Schneier on Security: Man-in-the-Middle Attack Against SSL 3.0/TLS 1.0

While Rizzo and Duong believe BEAST is the first attack against SSL 3.0 that decrypts HTTPS requests, the vulnerability that BEAST exploits is well-known; BT chief security technology officer Bruce Schneier and UC Berkeley’s David Wagner pointed out in a 1999 analysis of SSL 3.0 that “SSL will provide a lot of known plain-text to the eavesdropper, but there seems to be no better alternative.” And TLS’s vulnerability to man-in-the middle attacks was made public in 2009. The IETF’s TLS Working Group published a fix for the problem, but the fix is unsupported by SSL.

The comments following the article have quite a bit of interesting information, at Schneier on Security: Man-in-the-Middle Attack Against SSL 3.0/TLS 1.0.
