Tom Samplonius commented on AMQ-1272:
-------------------------------------
Well, the Perl Net::Stomp client definitely notices if the socket goes away,
because if I kill ActiveMQ, my client reports an immediate error:
Error reading command: at
/usr/local/lib/perl5/site_perl/5.8.8/Net/Stomp/Frame.pm line 37, <GEN0> line
25076.
This is expected though. When the receive_frame() method is called, Net::Stomp
does a blocking read on a socket. If that socket is closed, the read will
return with an error code. And then the Net::Stomp kicks out an "Error reading
command" exception.
I have also retested this with a 5.0 snapshot from July 12, with the stomp.diff
patch that I posed above. The behavior is the same. A Stomp client will just
block during login. I can see in netstat that there is a one 61613 socket open
as well, so it is not definitely not being closed by ActiveMQ.

> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.0.0

> ActiveMQ does not correctly validate the username and password of Stomp
> clients. A security exception is generated, but ignored, leaving the client
> connected, and with full and unrestricted access to ActiveMQ.
> Further description, and a partial patch:
> http://www.nabble.com/Getting-Stomp-support-to-a-usable-state...-tf3858629s2354.html#a11060452

> BTW, while the patch in the above post, is crude, however, leaving
> unauthenticated users connected with full-access makes ActiveMQ and Stomp
> pretty unusable. So please apply the path, rather than do nothing.
