Authenticated code execution via editable sitemap hook
Published Nov 3, 2023 · Updated Sep 6, 2024
Code injection in Intelliants Subrion CMS 4.2.1 allows remote authenticated users to execute PHP code through a backend hook. The Hooks editor stores attacker-controlled sitemapGeneration hook content, and Generate Sitemap passes that content to eval(). Access to the backend Hooks and sitemap controls is required; successful exploitation can write a web shell and run code as the web server.
