Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-66261, published on 2025-11-26, is an unauthenticated OS command injection vulnerability (CWE-78) in the restore_settings.php component of DB Electronica Telecomunicazioni S.p.A. Mozart FM Transmitter devices. It affects versions 30, 50, 100, 300, 500, 1000, 2000, 3000, 3500, 6000, and 7000. The vulnerable endpoint at /var/tdf/restore_settings.php takes the user-controlled $_GET["name"] parameter, applies urldecode() to it, and passes the result directly into the exec() PHP function without validation or escaping, enabling command injection.
An unauthenticated attacker (PR:N) with network access (AV:N) can exploit this low-complexity (AC:L) vulnerability by crafting a malicious URL-decoded "name" parameter containing shell metacharacters such as ;, |, or &&. This allows arbitrary command execution as the web server user, with high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), resulting in a CVSS v3.1 base score of 9.8.

Vulnerability Data
Unauthenticated OS Command Injection (restore_settings.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 URL-decoded name parameter passed to exec() allows remote code execution.…
more
The `/var/tdf/restore_settings.php` endpoint passes user-controlled `$_GET["name"]` parameter through `urldecode()` directly into `exec()` without validation or escaping. Attackers can inject arbitrary shell commands using metacharacters (`;`, `|`, `&&`, etc.) to achieve unauthenticated remote code execution as the web server user.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
