Prior to version 20.17.0, the product custom option file upload in OpenMage LTS uses an incomplete blocklist (`forbidden_extensions = php,exe`) to prevent dangerous file uploads. This blocklist can be trivially bypassed by using alternative PHP-executable extensions such as `.phtml`, `.phar`, `.php3`, `.php4`, `.php5`, `.php7`, and `.pht`. Files are stored in the publicly accessible `media/custom_options/quote/` directory, which lacks server-side execution restrictions for some configurations, enabling Remote Code Execution if this directory is not explicitly denied script execution. Version 20.17.0 patches the issue."}, {"lang": "es", "value": "Magento Long Term Support (LTS) es un proyecto no oficial, impulsado por la comunidad, que proporciona una alternativa a la plataforma de comercio electr\u00f3nico Magento Community Edition con un alto nivel de compatibilidad con versiones anteriores.
