Summary

The Extra Checkout Options plugin for WordPress up to version 2.3.2 allows authenticated users with Subscriber-level access and above to upload PHP files. Missing authorization and nonce validation in the eco_save_settings() function enables modification of allowed file types, followed by PHP file upload via the frontend, leading to remote code execution.

Risk Assessment

An attacker can gain full control of the WordPress server by executing arbitrary PHP code, risking data theft, defacement, or site takeover.

Recommendation

Update the plugin to the latest version (above 2.3.2) and restrict Subscriber user permissions to the minimum.

Original NVD description (English source)

The Extra Checkout Options (addon for Extra Product Options & Add-Ons for WooCommerce) plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.3.2. This is due to missing authorization and nonce validation in the eco_save_settings() function, which allows low-privileged authenticated users to modify the tc_eco_custom_file_types upload allowlist setting, combined with insufficient authorization on the wc_eco_upload_file AJAX action. This makes it possible for authenticated attackers, with Subscriber-level access and above, to allow PHP uploads, upload a PHP file using the frontend upload nonce exposed on cart and checkout pages, and achieve remote code execution. NOTE: This vulnerability was partially fixed in version 2.3.2.
