ESA-2014-158: RSA BSAFE® Micro Edition Suite and SSL-J Triple Handshake Vulnerability
EMC Identifier: ESA-2014-158
CVE Identifier: CVE-2014-4630
Severity Rating: CVSS v2 Base Score: 6.8 (AV:N/AC:M/Au:N/C:P/I:P/A:P)
Affected Products: RSA BSAFE Micro Edition Suite (MES) all 4.0.x versions prior to 4.0.6 RSA BSAFE SSL-J all versions prior to 6.1.4
Unaffected Products: RSA BSAFE MES 4.0.6 and 4.1 RSA BSAFE SSL-J 6.1.4
Summary: RSA BSAFE Micro Edition Suite and SSL-J contain updates designed to prevent Triple Handshake attacks (CVE-2014-4630)
Details: There is a known potential vulnerability in the TLS protocol where it is possible for a malicious server to impersonate a client to another server using the client’s credentials and successfully perform a man-in-the-middle attack on the third handshake. See original advisory for more details: https://www.secure-resumption.com/
MES 4.1, MES 4.0.6 and SSL-J 6.1.4 are designed to include a fix which disallows a change of server certificate when renegotiating.
Recommendation: RSA recommends that customers on MES 4.0.x upgrade to MES 4.0.6 or to MES 4.1 and those on SSL-J 5.1.x and SSL-J 6.x upgrade to SSL-J 6.1.4 at the earliest opportunity.
Credits: The Triple Handshake attack was originally found by Antoine Delignat-Lavaud, Karthikeyan Bhargavan and Alfredo Pironti from the Prosecco research team at INRIA Paris-Rocquencourt.
