CVE-2020-10257 affects the ThemeREX Addons plugin for WordPress before 2020-03-09. The plugin lacks proper access control on the /trx_addons/v2/get/sc_layout REST API endpoint. Specifically, includes/plugin.rest-api.php invokes trx_addons_rest_get_sc_layout with an unsafe sc parameter, allowing any user to reach functionality that can execute PHP functions. The issue is an access control failure on a REST endpoint combined with unsafe handling of user-supplied input, resulting in unauthorized server-side function execution.

This two-file repository contains a README and a Bash exploit script for CVE-2020-10257 in ThemeREX/TRX Addons versions before 2.5.1. exploit.sh accepts a target domain plus optional username and password, strips an input scheme, constructs an HTTPS request to the TRX Addons sc_layout REST route, and uses curl with silent and TLS-certificate-verification-bypass options (-sk). The request sets sc=wp_insert_user, role=administrator, user_login, and user_pass, attempting to create an administrative WordPress account. Although the repository labels the issue as RCE, the implemented capability is specifically unauthenticated privileged user creation; it contains no shell-command execution payload. The script uses hardcoded default credentials but permits operator customization and displays the server response.
