An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-35035 in the wild and no public exploit code.\n\nAffected product: Zyxel NBG6604 series 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-2021-35035/ (Markdown: https://insights.sbomify.com/CVE-2021-35035/index.md)","id":"CVE-2021-35035","markdown":"https://insights.sbomify.com/CVE-2021-35035/index.md","name":"CVE-2021-35035","record":{"aliases":["GHSA-778x-386c-73gw"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Zyxel router firmware","requires_auth":"high_privilege","summary":"Remote authenticated attackers can read sensitive information from the configuration file due to cleartext storage in Zyxel NBG6604 firmware.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"nbg6604_firmware","vendor":"zyxel"}],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-312","name":"Cleartext Storage of Sensitive Information"}],"description":"A cleartext storage of sensitive information vulnerability in the Zyxel NBG6604 firmware could allow a remote, authenticated attacker to obtain sensitive information from the configuration file.","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":"Information disclosure in NBG6604 series firmware","id":"CVE-2021-35035","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in VMG3625-T50B firmware","id":"CVE-2021-35036"},"packages":[],"prev":{"headline":"Security feature bypass in NBG6604 series firmware","id":"CVE-2021-35034"},"products":["NBG6604 series firmware"],"published":"2021-12-29","related":[{"cvss_score":8.8,"headline":"Command injection in NBG6604 firmware","id":"CVE-2023-33013","kev_date_added":null,"published":"2023-08-14"},{"cvss_score":8.8,"headline":"Command injection in NBG6604 firmware","id":"CVE-2023-22919","kev_date_added":null,"published":"2023-05-01"},{"cvss_score":7.4,"headline":"Security feature bypass in NBG6604 series firmware","id":"CVE-2021-35034","kev_date_added":null,"published":"2021-12-29"}],"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":["Zyxel"]},"summary":"Remote authenticated attackers can read sensitive information from the configuration file due to cleartext storage in Zyxel NBG6604 firmware.","url":"https://insights.sbomify.com/CVE-2021-35035/"}
