Sflog! CMS 1.0 contains an authenticated arbitrary file upload vulnerability in the blog management interface. The application ships with default credentials (admin:secret) and allows authenticated users to upload files via manage.php. The upload mechanism fails to validate file types, enabling attackers to upload a PHP backdoor into a web-accessible directory (blogs/download/uploads/). Once uploaded, the file can be executed remotely, resulting in full remote code execution.
The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
