Description
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

Executive Summary

This vulnerability is an unauthenticated arbitrary file upload issue in the firmware upgrade endpoint (upgrade_contents.php) of DB Electronica Telecomunicazioni S.p.A. Mozart FM Transmitter devices. The endpoint does not validate file headers, cryptographic signatures, or enforce the required .tgz format, allowing attackers to upload malicious firmware packages. This can lead to arbitrary file uploads and remote code execution on the affected devices.

Impact Analysis

An attacker can exploit this vulnerability to upload malicious firmware without authentication, potentially leading to remote code execution on the affected device. This can result in full compromise of the device, unauthorized control, data manipulation, or disruption of service.
