Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-46144 and fix it if it is affected.\n\nWhat it is: CVE-2022-46144 is a high-severity denial of service vulnerability in Siemens SCALANCE SC622-2C, published on 13 Dec 2022. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-46144 in the wild and no public exploit code.\n\nAffected product: Siemens SCALANCE SC622-2C. 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-2022-46144/ (Markdown: https://insights.sbomify.com/CVE-2022-46144/index.md)","id":"CVE-2022-46144","markdown":"https://insights.sbomify.com/CVE-2022-46144/index.md","name":"CVE-2022-46144","record":{"aliases":["GHSA-p939-r66p-8wwm"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens SCALANCE switch","requires_auth":"low_privilege","summary":"An authenticated attacker can cause a denial of service on the CLI interface by forcefully quitting an SSH connection.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"6gk5622-2gs00-2ac2_firmware","vendor":"siemens"},{"product":"6gk5626-2gs00-2ac2_firmware","vendor":"siemens"},{"product":"6gk5632-2gs00-2ac2_firmware","vendor":"siemens"},{"product":"6gk5636-2gs00-2ac2_firmware","vendor":"siemens"},{"product":"6gk5642-2gs00-2ac2_firmware","vendor":"siemens"},{"product":"6gk5646-2gs00-2ac2_firmware","vendor":"siemens"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-664","name":"Improper Control of a Resource Through its Lifetime"}],"description":"A vulnerability has been identified in SCALANCE SC622-2C (6GK5622-2GS00-2AC2) (All versions \u003c V2.3), SCALANCE SC622-2C (6GK5622-2GS00-2AC2) (All versions \u003e= V2.3 \u003c V3.0), SCALANCE SC626-2C (6GK5626-2GS00-2AC2) (All versions \u003c V2.3), SCALANCE SC626-2C (6GK5626-2GS00-2AC2) (All versions \u003e= V2.3 \u003c V3.0), SCALANCE SC632-2C (6GK5632-2GS00-2AC2) (All versions \u003c V2.3), SCALANCE SC632-2C (6GK5632-2GS00-2AC2) (All versions \u003e= V2.3 \u003c V3.0), SCALANCE SC636-2C (6GK5636-2GS00-2AC2) (All versions \u003c V2.3), SCALANCE SC636-2C (6GK5636-2GS00-2AC2) (All versions \u003e= V2.3 \u003c V3.0), SCALANCE SC642-2C (6GK5642-2GS00-2AC2) (All versions \u003c V2.3), SCALANCE SC642-2C (6GK5642-2GS00-2AC2) (All versions \u003e= V2.3 \u003c V3.0), SCALANCE SC646-2C (6GK5646-2GS00-2AC2) (All versions \u003c V2.3), SCALANCE SC646-2C (6GK5646-2GS00-2AC2) (All versions \u003e= V2.3 \u003c V3.0), SCALANCE WAM763-1 (6GK5763-1AL00-7DA0) (All versions \u003c V2.0.0), SCALANCE WAM766-1 (6GK5766-1GE00-7DA0) (All versions \u003c V2.0.0), SCALANCE WAM766-1 (US) (6GK5766-1GE00-7DB0) (All versions \u003c V2.0.0), SCALANCE WAM766-1 EEC (6GK5766-1GE00-7TA0) (All versions \u003c V2.0.0), SCALANCE WAM766-1 EEC (US) (6GK5766-1GE00-7TB0) (All versions \u003c V2.0.0), SCALANCE WUM763-1 (6GK5763-1AL00-3AA0) (All versions \u003c V2.0.0), SCALANCE WUM763-1 (6GK5763-1AL00-3DA0) (All versions \u003c V2.0.0), SCALANCE WUM766-1 (6GK5766-1GE00-3DA0) (All versions \u003c V2.0.0), SCALANCE WUM766-1 (USA) (6GK5766-1GE00-3DB0) (All versions \u003c V2.0.0).
