CVE-2025-66255

CVSS 9.9v4.0pub. 2025-11-26upd. 2025-12-03

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

🤖 AI Analysis
How it works

The upgrade_contents.php endpoint responsible for firmware updates does not verify file headers, cryptographic signatures, or enforce .tgz format. Lack of authentication (CWE-345) combined with lack of verification of uploaded files (CWE-434) allows uploading any file, including a malicious firmware package. After uploading such a package, an attacker can gain the ability to execute code remotely on the device.

Impact

An attacker without any privileges can upload malicious firmware or any file, leading to complete takeover of the device and potential breach of confidentiality and integrity of data in the network to which the device is connected.

Mitigation & patch

Apply patches available from the manufacturer according to the references. Until the fix is implemented, it is recommended to isolate devices from public networks, restrict access to the management interface to trusted IP addresses only, and monitor traffic directed to the upgrade_contents.php endpoint.

Who is affected

DB Electronica Telecomunicazioni S.p.A. Mozart FM Transmitter in versions: 30, 50, 100, 300, 500, 1000, 2000, 3000, 3500, 6000, 7000
