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 : 10 WIN32_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.
