ESA-2014-158: RSA BSAFE® Micro Edition Suite, SSL-J and SSL-C 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


RSA BSAFE SSL-C all versions

 

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). For SSL-C, a work around is provided 
to prevent this attack.

 

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. This vulnerability 
can be avoided in SSL-C 2.8.x by disabling TLS renegotiation.
 

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.

 


For customers using SSL-C 2.8.x, RSA recommends disabling TLS renegotiation. 
Instructions on how to disable TLS renegotiation can be obtained from the 
product documentation or by contacting RSA Customer Support.

 

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.
