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-2022-34302 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 10. 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-2022-34302/ (Markdown: https://insights.sbomify.com/CVE-2022-34302/index.md)","id":"CVE-2022-34302","markdown":"https://insights.sbomify.com/CVE-2022-34302/index.md","name":"CVE-2022-34302","record":{"aliases":["GHSA-77q2-m9gq-g982"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"New Horizon Datasys bootloader","requires_auth":"high_privilege","summary":"Attackers can bypass Secure Boot and execute arbitrary code by replacing the signed bootloader, requiring access to the EFI System Partition.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"uefi_bootloader","vendor":"horizondatasys"},{"product":"windows_10","vendor":"microsoft"},{"product":"windows_11","vendor":"microsoft"},{"product":"windows_8.1","vendor":"microsoft"},{"product":"windows_rt_8.1","vendor":"microsoft"},{"product":"windows_server_2012","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"},{"product":"windows_server_2022","vendor":"microsoft"},{"product":"enterprise_linux","vendor":"redhat"}],"cvss":{"score":6.7,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"A flaw was found in New Horizon Datasys bootloaders before 2022-06-01.
