Hi Gunnar,
I highly recommend reading through this note if it applies to your version of JBoss:
https://access.redhat.com/solutions/30744
It's an older vulnerability with a poorly secured JMX console. Although you should be ok if you're running on an internal network and/or non-standard port, you should exercise extreme caution if you're running a publically accessible SAS server without a reverse proxy. I've had to chase a couple of trojans down, it's not fun. The fix in that link is relatively straightforward.
Hope this helps.
Nik
