The product does not adequately verify the identity of actors at both ends of a communication channel, or does not adequately ensure the integrity of the channel, in a way that allows the channel to be accessed or influenced by an actor that is not an endpoint.
The product does not encrypt sensitive or critical information before storage or transmission.
The product does not implement a required step in a cryptographic algorithm, resulting in weaker encryption than advertised by the algorithm.
The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product.
