Description

An Unrestricted File Upload vulnerability in Redeight CMS version 1.0 allows authenticated attackers to achieve Remote Code Execution via the POST "/admin/index.php?module=pages&mode=FileAdd" endpoint. The application fails to validate file extensions and MIME types, permitting the upload of arbitrary PHP scripts to the publicly accessible "/uploads/files/" directory where they can be executed directly by the web server.
