Certified Ethical Hacker (CEH) Practice Question

During an internal assessment, you run the command nmap -sU -p 161 --script snmp-info 10.10.1.50 and receive the output: "SNMPv2c server (public): VMware ESXi 6.7.0 build-17167734". Which enumeration conclusion can you confidently make from this result to assist your subsequent attack planning?

  • The host is vulnerable to EternalBlue (MS17-010) because it is running SMB version 1.

  • NetBIOS NULL sessions are enabled, allowing share and user enumeration over TCP port 139.

  • The device accepts the default SNMP community string "public", so you can issue further unauthenticated SNMP queries for more detailed information.

  • SNMPv3 authentication and privacy are enforced, requiring a dictionary attack against user credentials before any data can be read.
