A proper solution would be to keep a list of files explicitly selected by the user and only allow uploads of files in this list. Then even if a script can manipulate the field, the browser won't upload files that have not been selected by the user.
Not necessarily that easy: notice that it is the user who enters the name of a target file. Unless you want to prevent the browser from accepting any files that were not chosen using a visual file selector widget - but in such a case, there's not much point in having a manual file path entry box in the first place. /mz
