JRE Java TLS Renegotiation Vulnerability

Severity CVSS Published Added Modified
6 (AV:N/AC:M/Au:N/C:N/I:P/A:P) November 09, 2009 April 02, 2010 December 04, 2013

Description

The TLS protocol as well as the SSL protocol 3.0 and possibly earlier do not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue. This affects Java 6 update 18, Java 5.0 update 23 and Java 1.4.2_25.
