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

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
