The issue is triggered when users "Edit" specially crafted documents containing a 'meta' HTML tag set to 'ProgId' and its content set to a 'ProgId' of choice eg. 'HTAFILE', usually through MS IE browser or a MS Office component (The Edit HTML app 'msohtmed.exe'). Some Office versions will add an "Edit" menu option to html and xhtml files, making it possible to exploit the vulnerability locally or remotely (usually through network shares) This is the 'ProgId' exploit: Similar to the old Windows Shell / Internet Explorer ClassId vulnerabilit(ies) that haunted Windows 98/2000/XP in the past.'. On patched systems, the PoC file will always open in Notepad.
