Tom Samplonius commented on AMQ-1272:
-------------------------------------
Just some further clarification. activemq-5.0-20070621 with the patch has the
following behavior:
1. If a Stomp client uses the wrong password and/or wrong user name, it will
just block forever when trying to send to a destination.
2. If a Stomp client uses a matching username and password, but that user does
not have permission to write to the queue (as in the above nonsensical auth
configuration, where none of the groups match), ActiveMQ will just eat the
message and log an exception for each message:
ERROR Service - Async error occurred:
java.lang.SecurityException: User system is not authorized to write to:
queue://foo
java.lang.SecurityException: User system is not authorized to write to:
queue://foo
So the client is never disconnected, and never is sent an error. It is a step
in the right direction.
> Stomp protocol does not correctly check authentication (security hole)

> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.0.0
> Environment: 4.2-SNAPSHOT
> Reporter: Tom Samplonius
> Priority: Blocker
> Fix For: 4.1.2, 5.0.0

> Attachments: stomp.diff

>
> 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.
