WSR-1166DHP3 and WSR-1166DHP4, published on 9 Jun 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-2021-20730 in the wild and no public exploit code.\n\nAffected product: BUFFALO INC. WSR-1166DHP3 and WSR-1166DHP4. 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-2021-20730/ (Markdown: https://insights.sbomify.com/CVE-2021-20730/index.md)","id":"CVE-2021-20730","markdown":"https://insights.sbomify.com/CVE-2021-20730/index.md","name":"CVE-2021-20730","record":{"aliases":["GHSA-g265-pf9w-jhwr"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Buffalo WiFi router","requires_auth":"none","summary":"An attacker can obtain configuration information from Buffalo WSR-1166DHP3 and WSR-1166DHP4 routers due to improper access control.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"wsr-1166dhp3_firmware","vendor":"buffalo"},{"product":"wsr-1166dhp4_firmware","vendor":"buffalo"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[],"description":"Improper access control vulnerability in WSR-1166DHP3 firmware Ver.1.16 and prior and WSR-1166DHP4 firmware Ver.1.02 and prior allows an attacker to obtain configuration information 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":"Information disclosure in WSR-1166DHP3 and WSR-1166DHP4","id":"CVE-2021-20730","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Command injection in WSR-1166DHP3 and WSR-1166DHP4","id":"CVE-2021-20731"},"packages":[],"prev":{"headline":"Cross-site scripting in pfSense CE and pfSense Plus","id":"CVE-2021-20729"},"products":["WSR-1166DHP3 and WSR-1166DHP4"],"published":"2021-06-09","related":[{"cvss_score":8.8,"headline":"Command injection in WSR-1166DHP3 and WSR-1166DHP4","id":"CVE-2021-20731","kev_date_added":null,"published":"2021-06-09"}],"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":"2024-08-03","vendors":["BUFFALO INC."]},"summary":"An attacker can obtain configuration information from Buffalo WSR-1166DHP3 and WSR-1166DHP4 routers due to improper access control.","url":"https://insights.sbomify.com/CVE-2021-20730/"}
