It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-3928 in the wild and no public exploit code.\n\nAffected product: GeoVision Door Access Control Device. 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-2020-3928/ (Markdown: https://insights.sbomify.com/CVE-2020-3928/index.md)","id":"CVE-2020-3928","markdown":"https://insights.sbomify.com/CVE-2020-3928/index.md","name":"CVE-2020-3928","record":{"aliases":["GHSA-6mrh-38f8-gpcf"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["privilege_escalation","account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Door Access Control Device","requires_auth":"none","summary":"Attackers can gain root access to GeoVision Door Access Control devices using a hardcoded password shared across all units.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","cpe":[{"product":"geovision_gv-as1010_firmware","vendor":"usavisionsys"},{"product":"geovision_gv-as210_firmware","vendor":"usavisionsys"},{"product":"geovision_gv-as410_firmware","vendor":"usavisionsys"},{"product":"geovision_gv-as810_firmware","vendor":"usavisionsys"},{"product":"geovision_gv-gf192x_firmware","vendor":"usavisionsys"}],"cvss":{"score":6.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"}],"description":"GeoVision Door Access Control device family is hardcoded with a root password, which adopting an identical password in all devices.","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":"GeoVision Door Access Control Device - Hardcoded privileged password","id":"CVE-2020-3928","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"GeoVision Door Access Control Device - Shared cryptographic keys","id":"CVE-2020-3929"},"packages":[],"prev":{"headline":"ServiSign Windows Versions- Arbitrary File Deletion","id":"CVE-2020-3927"},"products":["Door Access Control Device"],"published":"2020-06-12","related":[{"cvss_score":5.9,"headline":"GeoVision Door Access Control Device - Shared cryptographic keys","id":"CVE-2020-3929","kev_date_added":null,"published":"2020-06-12"}],"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":"2024-09-17","vendors":["GeoVision"]},"summary":"Attackers can gain root access to GeoVision Door Access Control devices using a hardcoded password shared across all units.","url":"https://insights.sbomify.com/CVE-2020-3928/"}
