Demo – IE 5.5/Outlook java security vulnerability – reading arbitrary local files and URLs

An attacker may gain read access on remote systems by specifying a custom codebase in a Java applet, and delivering to the victim(s) via HTML email or a website. Any arbitrary codebase can be referenced by a java applet that was loaded by an <OBJECT> tag in conjunction with a jar file when using Microsoft Internet Explorer or Outlook/Outlook Express. This allows for the possibility of any known file to be read by a remote attacker.

Mitigation:

Disable Java applets in the browser or use a browser that does not support Java applets.
