So it could be remotely exploitable after all. On the other hand, most people don't tell their browsers to open up a separate application to handle ftp:// links.
I agree. It could be exploited in the aforementioned way(but: WS_FTP is not registered to handle FTP protocol by default). Now I am thinking of something else. Could we use a specially crafted FHF file to exploit the vulnerability? I haven't checked that yet.
