Question 106

The results of an Nmap scan are as follows: Which of the following would be the BEST conclusion about this device?

  1. This device may be vulnerable to the Heartbleed bug due to the way transactions over TCP/22 handle heartbeat extension packets, allowing attackers to obtain sensitive information from process memory.
  2. This device is most likely a gateway with in-band management services.
  3. This device is most likely a proxy server forwarding requests over TCP/443.
  4. This device may be vulnerable to remote code execution because of a buffer overflow vulnerability in the method used to extract DNS names from packets prior to DNSSEC validation.
