Wi-Fi STATION SH-52A, published on 1 Dec 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-2021-20847 in the wild and no public exploit code.\n\nAffected product: NTT DOCOMO, INC. Wi-Fi STATION SH-52A. 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-2021-20847/ (Markdown: https://insights.sbomify.com/CVE-2021-20847/index.md)","id":"CVE-2021-20847","markdown":"https://insights.sbomify.com/CVE-2021-20847/index.md","name":"CVE-2021-20847","record":{"aliases":["GHSA-5f3c-9rrr-9rp4"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Wi-Fi station device","requires_auth":"none","summary":"Remote attackers can inject arbitrary scripts via the WebUI of the Wi-Fi STATION SH-52A, potentially compromising user sessions or device integrity.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"wi-fi_station_sh-52a_firmware","vendor":"nttdocomo"}],"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-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross-site scripting vulnerability in Wi-Fi STATION SH-52A (38JP_1_11G, 38JP_1_11J, 38JP_1_11K, 38JP_1_11L, 38JP_1_26F, 38JP_1_26G, 38JP_1_26J, 38JP_2_03B, and 38JP_2_03C) allows a remote unauthenticated attacker to inject an arbitrary script via WebUI of the 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":"Cross-site scripting in Wi-Fi STATION SH-52A","id":"CVE-2021-20847","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 github.com/schollz/rwtxt","id":"CVE-2021-20848"},"packages":[],"prev":{"headline":"Cross-site request forgery in Push Notifications for WordPress (Lite)","id":"CVE-2021-20846"},"products":["Wi-Fi STATION SH-52A"],"published":"2021-12-01","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":"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":["NTT DOCOMO, INC."]},"summary":"Remote attackers can inject arbitrary scripts via the WebUI of the Wi-Fi STATION SH-52A, potentially compromising user sessions or device integrity.","url":"https://insights.sbomify.com/CVE-2021-20847/"}
