RabbitMQ 3.6.1/Erlang 18.3 TLS unzureichende Sicherheitsfehler

Ich führe RabbitMQ 3.6.1/Erlang 18.3 aus und stelle fest, dass ich keine TLSv1- oder TLSv1.1-Sitzung mit dem Broker unter Verwendung des Spring AMQP 1.5.4 einrichten kann .RELEASE Java-Client. Ich bin jedoch in der Lage, eine TLSv1.2-Sitzung mit dem Broker einzurichten. Mein RabbitMQ-Broker ist so konfiguriert, dass er alle drei von tlsv1, tlsv1.1 und tlsv1.2 unterstützt. Ich bin mit Java 1.8.0_77-b03 auf OS X.RabbitMQ 3.6.1/Erlang 18.3 TLS unzureichende Sicherheitsfehler

Hier ist meine RabbitMQ Konfiguration:

https://gist.github.com/ae6rt/de06d1efecf62fbe8cef31774d9be3d7

Erlang auf den Broker Berichte ssl Versionen

# erl

Mein RabbitMQ Broker ist so konfiguriert, TLSv1, tlsv1.1 und tlsv1.2 zu verhandeln. Warum schlägt das TLS-Setup für tlsv1 und tlsv1.1 fehl, wenn der Broker dies unterstützen sollte? Derselbe Java-Client kann TLSv1 mit einem RabbitMQ 3.3.1/Erlang R16B02-Broker aushandeln.

Vielen Dank.

Ich weiß nicht die Antwort auf Ihre Frage, aber kann ich vorschlagen, dass Sie versuchen zu debuggen, was 'ssl_handshake: select_session' in https://github.com/otphub/ssl/blob/master/src/tls_handshake zurückgibt .erl # L158? Sie können einfach eine Protokollierung hinzufügen, das Modul neu kompilieren und neu laden oder http://erlang.org/doc/man/dbg.html verwenden, um zu protokollieren, was jede Funktion empfängt und zurückgibt. – Amiramix

Vielen Dank für Ihr Feedback. Ich habe nicht explizit versucht, was Sie vorgeschlagen haben, aber Ihr Zeiger auf den Code Erlang client-hallo, in dem um Cipher-Suites herum nicht genügend Privilegien erwähnt wurden, veranlasste mich, mich auf die Chiffren zu konzentrieren. Wenn ich meine rabbitmq.config so einstellen https://gist.github.com/ae6rt/2fdcc46119821cf490c8f3c444bd11d4 kann ich alle TLS Versionen-Verbindungen erfolgreich herstellen. Ich kann nicht autoritativ meine eigene Frage nach dem Warum beantworten, aber ich vermute, dass es Erlang 18.3 nicht gut genug ist, dass erlang einige Cipher Suites als Standard verwendet. – ae6rt

Toll, dass Sie das geschafft haben. Es scheint einige Änderungen in Erlang 18 um verfügbare Chiffren zu geben: http://erlang.org/pipermail/erlang-questions/2015-September/085913.html Es gibt auch andere Updates zu Erlang 'crypto' und' ssl' Anwendungen http: //erlang.org/download/otp_src_18.3.readme könnte also sein, dass sich einige Standardeinstellungen geändert haben. – Amiramix

Es gab einige Regressionen in der Erlang ssl Anwendung in der 18.3.x-Serie. Einer von ihnen verursacht, was Sie sehen: Clients während Handshake abgelehnt, mit insufficient security auf der Serverseite angemeldet. Wenn ich mich richtig erinnere, erschien dies in Patch 18.3.3 und wurde in 18.3.4 behoben. Dies ist kein Problem für den Client.

Es gibt eine Regression in 18.3.2, behoben in 18.3.3, die den Start von RabbitMQ überhaupt verhinderte (aufgrund einer Änderung in der Repräsentation von Cipher Suites).

Daher wird empfohlen, auf 18.3 (die ursprüngliche Version) zu bleiben oder auf 19.x zu aktualisieren.

DANKE! 18.3.2 scheint in der aktuellen Version (April '17) von Ubuntu 16.04 LTS Standard zu sein.Das hat mir eine Menge Ärger erspart, als ich die Server-Version aktualisiert habe und RabbitMQ-Verbindungen kaputt gegangen sind! –
