One specific condition which may be rather rare (and therefore render most applications non-exploitable in practice) is the existence of Spring endpoints which bind request parameters to a non-primitive (Java Bean) type.

Einen Schwachpunkt hat dieser Ansatz aber: Der Ausgangspunkt von einer BITB-Attacke ist eine Phishing-Website, die das OAuth-Anmeldeverfahren mit dem Fake-Fenster anbietet.
