It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-25234 and fix it if it is affected.\n\nWhat it is: CVE-2020-25234 is a high-severity vulnerability in Siemens LOGO! 8 BM (incl. SIPLUS variants), published on 14 Dec 2020. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-25234 in the wild and no public exploit code.\n\nAffected product: Siemens LOGO! 8 BM (incl. SIPLUS variants). 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-2020-25234/ (Markdown: https://insights.sbomify.com/CVE-2020-25234/index.md)","id":"CVE-2020-25234","markdown":"https://insights.sbomify.com/CVE-2020-25234/index.md","name":"CVE-2020-25234","record":{"aliases":["GHSA-66q5-93c3-xq5w"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Siemens LOGO!
