Authenticated code execution via unvalidated PHP module
Published Sep 9, 2021 · Updated Aug 4, 2024
Remote code execution in Yakamara Media REDAXO CMS 5.12.1 allows remote authenticated users to run PHP code through a malicious module. The module output editor stores unvalidated PHP and executes it when a content slice using the module is saved. An authenticated administrator with module-management access can execute commands as the web-server account, enabling data access, modification, or service interruption.
