Re: Apple Safari on MacOSX may reveal user's saved passwords



Injecting Javascript into a browser like this does *not* require that the attacker be on the local console. To run Applescript while logged inremotely using ssh, you can use the 'osascript' utility.

It works for:
  the same user using ssh as is on the console;
  the root user using ssh (or someone who can sudo) can inject
    Javascript into the console user's browser;
  a different non-root user on the console can do it too

That last one is particularly worrying, although I've not taken the time to figure out precisely what works and what doesn't. My test was to simply open a Terminal and 'su - foo' before using osascript, but it might, for instance, be exploitable by a setuid application.

At first glance, Firefox doesn't seem to be vulnerable (although I'm far from being an Applescript expert) to exactly this attack, but it does expose at least *some* functionality to Applescript.
