This module exploits a vulnerability in the OpenNMS Java object which allows an unauthenticated attacker to run arbitrary code against the system.
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use exploit/linux/misc/opennms_java_serialize
msf exploit(opennms_java_serialize) > show targets
...targets...
msf exploit(opennms_java_serialize) > set TARGET < target-id >
msf exploit(opennms_java_serialize) > show options
...show and set options...
msf exploit(opennms_java_serialize) > exploit
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
