Windows Escalate UAC Protection Bypass (Via dot net profiler)



Microsoft Windows allows for the automatic loading of a profiling COM object during the launch of a CLR process based on certain environment variables ostensibly to monitor execution. In this case, we abuse the profiler by pointing to a payload DLL that will be launched as the profiling thread. This thread will run at the permission level of the calling process, so an auto-elevating process will launch the DLL with elevated permissions. In this case, we use gpedit.msc as the auto-elevated CLR process, but others would work, too.

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