Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2025-40937 and fix it if it is affected.\n\nWhat it is: CVE-2025-40937 is a high-severity command injection vulnerability in Siemens SIMATIC CN 4100, published on 9 Dec 2025. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-40937 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC CN 4100. 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-2025-40937/ (Markdown: https://insights.sbomify.com/CVE-2025-40937/index.md)","id":"CVE-2025-40937","markdown":"https://insights.sbomify.com/CVE-2025-40937/index.md","name":"CVE-2025-40937","record":{"aliases":["GHSA-f729-p9c9-fm58"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial network device","requires_auth":"low_privilege","summary":"An authenticated attacker can execute arbitrary code with limited privileges via improper input validation in the REST API of SIMATIC CN 4100 devices.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_cn_4100_firmware","vendor":"siemens"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"A vulnerability has been identified in SIMATIC CN 4100 (All versions \u003c V4.0.1).
