Description

This module exploits a flaw in the WSReset.exe file associated with the Windows Store. This binary has autoelevate privs, and it will run a binary file contained in a low-privilege registry location. By placing a link to the binary in the registry location, WSReset.exe will launch the binary as a privileged user.

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