MFSA2007-27 patched the demonstrations but not the underlying Windows Shell file-type handling. Rios and McFeters show a common handler can still be driven with a single unexpected URI passed through mailto, nntp, news or snews with no user interaction: Firefox hands the URI to the Windows File Handler, which launches Windows Scripting Host on an attacker-named file.
