Description

Stored Cross-Site Scripting via XML Injection 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 Stored XSS via crafted filenames injected into patchlist.xml. User-controlled filenames are directly concatenated into `patchlist.xml` without encoding, allowing injection of malicious JavaScript payloads via crafted filenames (e.g., `<img src=x onerror=alert()>.bin`). The XSS executes when ajax.js processes and renders the XML file.
