CVE-2024-9234 is a critical vulnerability in the GutenKit – Page Builder Blocks, Patterns, and Templates for Gutenberg Block Editor plugin for WordPress. In all versions up to and including 2.1.0, the install_and_activate_plugin_from_external() function exposed through the install-active-plugin REST API endpoint lacks a required capability check. Because authorization is not properly enforced, an unauthenticated attacker can invoke functionality intended for privileged plugin installation and activation workflows. This allows arbitrary plugin installation and activation, and can also be abused to upload attacker-controlled files disguised as plugins. In a typical WordPress deployment, successful abuse can lead to execution of attacker-supplied PHP code on the server through installation of a malicious plugin payload.

This repository contains a Python proof-of-concept exploit for CVE-2024-9234, targeting the WordPress GutenKit plugin (version 2.1.0 and below). The exploit consists of a single script (CVE-2024-9234.py) and a README file. The script first checks if the target WordPress site is running the vulnerable GutenKit plugin by requesting the plugin's readme.txt file and verifying the version. If the site is vulnerable, it then exploits an unauthenticated endpoint ('/wp-json/gutenkit/v1/install-active-plugin') to upload and install a plugin (in this case, 'popularis-extra.1.2.6.zip' from the official WordPress repository) without authentication. This demonstrates the ability to perform arbitrary file uploads, which could be further weaponized by uploading a malicious plugin or webshell. The exploit is network-based and requires only the base URL of the target WordPress site as input.
