Error description
IBM Sterling B2B Integrator V5.2.6.3_3: Secure+ does not work with these ciphers suites: TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384.
Local fix
STRRTC - 564470 GM / GM Circumvention: No workaround available
Problem summary
Users Affected: IBM Sterling B2B Integrator V5.2 Users Problem Description: Secure+ connections fail when ciphers suite TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 or TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 are configured. Connections fail with: JTXT="com.sterlingcommerce.cd.cdjava.CdSecurePException: MSGID=JSKT003E,RC=8,FDBK=1,CLMTHNAME=CdCommMgr.doHandshake, CDTXT="The Secure+ TLS handshake operation failed. Check the error text for TLS error information and follow diagnostic and reporting procedures.", JTXT="javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure" indicating no common ciphers were configured between the SSL client and server. Platforms Affected: Unix/Linux Windows iSeries
Problem conclusion
Resolution Summary: A code fix is provided. The CDSA no longer configures ciphers from a default set. Since the TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 and TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 ciphers are not members of this default cipher list, they were not enabled. The CDSA now correctly enables only ciphers from the session's configuration rather erroneously from a default list. Delivered In: 5020602_6 5020603_6
