An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-3346 and fix it if it is affected.\n\nWhat it is: CVE-2023-3346 is a critical memory corruption vulnerability in MITSUBISHI CNC C80 Series C80, published on 3 Aug 2023. 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-2023-3346 in the wild and no public exploit code.\n\nAffected product: MITSUBISHI CNC C80 Series C80. 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-2023-3346/ (Markdown: https://insights.sbomify.com/CVE-2023-3346/index.md)","id":"CVE-2023-3346","markdown":"https://insights.sbomify.com/CVE-2023-3346/index.md","name":"CVE-2023-3346","record":{"aliases":["GHSA-whh9-m2fc-3q2v"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mitsubishi CNC controller","requires_auth":"none","summary":"Remote unauthenticated attackers can cause denial of service and execute arbitrary code on Mitsubishi CNC systems via crafted packets.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mitsubishi","cpe":[{"product":"c80_firmware","vendor":"mitsubishielectric"},{"product":"e70_firmware","vendor":"mitsubishielectric"},{"product":"e80_firmware","vendor":"mitsubishielectric"},{"product":"m70v_firmware","vendor":"mitsubishielectric"},{"product":"m720vs_15-type_firmware","vendor":"mitsubishielectric"},{"product":"m720vs_firmware","vendor":"mitsubishielectric"},{"product":"m720vw_firmware","vendor":"mitsubishielectric"},{"product":"m730vs_15-type_firmware","vendor":"mitsubishielectric"},{"product":"m730vs_firmware","vendor":"mitsubishielectric"},{"product":"m730vw_firmware","vendor":"mitsubishielectric"},{"product":"m750vs_15-type_firmware","vendor":"mitsubishielectric"},{"product":"m750vs_firmware","vendor":"mitsubishielectric"},{"product":"m750vw_firmware","vendor":"mitsubishielectric"},{"product":"m800s_firmware","vendor":"mitsubishielectric"},{"product":"m800vs_firmware","vendor":"mitsubishielectric"},{"product":"m800vw_firmware","vendor":"mitsubishielectric"},{"product":"m800w_firmware","vendor":"mitsubishielectric"},{"product":"m80_firmware","vendor":"mitsubishielectric"},{"product":"m80v_firmware","vendor":"mitsubishielectric"},{"product":"m80vw_firmware","vendor":"mitsubishielectric"},{"product":"m80w_firmware","vendor":"mitsubishielectric"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in MITSUBSHI CNC Series allows a remote unauthenticated attacker to cause Denial of Service (DoS) condition and execute arbitrary code on the product by sending specially crafted packets.
