On default installs, ImController is located at: 
\\$ComputerName\C$\Windows\Lenovo\ImController\Service\Lenovo.Modern.ImController.exe

Per the article and advisory, versionf of ImController 1.1.20.2 and earlier are vulnerable.

You can query this remotely and interact with the service through PowerShell. Examples below:
#>

## Query a computer for ImController version
$ComputerName = "SomeComputer"

(Get-ItemProperty '\\$ComputerName\C$\Windows\Lenovo\ImController\Service\Lenovo.Modern.ImController.exe').VersionInfo

<#
Returned data:

ProductVersion   FileVersion      FileName
--------------   -----------      --------
1.1.20.3         1.1.20.3         \\$ComputerName\C$\Windows\Lenovo\ImController\Service\Lenovo.Modern.ImController.exe
#>

## Per the Lenovo advisory article (see CONTEXT at top): 
## "The Lenovo IMController software component is automatically updated by the Lenovo System Interface Foundation Service. 
## To immediately start the update process, reboot the computer or restart the "System Interface Foundation Service" service."
## 
## Personally, I was able to restart the service - no system reboot - and the software updated automatically. 

# Check service
Invoke-Command -ComputerName $ComputerName {Get-Service -DisplayName "System Interface Foundation Service"}

# Restart service
Invoke-Command -ComputerName $ComputerName {Get-Service -DisplayName "System Interface Foundation Service" | Restart-Service}
