Run the following command to list services that have spaces in their paths but are not quoted:
This script checks for the specific vulnerability where the Active WebCam service binary path is stored in the Windows Registry without quotation marks. If a path (like C:\Program Files\Active WebCam\WebCam.exe ) is unquoted, Windows attempts to resolve it by checking for executables at C:\Program.exe and C:\Program Files\Active.exe sequentially. An attacker could place a malicious executable at one of those locations to gain SYSTEM privileges. The "patched" state simply implies the path is correctly quoted (e.g., "C:\Program Files\Active WebCam\WebCam.exe" ).
