An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-7584 and fix it if it is affected.\n\nWhat it is: CVE-2020-7584 is a high-severity denial of service vulnerability in Siemens AG SIMATIC S7-200 SMART CPU family, published on 14 Jul 2020. 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-2020-7584 in the wild and no public exploit code.\n\nAffected product: Siemens AG SIMATIC S7-200 SMART CPU family. 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-2020-7584/ (Markdown: https://insights.sbomify.com/CVE-2020-7584/index.md)","id":"CVE-2020-7584","markdown":"https://insights.sbomify.com/CVE-2020-7584/index.md","name":"CVE-2020-7584","record":{"aliases":["GHSA-vpvj-7qfp-4qgg"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens PLC","requires_auth":"none","summary":"An attacker can cause a Denial-of-Service by overwhelming the device with incoming connections, affecting Siemens SIMATIC S7-200 SMART CPUs.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_s7-200_smart_sr_cpu_firmware","vendor":"siemens"},{"product":"simatic_s7-200_smart_st_cpu_firmware","vendor":"siemens"}],"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 vulnerability has been identified in SIMATIC S7-200 SMART CPU family (All versions \u003e= V2.2 \u003c V2.5.1).
