An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-22724 and fix it if it is affected.\n\nWhat it is: CVE-2022-22724 is a high-severity denial of service vulnerability in Modicon M340 CPUs: BMXP34 (All Versions), published on 4 Feb 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-2022-22724 in the wild and no public exploit code.\n\nAffected product: Modicon M340 CPUs: BMXP34 (All Versions). 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-2022-22724/ (Markdown: https://insights.sbomify.com/CVE-2022-22724/index.md)","id":"CVE-2022-22724","markdown":"https://insights.sbomify.com/CVE-2022-22724/index.md","name":"CVE-2022-22724","record":{"aliases":["GHSA-qj7j-w6m6-7fgc"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Modicon PLC","requires_auth":"none","summary":"Attackers can cause denial of service on Modicon M340 PLCs by flooding TCP ports with RST or FIN packets, disrupting industrial operations.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"modicon_m340_bmxp341000_firmware","vendor":"schneider-electric"},{"product":"modicon_m340_bmxp342000_firmware","vendor":"schneider-electric"},{"product":"modicon_m340_bmxp3420102_firmware","vendor":"schneider-electric"},{"product":"modicon_m340_bmxp342010_firmware","vendor":"schneider-electric"},{"product":"modicon_m340_bmxp3420302_firmware","vendor":"schneider-electric"},{"product":"modicon_m340_bmxp342030_firmware","vendor":"schneider-electric"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A CWE-400: Uncontrolled Resource Consumption vulnerability exists that could cause a denial of service on ports 80 (HTTP) and 502 (Modbus), when sending a large number of TCP RST or FIN packets to any open TCP port of the PLC.
