  # Exploit Title: AnyDesk 2.5.0 Unquoted Service Path Elevation of Privilege # Date: 22/09/2016 # Exploit Author: Tulpa # Contact: tulpa@tulpa-security.com # Author website: www.tulpa-security.com # Vendor Homepage: http://anydesk.com # Software Link: http://anydesk.com/download # Version: Software Version 2.5.0 # Tested on: Windows 10 Professional x64, Windows XP SP3 x86, Windows Server 2008 R2 x64 # Shout-out to carbonated and ozzie_offsec   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.
