Novatel's MiFi, little things that do the 3G talkin' for you, but from what we're seeing here current users may be about to experience something altogether different: fear. A hack that is both very nasty and easy to execute has been shown which would, most troublingly, allow a malicious page to modify the MiFi settings on behalf of the user, possibly disabling security or even locking out the owner of the router, as shown in a quick demonstration video after the break. A factory reset fixes it all, of course, but doesn't do anything to alleviate the apparently shoddy security mechanisms at play here. Time for another firmware update, perhaps?
1/19/2010 Update: We've received a note from a Novatel representative indicating that the CGI parameters the device uses for configuration were designed to be "intentionally programmable" to ease remote setup. The statement also clarifies that a user's data will not be exposed via this hack, and that the company is working on a patch. The full statement after the break if you're inclined to read it.
