Man in the Middle attack for QKD?

In an article titled “Can Eve control PerkinElmer actively-quenched single-photon detector?” Vadim Makarov et al. report that thanks to the “strange behavior” found of one of the most often used photon detectors, it is possible for the eavesdropper (Eve) to inject a crafty pulse and fools Bob’s detector by introducing a click of her choice. Eve can now run a man in the middle attack, and when Alice send Bob the list of erroneous polarizations (the “key reconciliation” phase) Eve will be able to recover the key.
I am not sure at this point whether this is just a shortcoming of the particular hardware being used or if this is a pervasive characteristic of the type of circuits used for the detectors. Let’s see.
