The SSL protocol, as used in certain configurations in Microsoft
Windows and Microsoft Internet Explorer, Mozilla Firefox, Google
Chrome, Opera, and other products, encrypts data by using CBC mode
with chained initialization vectors, which allows man-in-the-middle
attackers to obtain plaintext HTTP headers via a blockwise
chosen-boundary attack (BCBA) on an HTTPS session, in conjunction
with JavaScript code that uses
(1) the HTML5 WebSocket API,
(2) the Java URLConnection API, or
(3) the Silverlight WebClient API, aka a “BEAST” attack.
