An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-37199 and fix it if it is affected.\n\nWhat it is: CVE-2021-37199 is a high-severity memory corruption vulnerability in Siemens SINUMERIK 808D, published on 12 Oct 2021. 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-2021-37199 in the wild and no public exploit code.\n\nAffected product: Siemens SINUMERIK 808D. 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-2021-37199/ (Markdown: https://insights.sbomify.com/CVE-2021-37199/index.md)","id":"CVE-2021-37199","markdown":"https://insights.sbomify.com/CVE-2021-37199/index.md","name":"CVE-2021-37199","record":{"aliases":["GHSA-q6gp-rmpv-2ghj"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens CNC controller","requires_auth":"none","summary":"An attacker can cause a denial-of-service on Siemens SINUMERIK CNC controllers by sending crafted packets to port 102/tcp.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"sinumerik_808d_firmware","vendor":"siemens"},{"product":"sinumerik_828d_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-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A vulnerability has been identified in SINUMERIK 808D (All versions), SINUMERIK 828D (All versions \u003c V4.95).
