  1. Description:
  
  The Anydesk installs as a service with an unquoted service path running with SYSTEM privileges.
  This could potentially allow an authorized but non-privileged local
  user to execute arbitrary code with elevated privileges on the system.
  
  2. Proof
  
  C:\>sc qc anydesk
  [SC] QueryServiceConfig SUCCESS
  
  SERVICE_NAME: anydesk
  TYPE : 10WIN32_OWN_PROCESS
  START_TYPE : 2 AUTO_START
  ERROR_CONTROL: 1 NORMAL
  BINARY_PATH_NAME : C:\Program Files\AnyDesk\AnyDesk.exe --service
  LOAD_ORDER_GROUP :
  TAG: 0
  DISPLAY_NAME : AnyDesk Service
  DEPENDENCIES : RpcSs
  SERVICE_START_NAME : LocalSystem
  
  
  3. Exploit:
  
  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 user's code would execute with the elevated privileges
  of the application.
