Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Authenticated Root Remote Code Execution via improrer user input filtering 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 in main_ok.php user supplied data/hour/time is passed directly into date shell command

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Authenticated command injection vulnerability in main_ok.php of Mozart FM Transmitter allows attackers to inject arbitrary commands via user-supplied hour/time parameters that are passed directly to a shell 'date' command without sanitization, resulting in root-level remote code execution.

MitigationImplement strict input validation and sanitization for all user-supplied parameters before shell command execution; replace direct shell command calls with safe API alternatives or parameterized methods.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify your Mozart FM Transmitter model
    Check the device label, web interface header, or system information page for the exact model name (Mozart Next 100, 1000, 2000, 30, 300, 3000, 3500, or 50)
    Affected if The model is any of the Dbbroadcast Mozart Next series (100, 1000, 2000, 30, 300, 3000, 3500, 50)
  2. Verify the web management interface is accessible
    Attempt to access the device web interface by entering the device IP address in a browser. Look for the login page or any mozart/dbbroadcast branded interface
    Affected if The web interface is reachable over HTTP/HTTPS on the network
  3. Check for the vulnerable main_ok.php script
    If the web interface is accessible, try navigating to main_ok.php (for example: http://[device-ip]/main_ok.php or check the application's PHP file list)
    Affected if The main_ok.php script exists on the web server and is accessible
  4. Confirm authentication is required
    Observe whether the web interface requires login credentials before allowing access to time/clock settings or the main_ok.php endpoint
    Affected if The interface allows authenticated users to access time parameter settings
  5. Assess network exposure of the management interface
    Review firewall rules, port scans, or network configurations to determine if the web management port (typically 80 or 443) is exposed to untrusted networks
    Affected if The web interface is accessible from outside the trusted network

You are affected if you operate any Dbbroadcast Mozart Next series FM transmitter (100, 1000, 2000, 30, 300, 3000, 3500, or 50) with its web management interface accessible on the network, since all firmware versions contain the vulnerable main_ok.php script.
