An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-47374 and fix it if it is affected.\n\nWhat it is: CVE-2022-47374 is a high-severity denial of service vulnerability in Siemens SIMATIC S7-400 CPU 412-2 PN V7, published on 12 Dec 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-2022-47374 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC S7-400 CPU 412-2 PN V7. 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-2022-47374/ (Markdown: https://insights.sbomify.com/CVE-2022-47374/index.md)","id":"CVE-2022-47374","markdown":"https://insights.sbomify.com/CVE-2022-47374/index.md","name":"CVE-2022-47374","record":{"aliases":["GHSA-cr2v-p345-fp24"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens PLCs","requires_auth":"none","summary":"Attackers can exhaust system resources via HTTP requests, causing denial of service on Siemens SIMATIC and SINAMICS devices.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"6ag1414-3em07-7ab0_firmware","vendor":"siemens"},{"product":"6ag1416-3es07-7ab0_firmware","vendor":"siemens"},{"product":"6es7412-2ek07-0ab0_firmware","vendor":"siemens"},{"product":"6es7414-3em07-0ab0_firmware","vendor":"siemens"},{"product":"6es7414-3fm07-0ab0_firmware","vendor":"siemens"},{"product":"6es7416-3es07-0ab0_firmware","vendor":"siemens"},{"product":"6es7416-3fs07-0ab0_firmware","vendor":"siemens"},{"product":"simatic_pc-station_plus_firmware","vendor":"siemens"},{"product":"sinamics_s120_firmware","vendor":"siemens"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"}],"description":"A vulnerability has been identified in SIMATIC PC-Station Plus (All versions), SIMATIC S7-400 CPU 412-2 PN V7 (All versions), SIMATIC S7-400 CPU 414-3 PN/DP V7 (All versions), SIMATIC S7-400 CPU 414F-3 PN/DP V7 (All versions), SIMATIC S7-400 CPU 416-3 PN/DP V7 (All versions), SIMATIC S7-400 CPU 416F-3 PN/DP V7 (All versions), SINAMICS S120 (incl.
