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-2021-34207 in the wild and no public exploit code.\n\nAffected product: Totolink A3002r Firmware. 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-2021-34207/ (Markdown: https://insights.sbomify.com/CVE-2021-34207/index.md)","id":"CVE-2021-34207","markdown":"https://insights.sbomify.com/CVE-2021-34207/index.md","name":"CVE-2021-34207","record":{"aliases":["GHSA-4484-7jwf-xv44"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TOTOLINK router","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript in TOTOLINK A3002R routers via cross-site scripting in the DDNS configuration fields.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"a3002r_firmware","vendor":"totolink"}],"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 in ddns.htm in TOTOLINK A3002R version V1.1.1-B20200824 (Important Update, new UI) allows attackers to execute arbitrary JavaScript by modifying the \"Domain Name\" field, \"Server Address\" field, \"User Name/Email\", or \"Password/Key\" field.","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 n/a","id":"CVE-2021-34207","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"totolink:a3002r_firmware","products":["totolink:a3002r_firmware"],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-34215"},"packages":[],"prev":{"headline":"Hardcoded credentials in n/a","id":"CVE-2021-34204"},"products":["n/a"],"published":"2021-08-20","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2025-55591","kev_date_added":null,"published":"2025-08-18"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2025-45858","kev_date_added":null,"published":"2025-05-13"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-45861","kev_date_added":null,"published":"2025-05-13"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-45863","kev_date_added":null,"published":"2025-05-13"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-45865","kev_date_added":null,"published":"2025-05-13"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2025-25579","kev_date_added":null,"published":"2025-03-28"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-42520","kev_date_added":null,"published":"2024-08-12"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can execute arbitrary JavaScript in TOTOLINK A3002R routers via cross-site scripting in the DDNS configuration fields.","url":"https://insights.sbomify.com/CVE-2021-34207/"}
