## Vulnerable Application
The WordPress plugin Elementor versions 3.6.0 - 3.6.2, inclusive have a vulnerability
that allows any authenticated user to upload and execute any PHP file. This is achieved
by sending a request to install Elementor Pro from a user supplied zip file.
Any user with Subscriber or more permissions is able to execute this.
Tested against Elementor 3.6.1
### Plugin
Can be downloaded from https://wordpress.org/plugins/elementor/advanced/
## Verification Steps
1. Install the plugin, no configuration is required, just hit skip.
2. Start msfconsole
3. Do: `use exploits/multi/http/wp_plugin_elementor_auth_upload_rce`
4. Do: `set username [username]`
5. Do: `set password [password]`
6. Do: `set rhosts [ip]`
7. Do: `run`
8. You should get a shell.
## Options
### PASSWORD
The username for a user with subscriber or higher privileges
### PASSWORD
The username for a user with subscriber or higher privileges
## Scenarios
### Elementor 3.6.1 on Wordpress 5.7.7 on Ubuntu 20.04
