It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-4030 in the wild and no public exploit code.\n\nAffected product: Zyxel ARMOR Z1 (NBG6816) 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-2021-4030/ (Markdown: https://insights.sbomify.com/CVE-2021-4030/index.md)","id":"CVE-2021-4030","markdown":"https://insights.sbomify.com/CVE-2021-4030/index.md","name":"CVE-2021-4030","record":{"aliases":["GHSA-f5hq-fhh6-8vh6"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zyxel ARMOR firmware","requires_auth":"none","summary":"An attacker can execute arbitrary commands on Zyxel ARMOR devices by tricking a local user into visiting a malicious website via CSRF.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"nbg6816_firmware","vendor":"zyxel"},{"product":"nbg6817_firmware","vendor":"zyxel"}],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"A cross-site request forgery vulnerability in the HTTP daemon of the Zyxel ARMOR Z1/Z2 firmware could allow an attacker to execute arbitrary commands if they coerce or trick a local user to visit a compromised website with malicious scripts.","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 request forgery in ARMOR Z1 (NBG6816) firmware","id":"CVE-2021-4030","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"csrf","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Syltek Insufficient Verification of Data Authenticity","id":"CVE-2021-4031"},"packages":[],"prev":{"headline":"Command injection in ARMOR Z1 (NBG6816) firmware","id":"CVE-2021-4029"},"products":["ARMOR Z1 (NBG6816) firmware","ARMOR Z2 (NBG6817) firmware"],"published":"2022-02-22","related":[{"cvss_score":8.8,"headline":"Command injection in ARMOR Z1 (NBG6816) firmware","id":"CVE-2021-4029","kev_date_added":null,"published":"2022-02-22"}],"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":["Zyxel"]},"summary":"An attacker can execute arbitrary commands on Zyxel ARMOR devices by tricking a local user into visiting a malicious website via CSRF.","url":"https://insights.sbomify.com/CVE-2021-4030/"}
