An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2016-8368 and fix it if it is affected.\n\nWhat it is: CVE-2016-8368 is a high-severity denial of service vulnerability in Mitsubishi Electric MELSEC-Q Series Ethernet Interface Module, published on 13 Feb 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-8368 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric MELSEC-Q Series Ethernet Interface Module. 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-2016-8368/ (Markdown: https://insights.sbomify.com/CVE-2016-8368/index.md)","id":"CVE-2016-8368","markdown":"https://insights.sbomify.com/CVE-2016-8368/index.md","name":"CVE-2016-8368","record":{"aliases":["GHSA-v2rq-g9fx-7mr6"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mitsubishi PLC interface","requires_auth":"none","summary":"Remote attackers can cause a denial of service on Mitsubishi MELSEC-Q PLCs by exploiting an unrestricted lock on the Ethernet interface, requiring a manual reset.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"qj71e71-100_firmware","vendor":"mitsubishielectric"},{"product":"qj71e71-b2_firmware","vendor":"mitsubishielectric"},{"product":"qj71e71-b5_firmware","vendor":"mitsubishielectric"}],"cvss":{"score":8.6,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-662","name":"Improper Synchronization"}],"description":"An issue was discovered in Mitsubishi Electric Automation MELSEC-Q series Ethernet interface modules QJ71E71-100, all versions, QJ71E71-B5, all versions, and QJ71E71-B2, all versions.
