CVE-2025-66255

Unauthenticated Arbitrary File Upload (upgrade_contents.php) in DB Electronica Telecomunicazioni S.p.A. Mozart FM Transmitter versions 30, 50, 100, 300, 500, 1000, 2000, 3000, 3500, 6000, 7000 allows an attacker to perform Missing signature validation allows uploading malicious firmware packages.  The firmware upgrade endpoint in `upgrade_contents.php` accepts arbitrary file uploads without validating file headers, cryptographic signatures, or enforcing .tgz format requirements, allowing malicious firmware injection. This endpoint also subsequently provides ways for arbitrary file uploads and subsequent remote code execution

Summary
  • (es) La Carga de Archivos Arbitraria No Autenticada (upgrade_contents.php) en las versiones 30, 50, 100, 300, 500, 1000, 2000, 3000, 3500, 6000, 7000 del Transmisor FM Mozart de DB Electronica Telecomunicazioni S.p.A. permite a un atacante realizar la carga de paquetes de firmware maliciosos, lo cual es posible por la falta de validación de firma. El endpoint de actualización de firmware en 'upgrade_contents.php' acepta cargas de archivos arbitrarias sin validar encabezados de archivo, firmas criptográficas o aplicar requisitos de formato .tgz, lo que permite la inyección de firmware malicioso. Este endpoint también proporciona posteriormente formas para cargas de archivos arbitrarias y la posterior ejecución remota de código.
