1. A method for analyzing vulnerability of a pass-through network device under analysis (DUA) to protocol abuse of a network communications protocol, the method comprising:

  • establishing a network connection for the sending of messages from a sender through the pass-through network DUA to a receiver, the single software application acting as both the sender and the receiver, making a TCP connection through the pass-through network DUA with the source and destination of the TCP connection controlled by the single software applicationsending multiple test messages from the from the sender port to the receiver probing vulnerability of the pass-through network DUA to protocol abuse of the network communications protocol;

    receiving multiple response messages corresponding to the test messages; and

    determining whether the pass-through network DUA has vulnerabilities by analyzing the sent test messages and the corresponding received response messages.
