Mozart FM Transmitter, published on 26 Nov 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-66263 in the wild and no public exploit code.\n\nAffected product: DB Electronica Telecomunicazioni S.p.A. Mozart FM Transmitter. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-66263/ (Markdown: https://insights.sbomify.com/CVE-2025-66263/index.md)","id":"CVE-2025-66263","markdown":"https://insights.sbomify.com/CVE-2025-66263/index.md","name":"CVE-2025-66263","record":{"aliases":["GHSA-935j-38v5-5gwh"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"FM Transmitter","requires_auth":"none","summary":"Unauthenticated attackers can read arbitrary files on DB Electronica Mozart FM Transmitters via null byte injection in the download endpoint.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gridware","cpe":[{"product":"mozart_dds_next_1000_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_100_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_2000_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_3000_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_300_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_30_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_3500_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_500_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_50_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_6000_firmware","vendor":"dbbroadcast"},{"product":"mozart_dds_next_7000_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_1000_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_100_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_2000_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_3000_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_300_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_30_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_3500_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_500_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_50_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_6000_firmware","vendor":"dbbroadcast"},{"product":"mozart_next_7000_firmware","vendor":"dbbroadcast"}],"cvss":{"score":8.9,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-158","name":"Improper Neutralization of Null Byte or NUL Character"}],"description":"Unauthenticated Arbitrary File Read via Null Byte Injection in DB Electronica Telecomunicazioni S.p.A.

Running on PHP 5.3.2 (pre-5.3.4), the application is vulnerable to null byte injection (%00), allowing attackers to bypass the extension restriction and traverse paths. By requesting `filename=../../../../etc/passwd%00`, the underlying C functions treat the null byte as a string terminator, ignoring the appended `.tgz` and enabling unauthenticated arbitrary file disclosure of any file readable by the web server user.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Unauthenticated Arbitrary File Read via Null Byte Injection","id":"CVE-2025-66263","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Unquoted Service path in UPSilon2000V6.0 SYSTEM privilege service","id":"CVE-2025-66264"},"packages":[],"prev":{"headline":"Arbitrary File Overwrite via Tar Extraction Path Traversal","id":"CVE-2025-66262"},"products":["Mozart FM Transmitter"],"published":"2025-11-26","related":[{"cvss_score":9.9,"headline":"Unauthenticated OS Command Injection (start_upgrade.php)","id":"CVE-2025-66253","kev_date_added":null,"published":"2025-11-26"},{"cvss_score":9.9,"headline":"Unauthenticated Arbitrary File Upload (upgrade_contents.php)","id":"CVE-2025-66255","kev_date_added":null,"published":"2025-11-26"},{"cvss_score":9.9,"headline":"Unauthenticated Arbitrary File Upload (patch_contents.php)","id":"CVE-2025-66256","kev_date_added":null,"published":"2025-11-26"},{"cvss_score":9.9,"headline":"Unauthenticated OS Command Injection (restore_settings.php)","id":"CVE-2025-66261","kev_date_added":null,"published":"2025-11-26"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2025-63228","kev_date_added":null,"published":"2025-11-18"},{"cvss_score":9.3,"headline":"Authenticated Root Remote Code Execution through improper filtering of HTTP post request parameters","id":"CVE-2025-66259","kev_date_added":null,"published":"2025-11-26"},{"cvss_score":9.3,"headline":"Arbitrary File Overwrite via Tar Extraction Path Traversal","id":"CVE-2025-66262","kev_date_added":null,"published":"2025-11-26"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-26","vendors":["DB Electronica Telecomunicazioni S.p.A."]},"summary":"Unauthenticated attackers can read arbitrary files on DB Electronica Mozart FM Transmitters via null byte injection in the download endpoint.","url":"https://insights.sbomify.com/CVE-2025-66263/"}
