An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-49252 and fix it if it is affected.\n\nWhat it is: CVE-2023-49252 is a high-severity missing authorization vulnerability in Siemens SIMATIC CN 4100, published on 9 Jan 2024. 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-2023-49252 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-2023-49252/ (Markdown: https://insights.sbomify.com/CVE-2023-49252/index.md)","id":"CVE-2023-49252","markdown":"https://insights.sbomify.com/CVE-2023-49252/index.md","name":"CVE-2023-49252","record":{"aliases":["GHSA-qv7h-cgx5-jj9m"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial network device","requires_auth":"none","summary":"An unauthenticated attacker can change IP configuration on SIMATIC CN 4100 devices, potentially causing a denial of service condition.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_cn_4100_firmware","vendor":"siemens"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability has been identified in SIMATIC CN 4100 (All versions \u003c V2.7).
