ThemeREX Addons (Various Versions) - Missing Authorization

Missing Authorization
CVE CVE-2020-10257
CVSS Critical (9.8)
Publicly Published March 9, 2020
Last Updated September 4, 2024
Researcher Chloe Chamberland
Description

The ThemeREX Addons plugin for WordPress is vulnerable to Improper Access Control in various versions. This is due to the /trx_addons/v2/get/sc_layout REST API endpoint, allowing for PHP functions to be executed by any users, because includes/plugin.rest-api.php calls trx_addons_rest_get_sc_layout with an unsafe sc parameter. This makes it possible for unauthenticated attackers to execute functions like wp_insert_user, allowing attackers the ability to inject administrative user accounts and take over sites. See https://www.wordfence.com/blog/2020/03/zero-day-vulnerability-in-themerex-addons-now-patched/ for accurate version information.
