The Plantronics Hub client application for Windows makes use of an automatic update service `SpokesUpdateService.exe` which automatically executes a file specified in the `MajorUpgrade.config` configuration file as SYSTEM. The configuration file is writable by all users by default. This module has been tested successfully on Plantronics Hub version 3.13.2 on Windows 7 SP1 (x64).

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/plantronics_hub_spokesupdateservice_privesc
msf exploit(plantronics_hub_spokesupdateservice_privesc) > show targets
...targets...
msf exploit(plantronics_hub_spokesupdateservice_privesc) > set TARGET < target-id >
msf exploit(plantronics_hub_spokesupdateservice_privesc) > show options
...show and set options...
msf exploit(plantronics_hub_spokesupdateservice_privesc) > 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.
