Description

This module exploits the RPC service impersonation vulnerability detailed in
Microsoft Bulletin MS10-061. By making a specific DCE RPC request to the
StartDocPrinter procedure, an attacker can impersonate the Printer Spooler service
to create a file. The working directory at the time is %SystemRoot%\system32.
An attacker can specify any file name, including directory traversal or full paths.
By sending WritePrinter requests, an attacker can fully control the content of
the created file.

In order to gain code execution, this module writes to a directory used by Windows
Management Instrumentation (WMI) to deploy applications. This directory (Wbem\Mof)
is periodically scanned and any new .mof files are processed automatically. This is
the same technique employed by the Stuxnet code found in the wild.
