Basic Usage
There are two ways to execute this post module.
From the Meterpreter prompt
The first is by using the "run" command at the Meterpreter prompt. It allows you to run the post module against that specific session:
meterpreter > run post/linux/busybox/jailbreak
From the msf prompt
The second is by using the "use" command at the msf prompt. You will have to figure out which session ID to set manually. To list all session IDs, you can use the "sessions" command.
msf > use post/linux/busybox/jailbreak
msf post(jailbreak) > show options
... show and set options ...
msf post(jailbreak) > set SESSION session-id
msf post(jailbreak) > exploit
If you wish to run the post against all sessions from framework, here is how:
1 - Create the following resource script:
framework.sessions.each_pair do |sid, session|
run_single("use post/linux/busybox/jailbreak")
run_single("set SESSION #{sid}")
run_single("run")
end
2 - At the msf prompt, execute the above resource script:
msf > resource path-to-resource-script
Required Options
