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-2022-33939 in the wild and no public exploit code.\n\nAffected product: Yokogawa Electric Corporation CENTUM VP / CS 3000 controller FCS. 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-2022-33939/ (Markdown: https://insights.sbomify.com/CVE-2022-33939/index.md)","id":"CVE-2022-33939","markdown":"https://insights.sbomify.com/CVE-2022-33939/index.md","name":"CVE-2022-33939","record":{"aliases":["GHSA-hg36-5628-7f89"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Yokogawa CENTUM VP","requires_auth":"none","summary":"An attacker can cause a denial of service in Yokogawa CENTUM VP/CS 3000 controllers by sending specially crafted communication packets.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"centum_cs_3000_cp31_firmware","vendor":"yokogawa"},{"product":"centum_cs_3000_cp33_firmware","vendor":"yokogawa"},{"product":"centum_cs_3000_cp345_firmware","vendor":"yokogawa"},{"product":"centum_cs_3000_cp401_firmware","vendor":"yokogawa"},{"product":"centum_cs_3000_cp451_firmware","vendor":"yokogawa"},{"product":"centum_vp_3000_cp401_firmware","vendor":"yokogawa"},{"product":"centum_vp_3000_cp451_firmware","vendor":"yokogawa"}],"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":[],"description":"CENTUM VP / CS 3000 controller FCS (CP31, CP33, CP345, CP401, and CP451) contains an issue in processing communication packets, which may lead to resource consumption.
