Creating HTTP OPTIONS Deny Verb
I have a Powershell script that I have attached to a Kscript as a dependency to check if a Deny Verb exists in IIS, and if not create one. I routinely run PShells scripts this way, and I have had great success with them...but for some reason this one will not run when executed by KACE. If I run this same PShells script/command locally on the Windows machine, it works fine. There's something about the syntax that Kace is not liking - but I'm just not seeing it.
The first part of the function below works fine...it's only the Options portion that just isn't doing anything - specifically the highlighted line
function remediateIIS {
$date = Get-Date -format MMddyyyy
$rootFolder = "C:\inetpub\wwwroot"
$iisstartFile = "C:\inetpub\wwwroot\iisstart.htm"
$FileExists = Test-Path $iisstartFile
$verbExists = Get-WebConfigurationProperty -PSPath 'MACHINE/WEBROOT/APPHOST' -Filter 'system.webServer/security/requestFiltering/verbs' -Name collection | select verb
$iisLog = "C:\Options\AdminScripts\NexposeRemediations\remediateIIS.log"
#Check to see if the default IIS start page is present. If so, rename it
If ($FileExists -eq $True)
{
#-File Found
Add-Content $iisLog "$date : remediateIIS : INFO : $iisstartFile was found. Issuing command to rename it..."
Rename-Item -Path $iisstartFile -NewName "iisstart.htm_NexposeRemediations_$date" -Force
} Else {
#-File NOT Found
Add-Content $iisLog "$date : remediateIIS : INFO : $iisstartFile was NOT found. Doing nothing else..."
}
#Check to see if the OPTIONS verb is present. If not, Create HTTP OPTIONS Deny Verb at root level of IIS
If (Test-Path -Path $rootFolder) {
If ($verbExists -like '*OPTIONS*')
{
#-Verb Found
Add-Content $iisLog "$date : remediateIIS : INFO : HTTP Options Deny Verb was found. Doing nothing else..."
} Else {
#-Verb NOT Found
Add-Content $iisLog "$date : remediateIIS : INFO : HTTP Options Deny Verb was NOT found. Issuing command to create it..."
Set-WebConfigurationProperty -PSPath 'MACHINE/WEBROOT/APPHOST' -Filter 'system.webServer/security/requestFiltering/verbs' -Value @{VERB="OPTIONS";allowed="False"} -Name collection
}
}
}

Hi,
Do you find anything in the script execution logs ?
Which command do you use to call the .ps1 script ?
Do you have kace's replica ? Is it all replicated before executing the script ?
Let us know :)
1. No Kace replicas...
2. Added my PS1 file as a dependency, then called like this: Launch “$(KACE_SYS_DIR)\WindowsPowerShell\v1.0\powershell.exe” with params “-executionpolicy remotesigned -File $(KACE_DEPENDENCY_DIR)\remediateIIS.ps1” I run a ton of PowerShell scripts this way, and they typically work great.
3. Script execution log below...thx for that...I had forgotten to look there... see below

Hi,
For what I can find, it could be related to the fact that the powershell process launched by KACE is in x86 while the module you are using must be under a x64 process.
I am not sure how to proceed to get a x64 Powershell process but it must be depending on the path you are using when you call your script.
You could rather try to use "C:\Windows\Sysnative\WindowsPowerShell\v1.0\powershell.exe" or "C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe" I think.
I also find these :
Scripting : KScript saying that a Powershell is executed successfully, but nothing is changed. (itninja.com) : Last comment is the same answer as me so it should do the trick
How to run PowerShell's 64bit modules using the SMA's Native PowerShell Support (327636) (quest.com) : These also talk about the "sysnative" path.
Let me know, it can be usefull in the future for me as well!
I'm at a loss on this one...
