Vulnerability discussion

Ensure that no device is connected to a virtual machine if it is not required. For example, floppy, serial and parallel ports are rarely used for virtual machines in a datacenter environment, and CD/DVD drives are usually connected only temporarily during software installation.

Check content

From the vSphere Client select the Virtual Machine right click and go to Edit Settings. Review the VMs hardware and verify no CD/DVD drives are connected. or From a PowerCLI command prompt while connected to the ESXi host or vCenter server run the following command: Get-VM | Get-CDDrive | Where {$_.extensiondata.connectable.connected -eq $true} | Select Parent,Name If a virtual machine has a CD/DVD drive connected other than temporarily, this is a finding.

Fix text

From the vSphere Client select the Virtual Machine right click and go to Edit Settings. Select the CD/DVD drive and uncheck "Connected" and "Connect at power on" and remove any attached ISOs. or From a PowerCLI command prompt while connected to the ESXi host or vCenter server run the following command: Get-VM "VM Name" | Get-CDDrive | Set-CDDrive -NoMedia
