It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2018-16198 and fix it if it is affected.\n\nWhat it is: CVE-2018-16198 is a high-severity missing authorization vulnerability in Toshiba Home gateway HEM-GW16A and Toshiba Home gateway HEM-GW26A, published on 9 Jan 2019. 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-2018-16198 in the wild and no public exploit code.\n\nAffected product: Toshiba Home gateway HEM-GW16A and Toshiba Home gateway HEM-GW26A. 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-2018-16198/ (Markdown: https://insights.sbomify.com/CVE-2018-16198/index.md)","id":"CVE-2018-16198","markdown":"https://insights.sbomify.com/CVE-2018-16198/index.md","name":"CVE-2018-16198","record":{"aliases":["GHSA-qjvx-g87m-78xp"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["privilege_escalation","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Home gateway","requires_auth":"none","summary":"An attacker on the same network can access an undocumented developer screen to perform unauthorized operations on the device.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"hem-gw16a_firmware","vendor":"toshiba"},{"product":"hem-gw26a_firmware","vendor":"toshiba"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[],"description":"Toshiba Home gateway HEM-GW16A 1.2.9 and earlier, Toshiba Home gateway HEM-GW26A 1.2.9 and earlier may allow an attacker on the same network segment to access a non-documented developer screen to perform operations on the affected device.","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":"Missing authorization in Toshiba Home gateway HEM-GW16A and Toshiba Home gateway HEM-GW26A","id":"CVE-2018-16198","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in Toshiba Home gateway HEM-GW16A and Toshiba Home gateway HEM-GW26A","id":"CVE-2018-16199"},"packages":[],"prev":{"headline":"Auth bypass in Toshiba Home gateway HEM-GW16A and Toshiba Home gateway HEM-GW26A","id":"CVE-2018-16197"},"products":["Toshiba Home gateway HEM-GW16A and Toshiba Home gateway HEM-GW26A"],"published":"2019-01-09","related":[{"cvss_score":9.8,"headline":"Missing authorization in Toshiba Home gateway HEM-GW16A","id":"CVE-2017-2234","kev_date_added":null,"published":"2017-07-07"},{"cvss_score":9.8,"headline":"Auth bypass in Toshiba Home gateway HEM-GW16A","id":"CVE-2017-2235","kev_date_added":null,"published":"2017-07-07"},{"cvss_score":9.8,"headline":"Hardcoded credentials in Toshiba Home gateway HEM-GW16A","id":"CVE-2017-2236","kev_date_added":null,"published":"2017-07-07"},{"cvss_score":9.8,"headline":"Command injection in Toshiba Home gateway HEM-GW16A","id":"CVE-2017-2237","kev_date_added":null,"published":"2017-07-07"},{"cvss_score":8.8,"headline":"Command injection in Toshiba Home gateway HEM-GW16A and Toshiba Home gateway HEM-GW26A","id":"CVE-2018-16200","kev_date_added":null,"published":"2019-01-09"},{"cvss_score":8.8,"headline":"Hardcoded credentials in Toshiba Home gateway HEM-GW16A and Toshiba Home gateway HEM-GW26A","id":"CVE-2018-16201","kev_date_added":null,"published":"2019-01-09"}],"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":"2024-08-05","vendors":["Toshiba Lighting \u0026 Technology Corporation"]},"summary":"An attacker on the same network can access an undocumented developer screen to perform unauthorized operations on the device.","url":"https://insights.sbomify.com/CVE-2018-16198/"}
