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-2020-5548 in the wild and no public exploit code.\n\nAffected product: Yamaha network devices. 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-2020-5548/ (Markdown: https://insights.sbomify.com/CVE-2020-5548/index.md)","id":"CVE-2020-5548","markdown":"https://insights.sbomify.com/CVE-2020-5548/index.md","name":"CVE-2020-5548","record":{"aliases":["GHSA-4f29-4fj4-943j"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Yamaha network router","requires_auth":"none","summary":"Remote attackers can cause a denial of service on Yamaha routers and firewalls via unspecified vectors.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"fwx120_firmware","vendor":"yamaha"},{"product":"nvr500_firmware","vendor":"yamaha"},{"product":"nvr510_firmware","vendor":"yamaha"},{"product":"nvr700w_firmware","vendor":"yamaha"},{"product":"rtx1200_firmware","vendor":"yamaha"},{"product":"rtx1210_firmware","vendor":"yamaha"},{"product":"rtx3500_firmware","vendor":"yamaha"},{"product":"rtx5000_firmware","vendor":"yamaha"},{"product":"rtx810_firmware","vendor":"yamaha"},{"product":"rtx830_firmware","vendor":"yamaha"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"Yamaha LTE VoIP Router(NVR700W firmware Rev.15.00.15 and earlier), Yamaha Gigabit VoIP Router(NVR510 firmware Rev.15.01.14 and earlier), Yamaha Gigabit VPN Router(RTX810 firmware Rev.11.01.33 and earlier, RTX830 firmware Rev.15.02.09 and earlier, RTX1200 firmware Rev.10.01.76 and earlier, RTX1210 firmware Rev.14.01.33 and earlier, RTX3500 firmware Rev.14.00.26 and earlier, and RTX5000 firmware Rev.14.00.26 and earlier), Yamaha Broadband VoIP Router(NVR500 firmware Rev.11.00.38 and earlier), and Yamaha Firewall(FWX120 firmware Rev.11.03.27 and earlier) allow remote attackers to cause a denial of service via unspecified vectors.","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":"Denial of service in Yamaha network devices","id":"CVE-2020-5548","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site request forgery in EasyBlocks IPv6","id":"CVE-2020-5549"},"packages":[],"prev":{"headline":"Denial of service in Mitsubishi Electric MELQIC IU1 series","id":"CVE-2020-5547"},"products":["Yamaha network devices"],"published":"2020-04-01","related":[],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Yamaha Corporation"]},"summary":"Remote attackers can cause a denial of service on Yamaha routers and firewalls via unspecified vectors.","url":"https://insights.sbomify.com/CVE-2020-5548/"}
