An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2016-9158 and fix it if it is affected.\n\nWhat it is: CVE-2016-9158 is a high-severity denial of service vulnerability in Siemens AG SIMATIC S7-300 CPU family, published on 17 Dec 2016. 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-2016-9158 in the wild and no public exploit code.\n\nAffected product: Siemens AG SIMATIC S7-300 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-2016-9158/ (Markdown: https://insights.sbomify.com/CVE-2016-9158/index.md)","id":"CVE-2016-9158","markdown":"https://insights.sbomify.com/CVE-2016-9158/index.md","name":"CVE-2016-9158","record":{"aliases":["GHSA-pmf4-x4c5-385f"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens SIMATIC PLC","requires_auth":"none","summary":"Specially crafted packets sent to port 80 cause Siemens SIMATIC S7-300/400 CPUs to enter defect mode, requiring a cold restart to recover.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_s7-300_cpu_firmware","vendor":"siemens"},{"product":"simatic_s7-400_cpu_firmware","vendor":"siemens"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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-20","name":"Improper Input Validation"}],"description":"A vulnerability has been identified in SIMATIC S7-300 CPU family (All versions), SIMATIC S7-300 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions), SIMATIC S7-400 PN/DP V6 and below CPU family (incl.
