The java_jmx_scanner module uses the Msf::Exploit::Remote::Java::Rmi::Client library to perform a handshake with a Java JMX MBean server. JMX MBean listens in 1099 by default, and is used to manage and monitor Java applications.

The module returns whether the target is a Java JMX MBeans server and also outputs if the server requires authentication.

Vulnerable Application

While many implementations of JMX are available, the module was successfully tested against an Apache ActiveMQ 5.13.3 server with JMX enabled. For convenience, a docker container (antonw/activemq-jmx) supports JMX and can be tweaked to require authentication.

Verification Steps

See PR#10401 for general information, and this specific comment for steps to require JMX authentication in the container. In summary:

docker run -p 1099:1099 antonw/activemq-jmx 
docker exec -u=root -it `docker ps -q` /bin/bash

# echo -e "monitorRole QED\ncontrolRole R&D" /etc/java-7-openjdk/management/jmxremote.password
# chown activemq /etc/java-7-openjdk/management/jmxremote.password
# chmod 400 /etc/java-7-openjdk/management/jmxremote.password
# sed 's/-Dcom.sun.management.jmxremote.authenticate=false/-Dcom.sun.management.jmxremote.authenticate=true/' /opt/apache-activemq-5.13.3/bin/env

docker restart `docker ps -q`

Scenarios

ActiveMQ 5.13.3

Against the above-described Docker container, the workflow looks like:

msf5 auxiliary(scanner/misc/java_jmx_server) > set RHOST 127.0.0.1
msf5 auxiliary(scanner/misc/java_jmx_server) > set RPORT 1099
msf5 auxiliary(scanner/misc/java_jmx_server) > run
[*] Reloading module...

[*] 127.0.0.1:1099        - Sending RMI header...
[*] 127.0.0.1:1099        - localhost:1099 Java JMX MBean authentication required
[*] 127.0.0.1:1099        - Scanned 1 of 1 hosts (100% complete)
[*] Auxiliary module execution completed

In addition, note that services within the data model has been updated:
