python
# PowerShell script to check for unquoted service paths and demonstrate the vulnerability concept # Function to check for unquoted service paths function Get-UnquotedServicePaths { Write-Host "[*] Checking for unquoted service paths..." $services = Get-WmiObject -Class Win32_Service | Where-Object { $_.PathName -notlike '"*"' -and $_.PathName -like '* *' } if ($services) { foreach ($svc in $services) { Write-Host "[!] Vulnerable Service Found: $($svc.Name)" -ForegroundColor Red Write-Host " Path: $($svc.PathName)" # Logic to determine potential hijack points $path = $svc.PathName $splitPath = $path -split ' ' $hijackPath = "" for ($i = 0; $i -lt $splitPath.Count - 1; $i++) { $hijackPath += $splitPath[$i] Write-Host " Potential Hijack Point: $hijackPath.exe" $hijackPath += " " } } } else { Write-Host "[+] No obviously vulnerable unquoted services found with spaces." } } # Execute the check Get-UnquotedServicePaths # Note: Exploitation requires placing a malicious executable (e.g., 'Program.exe') # in one of the identified hijack points (e.g., C:\) and waiting for the service to restart # or forcing a restart (if permissions allow).
