An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-40265 and fix it if it is affected.\n\nWhat it is: CVE-2022-40265 is a high-severity denial of service vulnerability in Mitsubishi Electric Corporation MELSEC iQ-R Series R04/08/16/32/120ENCPU, published on 30 Nov 2022. 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-2022-40265 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric Corporation MELSEC iQ-R Series R04/08/16/32/120ENCPU. 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-2022-40265/ (Markdown: https://insights.sbomify.com/CVE-2022-40265/index.md)","id":"CVE-2022-40265","markdown":"https://insights.sbomify.com/CVE-2022-40265/index.md","name":"CVE-2022-40265","record":{"aliases":["GHSA-vgcx-cp27-7f7h"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mitsubishi PLC module","requires_auth":"none","summary":"Remote unauthenticated attackers can cause a denial of service in Mitsubishi MELSEC iQ-R Ethernet modules by sending crafted packets, requiring a system reset.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mitsubishi","cpe":[{"product":"r04encpu_firmware","vendor":"mitsubishielectric"},{"product":"r08encpu_firmware","vendor":"mitsubishielectric"},{"product":"r120encpu_firmware","vendor":"mitsubishielectric"},{"product":"r16encpu_firmware","vendor":"mitsubishielectric"},{"product":"r32encpu_firmware","vendor":"mitsubishielectric"},{"product":"rj71en71_firmware","vendor":"mitsubishielectric"}],"cvss":{"score":8.6,"severity":"high","source":"cna","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-20","name":"Improper Input Validation"}],"description":"Improper Input Validation vulnerability in Mitsubishi Electric Corporation MELSEC iQ-R Series RJ71EN71 Firmware version \"65\" and prior and Mitsubishi Electric Corporation MELSEC iQ-R Series R04/08/16/32/120ENCPU Network Part Firmware version \"65\" and prior allows a remote unauthenticated attacker to cause a Denial of Service condition by sending specially crafted packets.
