It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2016-20029 exists.\n\nAffected product: ZKTeco ZKBioSecurity. 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-2016-20029/ (Markdown: https://insights.sbomify.com/CVE-2016-20029/index.md)","id":"CVE-2016-20029","markdown":"https://insights.sbomify.com/CVE-2016-20029/index.md","name":"CVE-2016-20029","record":{"aliases":["GHSA-qwpg-chxq-r7gf"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ZKTeco ZKBioSecurity","requires_auth":"none","summary":"Attackers can manipulate file paths to bypass access controls and retrieve sensitive information such as configuration files and source code.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"ZKTeco ZKBioSecurity 3.0 contains a file path manipulation vulnerability that allows attackers to access arbitrary files by modifying file paths used to retrieve local resources.
