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.
The snmp-info script only returns detailed system information when it successfully queries the device using a valid readâonly community string. Because the banner explicitly shows "SNMPv2c server (public)", you know the default community string "public" is accepted. This means you can perform unauthenticated SNMP walks to extract additional data such as running processes, network interfaces, user accounts, and potentially software versions. The result says nothing about NetBIOS, SMB vulnerabilities, or SNMPv3 security, so those answers are incorrect.
