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-2021-43661 in the wild and no public exploit code.\n\nAffected product: n/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-2021-43661/ (Markdown: https://insights.sbomify.com/CVE-2021-43661/index.md)","id":"CVE-2021-43661","markdown":"https://insights.sbomify.com/CVE-2021-43661/index.md","name":"CVE-2021-43661","record":{"aliases":["GHSA-hg29-53rh-m9vp"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"TOTOLink router","requires_auth":"none","summary":"A reflected cross-site scripting vulnerability in the TOTOLink EX300_v2 router allows attackers to inject malicious scripts via the home.asp component.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ex300_v2_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":"totolink EX300_v2 V4.0.3c.140_B20210429 was discovered to contain a reflected cross-site scripting (XSS) vulnerability via the component /home.asp.","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-2021-43661","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-43662"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-43659"},"products":["n/a"],"published":"2022-03-30","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2022-32449","kev_date_added":null,"published":"2022-07-07"},{"cvss_score":8.1,"headline":"Command injection in n/a","id":"CVE-2021-43664","kev_date_added":null,"published":"2022-03-30"},{"cvss_score":7.5,"headline":"Command injection in n/a","id":"CVE-2021-43663","kev_date_added":null,"published":"2022-03-30"}],"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":"A reflected cross-site scripting vulnerability in the TOTOLink EX300_v2 router allows attackers to inject malicious scripts via the home.asp component.","url":"https://insights.sbomify.com/CVE-2021-43661/"}
