User Summary

Attempts to run a command via WebExService, using the WebExec vulnerability. Given a Windows account (local or domain), this will start an arbitrary executable with SYSTEM privileges over the SMB protocol.

The argument webexec_command will run the command directly. It may or may not start with a GUI. webexec_gui_command will always start with a GUI, and is useful for running commands such as "cmd.exe" as SYSTEM if you have access.
