Certified Ethical Hacker (CEH) Practice Question

While monitoring a Telnet session during a penetration test, you capture a few packets just long enough to determine the server's next TCP sequence number. You immediately forge and transmit a single packet that spoofs the client's address and contains a malicious command, relying on the predicted sequence so the server accepts the data even though you cannot see any subsequent responses. Which attack technique does this illustrate?

  • SSL stripping downgrade attack

  • Man-in-the-middle via ARP spoofing

  • Web application session fixation

  • TCP sequence-prediction (TCP hijacking) attack
