WRC-1467GHBK-A, published on 12 Feb 2021. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-20644 in the wild and no public exploit code.\n\nAffected product: ELECOM CO.,LTD. WRC-1467GHBK-A. 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-2021-20644/ (Markdown: https://insights.sbomify.com/CVE-2021-20644/index.md)","id":"CVE-2021-20644","markdown":"https://insights.sbomify.com/CVE-2021-20644/index.md","name":"CVE-2021-20644","record":{"aliases":["GHSA-chg9-84gg-7qpw"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Wireless router","requires_auth":"none","summary":"Attackers can execute arbitrary scripts in users' browsers via a crafted SSID on the router's web setup page.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"wrc-1467ghbk-a_firmware","vendor":"elecom"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"ELECOM WRC-1467GHBK-A allows arbitrary scripts to be executed on the user's web browser by displaying a specially crafted SSID on the web setup page.","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":"Cross-site scripting in WRC-1467GHBK-A","id":"CVE-2021-20644","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in WRC-300FEBK-A","id":"CVE-2021-20645"},"packages":[],"prev":{"headline":"Missing authorization in LD-PS/U1","id":"CVE-2021-20643"},"products":["WRC-1467GHBK-A"],"published":"2021-02-12","related":[{"cvss_score":8.8,"headline":"Code injection in LAN-WH300N/RE","id":"CVE-2023-39445","kev_date_added":null,"published":"2023-08-18"},{"cvss_score":8.8,"headline":"Command injection in WRC-1467GHBK-A","id":"CVE-2023-39455","kev_date_added":null,"published":"2023-08-18"}],"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":["ELECOM CO.,LTD."]},"summary":"Attackers can execute arbitrary scripts in users' browsers via a crafted SSID on the router's web setup page.","url":"https://insights.sbomify.com/CVE-2021-20644/"}
