Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-20128 in the wild and no public exploit code.\n\nAffected product: Draytek VigorConnect. 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-2021-20128/ (Markdown: https://insights.sbomify.com/CVE-2021-20128/index.md)","id":"CVE-2021-20128","markdown":"https://insights.sbomify.com/CVE-2021-20128/index.md","name":"CVE-2021-20128","record":{"aliases":["GHSA-vj36-fv2g-fcfx"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Draytek VigorConnect","requires_auth":"low_privilege","summary":"Stored XSS in Draytek VigorConnect allows attackers to inject malicious scripts via the Profile Name field, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"vigorconnect","vendor":"draytek"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"The Profile Name field in the floor plan (Network Menu) page in Draytek VigorConnect 1.6.0-B3 was found to be vulnerable to stored XSS, as user input is not properly sanitized.","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 Draytek VigorConnect","id":"CVE-2021-20128","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in Draytek VigorConnect","id":"CVE-2021-20129"},"packages":[],"prev":{"headline":"Path traversal in Draytek VigorConnect","id":"CVE-2021-20127"},"products":["Draytek VigorConnect"],"published":"2021-10-13","related":[{"cvss_score":7.5,"headline":"Draytek VigorConnect Path Traversal Vulnerability","id":"CVE-2021-20123","kev_date_added":"2024-09-03","published":"2021-10-13"},{"cvss_score":7.5,"headline":"Draytek VigorConnect Path Traversal Vulnerability","id":"CVE-2021-20124","kev_date_added":"2024-09-03","published":"2021-10-13"},{"cvss_score":9.8,"headline":"File upload in Draytek VigorConnect","id":"CVE-2021-20125","kev_date_added":null,"published":"2021-10-13"},{"cvss_score":8.8,"headline":"Cross-site request forgery in Draytek VigorConnect","id":"CVE-2021-20126","kev_date_added":null,"published":"2021-10-13"},{"cvss_score":8.1,"headline":"Path traversal in Draytek VigorConnect","id":"CVE-2021-20127","kev_date_added":null,"published":"2021-10-13"},{"cvss_score":7.5,"headline":"Information disclosure in Draytek VigorConnect","id":"CVE-2021-20129","kev_date_added":null,"published":"2021-10-13"}],"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":["n/a"]},"summary":"Stored XSS in Draytek VigorConnect allows attackers to inject malicious scripts via the Profile Name field, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2021-20128/"}
