CVE-2015-2673 is a privilege escalation and remote code execution vulnerability in the WP EasyCart plugin for WordPress, affecting versions 1.1.30 through 3.0.20. The vulnerability resides in the ec_ajax_update_option and ec_ajax_clear_all_taxrates functions in inc/admin/admin_ajax_functions.php, which fail to properly validate user input for the option_name and option_value parameters. This allows authenticated non-admin users to update arbitrary WordPress options, including those that control administrative privileges and site configuration, potentially leading to full site compromise.

This repository contains a single Metasploit auxiliary module targeting a privilege escalation vulnerability (CVE-2015-2673) in the WordPress WP EasyCart plugin (versions 1.1.30 to 3.0.20). The exploit requires valid WordPress credentials and abuses insufficient validation in the plugin's AJAX functions to change critical site options: it sets the admin email to an attacker-controlled address, enables user registration, and sets the default role to administrator. The attacker can then register a new account via the public registration page, gaining admin privileges. The module interacts with the vulnerable endpoint at /wp-admin/admin-ajax.php and references the plugin's vulnerable code in /inc/admin/admin_ajax_functions.php. The code is written in Ruby and is structured as a standard Metasploit module.
