SIPLUS variants), published on 11 Oct 2022. An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-40227 and fix it if it is affected.\n\nWhat it is: CVE-2022-40227 is a high-severity denial of service vulnerability in Siemens SIMATIC HMI Comfort Panels (incl. SIPLUS variants), published on 11 Oct 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-2022-40227 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC HMI Comfort Panels (incl. SIPLUS variants). 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-2022-40227/ (Markdown: https://insights.sbomify.com/CVE-2022-40227/index.md)","id":"CVE-2022-40227","markdown":"https://insights.sbomify.com/CVE-2022-40227/index.md","name":"CVE-2022-40227","record":{"aliases":["GHSA-3w5w-5g86-h65c"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens HMI panels","requires_auth":"none","summary":"Unauthenticated remote attackers can cause permanent denial of service on Siemens HMI panels by sending crafted TCP packets, requiring device reboot.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_hmi_comfort_panels_firmware","vendor":"siemens"},{"product":"simatic_hmi_ktp1200_basic_firmware","vendor":"siemens"},{"product":"simatic_hmi_ktp400_basic_firmware","vendor":"siemens"},{"product":"simatic_hmi_ktp700_basic_firmware","vendor":"siemens"},{"product":"simatic_hmi_ktp900_basic_firmware","vendor":"siemens"},{"product":"simatic_hmi_ktp_mobile_panels_firmware","vendor":"siemens"},{"product":"siplus_hmi_ktp1200_basic_firmware","vendor":"siemens"},{"product":"siplus_hmi_ktp400_basic_firmware","vendor":"siemens"},{"product":"siplus_hmi_ktp700_basic_firmware","vendor":"siemens"},{"product":"siplus_hmi_ktp900_basic_firmware","vendor":"siemens"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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-20","name":"Improper Input Validation"}],"description":"A vulnerability has been identified in SIMATIC HMI Comfort Panels (incl.
