This Metasploit module uses the Regsvr32.exe Application Whitelisting Bypass technique as a way to run a command on a target system. The major advantage of this technique is that you can execute a static command on the target system and dynamically and remotely change the command that will actually run (by changing the value of CMD). This is useful when combined with persistence methods (e.g., a recurring scheduled task) or when flexibility is needed through the use of a single command (e.g., as Rubber Ducky payload).

In this case, the authors 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, they use gpedit.msc as the auto-elevated CLR process, but others would work, too.
dca3da70d2a2d1b66b1779e541ee7478df88bc4ec265fa33d2fffcb756920230This Metasploit module simplifies the Regsvr32.exe Application Whitelisting Bypass technique. The module creates a web server that hosts an .sct file. When the user types the provided regsvr32 command on a system, regsvr32 will request the .sct file and then execute the included PowerShell command. This command then downloads and executes the specified payload (similar to the web_delivery module with PSH). Both web requests (i.e., the .sct file and PowerShell download and execute) can occur on the same port.

Currently only the InstallUtil method is provided, but future methods can be added easily.
