generator backend.
