ACERA 1310, published on 3 Oct 2023. 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-2023-42771 in the wild and no public exploit code.\n\nAffected product: FURUNO SYSTEMS Co.,Ltd. ACERA 1310. 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-2023-42771/ (Markdown: https://insights.sbomify.com/CVE-2023-42771/index.md)","id":"CVE-2023-42771","markdown":"https://insights.sbomify.com/CVE-2023-42771/index.md","name":"CVE-2023-42771","record":{"aliases":["GHSA-j2mj-6c7w-rh5m"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Marine radar system","requires_auth":"none","summary":"An unauthenticated network-adjacent attacker can bypass authentication to download or upload configuration and firmware files in standalone mode.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"acera_1310_firmware","vendor":"furunosystems"},{"product":"acera_1320_firmware","vendor":"furunosystems"}],"cvss":{"score":8.3,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"Authentication bypass vulnerability in ACERA 1320 firmware ver.01.26 and earlier, and ACERA 1310 firmware ver.01.26 and earlier allows a network-adjacent unauthenticated attacker who can access the affected product to download configuration files and/or log files, and upload configuration files and/or firmware.
