So right. The standard RMI registry is going to be on 1099. And it sort of makes sense there. The interesting aspect, and one very useful, is that the JMX interfaces use an arbitrary user assigned port for its listener. Turns out this listener is just a special RMI Registry so connecting to it and dumping it using the rmi-dumpregistry script turns out to be very useful. JMX can expose the internal state of a service and allow for remote changes to that service. Finding instances of this misconfigured listening to anything and willing to talk unauthenticated or lamely authenticated is a valuable thing for someone doing a security audit of a site. I understand that the nmap team is looking at ways to scale scans massively... I also get with service fingerprinting that sending lots of strange junk at certain ports has unwanted results (see printers), but I also think that the expectation of a user using service fingerprinting is that nmap is trying everything reasonable against a service. Maybe this is an opportunity to add a flag to ignore ports and try all service fingerprints against a listener that didn't fingerprint in the original pass? I'm trying to think of ways to balance the expectation an auditor focusing on one site has vs the need to be able to scan an entire organization in a reasonable timeframe... BTW, Martin great script! Thanks for putting it together!
