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."},"fix_prompt":"Check this codebase for CVE-2025-66255 and fix it if it is affected.\n\nWhat it is: CVE-2025-66255 is a critical vulnerability in DB Electronica Telecomunicazioni S.p.A. 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: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-66255 exists.\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-2025-66255/ (Markdown: https://insights.sbomify.com/CVE-2025-66255/index.md)","id":"CVE-2025-66255","markdown":"https://insights.sbomify.com/CVE-2025-66255/index.md","name":"CVE-2025-66255","record":{"aliases":["GHSA-22cp-hq23-fv85"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"FM Transmitter","requires_auth":"none","summary":"Unauthenticated attackers can upload malicious firmware to FM transmitters via an unvalidated endpoint, leading to remote code execution.","user_interaction":"not_required","vuln_class":"file_upload"},"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":9.9,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"},{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"Unauthenticated Arbitrary File Upload (upgrade_contents.php) in DB Electronica Telecomunicazioni S.p.A.
