RFNTPS, published on 20 May 2021. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20719 in the wild and no public exploit code.\n\nAffected product: NIPPON ANTENNA Co.,Ltd. RFNTPS. 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-2021-20719/ (Markdown: https://insights.sbomify.com/CVE-2021-20719/index.md)","id":"CVE-2021-20719","markdown":"https://insights.sbomify.com/CVE-2021-20719/index.md","name":"CVE-2021-20719","record":{"aliases":["GHSA-7g2h-82xr-x8jw"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"RFNTPS firmware","requires_auth":"high_privilege","summary":"An attacker on the same network can execute arbitrary OS commands with root privileges on RFNTPS devices.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"rfntps_firmware","vendor":"nippon-antenna"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"RFNTPS firmware versions System_01000004 and earlier, and Web_01000004 and earlier allow an attacker on the same network segment to execute arbitrary OS commands with a root privilege 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":"Command injection in RFNTPS","id":"CVE-2021-20719","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"SQL injection in KonaWiki2","id":"CVE-2021-20720"},"packages":[],"prev":{"headline":"Denial of service in mod auth openidc","id":"CVE-2021-20718"},"products":["RFNTPS"],"published":"2021-05-20","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["NIPPON ANTENNA Co.,Ltd."]},"summary":"An attacker on the same network can execute arbitrary OS commands with root privileges on RFNTPS devices.","url":"https://insights.sbomify.com/CVE-2021-20719/"}
