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-2020-21733 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-2020-21733/ (Markdown: https://insights.sbomify.com/CVE-2020-21733/index.md)","id":"CVE-2020-21733","markdown":"https://insights.sbomify.com/CVE-2020-21733/index.md","name":"CVE-2020-21733","record":{"aliases":["GHSA-jq52-3fww-m362"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Sagemcom router","requires_auth":"none","summary":"Cross-site scripting vulnerability in Sagemcom F@ST3686 routers allows attackers to inject malicious scripts via specific diagnostic and configuration pages.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"f\\@st_3686_firmware","vendor":"sagemcom"}],"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":"Sagemcom F@ST3686 v1.0 HUN 3.97.0 has XSS via RgDiagnostics.asp, RgDdns.asp, RgFirewallEL.asp, RgVpnL2tpPptp.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-2020-21733","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-21783"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-21732"},"products":["n/a"],"published":"2020-09-14","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-29329","kev_date_added":null,"published":"2026-01-12"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-3304","kev_date_added":null,"published":"2021-01-26"},{"cvss_score":7.7,"headline":"Insufficient session timeout vulnerability in Sagemcom router","id":"CVE-2024-1623","kev_date_added":null,"published":"2024-03-14"}],"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":"2026-07-09","vendors":["n/a"]},"summary":"Cross-site scripting vulnerability in Sagemcom F@ST3686 routers allows attackers to inject malicious scripts via specific diagnostic and configuration pages.","url":"https://insights.sbomify.com/CVE-2020-21733/"}
