Description
If SNMP is not being used, it must remain disabled. If it is being used, the proper trap destination must be configured. If SNMP is not properly configured, monitoring information can be sent to a malicious host that can use this information to plan an attack.
ℹ️ Check
From an ESXi shell, run the following command:
# esxcli system snmp get
or
From a PowerCLI command prompt while connected to the ESXi host, run the following command:
Get-VMHostSnmp | Select *
If SNMP is not in use and is enabled, this is a finding.
If SNMP is enabled and is not using v3 targets with authentication, this is a finding.
Note: SNMP v3 targets can only be viewed and configured via the "esxcli" command.
✔️ Fix
To disable SNMP from an ESXi shell, run the following command:
# esxcli system snmp set -e no
or
From a PowerCLI command prompt while connected to the ESXi Host:
Get-VMHostSnmp | Set-VMHostSnmp -Enabled $false
