Go Pro Fusion Studio 1.2 Privilege Escalation  
  
  
Vendor: GoPro, Inc.  
Product web page: https://www.gopro.com  
Software: https://shop.gopro.com/softwareandapp/gopro-fusion-studio-app/fusion-studio.html  
Affected version: 1.2.1.400  
  
Summary: Go Pro Fusion Studio is a feature rich editing software that  
allows you to transform your content into pro-quality videos.  
  
Desc: The application suffers from an unquoted search path issue impacting  
the service 'GoProFusionDeviceDetectionService' for Windows deployed as part  
of GoPro Fusion Studio App solution. This could potentially allow an authorized  
but non-privileged local user to execute arbitrary code with elevated privileges  
on the system. A successful attempt would require the local user to be able to  
insert their code in the system root path undetected by the OS or other security  
applications where it could potentially be executed during application startup  
or reboot. If successful, the local useras code would execute with the elevated  
privileges of the application.  
  
Tested on: Microsoft Windows 10 Professional
