Subject ActiveMQ.Advisory.Connection messages includes username and password
Date Tue, 28 Jul 2009 21:56:40 GMT
I've been working on setting up an ActiveMQ 5.2 broker and coding
clients for it for the last few weeks, and now I need to be notified
when somebody logs in. I was hoping I could use the topic
ActiveMQ.Advisory.Connection for that, so I set up a consumer on it and
tried logging in using another client and just printing the messages to
the console to see what I get.

I was extremely surprised to see that connection messages to the topic
ActiveMQ.Advisory.Connection includes the entire ConnectionInfo object
for the connection, which includes the username and password!

I have been following the Security page
(, which specifically states
that "full access rights should always be given to the ActiveMQ.Advisory
destinations" which obviously includes read access. Nowhere on the
Security page does it warn you that ActiveMQ will helpfully distribute
the clients usernames and passwords around to all the other clients for
you. This seems to happen for both the SimpleAuthenticationPlugin as
well as the JaasAuthenticationPlugin.

I haven't dug around in the code yet, I was hoping that somebody would
quickly come back to me on the forum and let me know that I have missed
some option somewhere on the docs that turns this off. Thoughts?
