Internet Explorer has received a lot of attention lately for the way
it handles requests for external URIs.... Nate and I have warned that
IE isn't the only browser with URI handling issues....
I've posted a PoC for remote command execution in Firefox (2.0.0.5),
Netscape Navigator 9, and mozilla at:
http://xs-sniper.com/blog/2007/07/24/remote-command-execution-in-firefox-2005/
These specific examples are built for WinXP SP2 WITH NO OTHER EXTERNAL
EMAIL programs installed. Users with Outlook, notes, or other
external mail programs installed may have had their URI handlers
modified by the external program.
Take some improperly registered URIs combined with a lack of
sanitation by the browser and we've got problems.... its time to take
another look at the URIs on your machine...
