Windows handles service paths in a very specific manner when they are not explicitly wrapped in quotation marks. If a service path contains spaces and lacks quotation marks, the Windows Service Control Manager (SCM) will interpret the path as a sequence of execution attempts, stopping at each space to look for an executable file. How Windows Interprets Unquoted Paths

Alternatively, you can use a command-line tool to identify and fix unquoted paths across your system. CVE-2021-47790 Detail - NVD

, was recently highlighted for its potential to grant attackers administrative control. Understanding the Risk: CVE-2021-47790

When Windows tries to start the service, it reads the path one segment at a time. For example, if the path is C:\Program Files\Active WebCam\WebCam.exe , Windows might mistakenly try to run a malicious file named C:\Program.exe or C:\Program Files\Active.exe instead. How it was Patched

You can check for this vulnerability on your Windows machine using Command Prompt: Open Command Prompt as Administrator.

: If you're tech-savvy, you can check the ImagePath for the service in the Windows Registry Editor. It should look like "C:\Program Files\...\webcam.exe" (with quotes).

wmic service get name,displayname,pathname,startmode | findstr /i "Active Webcam" Use code with caution. The output revealed a path structurally similar to: C:\Program Files\Active Webcam\WebcamService.exe Use code with caution.
