function Get-ESXSpeculativeExecution { <# .SYNOPSIS Get ESXi host mitigation status for Spectre .DESCRIPTION Will validate ESXi host for Spectre/Hypervisor-Assisted Guest Mitigation https://www.vmware.com/security/advisories/VMSA-2018-0004.html https://www.vmware.com/security/advisories/VMSA-2018-0012.1.html https://www.vmware.com/security/advisories/VMSA-2018-0020.html .NOTES File Name : Get-ESXSpeculativeExecution.ps1 Author : Edgar Sanchez - @edmsanchez13 Contributor : Ariel Sanchez - @arielsanchezmor Version : 2.4.7 .Link https://github.com/arielsanchezmora/vDocumentation .INPUTS If inputBiosFile is specified then an offline CSV file path input must be provided to check against BIOS version If inputMcuFile is specified then an offline CSV file path input must be provided to check against MCU revision If UseSSH is specified then SSH will be used to gather details around current MCU revisions. You will be prompted for username and password .OUTPUTS CSV file Excel file .PARAMETER VMhost The name(s) of the vSphere ESXi Host(s) .EXAMPLE Get-ESXSpeculativeExecution -VMhost devvm001.lab.local .PARAMETER Cluster The name(s) of the vSphere Cluster(s) .EXAMPLE Get-ESXSpeculativeExecution -Cluster production .PARAMETER Datacenter The name(s) of the vSphere Virtual Datacenter(s). .EXAMPLE Get-ESXSpeculativeExecution -datacenter vDC001 .PARAMETER inputBiosFile Specify input CSV file containing BIOS versions to validate against. Use this if you do not have access to the internet or wish to use your own offline version .EXAMPLE Get-ESXSpeculativeExecution -Cluster production -inputBiosFile "c:\temp\BIOSUpdates.csv" .PARAMETER inputMcuFile Specify input CSV file containing Intel MCU version to validate against. Use this if you do not have access to the internet or wish to use your own offline version .EXAMPLE Get-ESXSpeculativeExecution -Cluster production -inputMcuFile "c:\temp\Intel_MCU.csv" .PARAMETER UseSSH Switch to use SSH to gahter specific MCU revisions details from the ESXi host. This needs to be specified if needed and relies on Posh-SSH Module being installed. Posh-SSH Module can be installed directly from the PowerShell Gallery. See https://github.com/darkoperator/Posh-SSH for more information .EXAMPLE Get-ESXSpeculativeExecution -Cluster production -UseSSH .PARAMETER ReportOnVMs Switch to report on virtual machines. This needs to be specified if needed. .EXAMPLE Get-ESXSpeculativeExecution -Cluster production -ReportOnVMS .PARAMETER ExportCSV Switch to export all data to CSV file. File is saved to the current user directory from where the script was executed. Use -folderPath parameter to specify a alternate location .EXAMPLE Get-ESXSpeculativeExecution -Cluster production -ExportCSV .PARAMETER ExportExcel Switch to export all data to Excel file (No need to have Excel Installed). This relies on ImportExcel Module to be installed. ImportExcel Module can be installed directly from the PowerShell Gallery. See https://github.com/dfinke/ImportExcel for more information File is saved to the current user directory from where the script was executed. Use -folderPath parameter to specify a alternate location .EXAMPLE Get-ESXSpeculativeExecution -Cluster production -ExportExcel .PARAMETER folderPath Specify an alternate folder path where the exported data should be saved. .EXAMPLE Get-ESXSpeculativeExecution -Cluster production -ExportExcel -folderPath C:\temp .PARAMETER PassThru Switch to return object to command line .EXAMPLE
