CVE-2023-46845Network attack vector

Administrator code execution via unsandboxed Twig templates

Published Nov 7, 2023 · Updated Sep 4, 2024

Code injection in EC-CUBE 3 and 4 allows remote authenticated users with administrative privileges to execute arbitrary server code. The product-detail free-area renderer, and the page-metatag renderer in version 4, pass stored administrator-controlled strings to template_from_string without sandboxing. Administrative access is required; successful exploitation runs code with the web application's server-side privileges, exposing its data and host operations.
