SIPLUS variants), published on 14 Jul 2020. An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-7593 and fix it if it is affected.\n\nWhat it is: CVE-2020-7593 is a critical memory corruption vulnerability in Siemens AG LOGO! 8 BM (incl. SIPLUS variants), published on 14 Jul 2020. 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-2020-7593 in the wild and no public exploit code.\n\nAffected product: Siemens AG 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-2020-7593/ (Markdown: https://insights.sbomify.com/CVE-2020-7593/index.md)","id":"CVE-2020-7593","markdown":"https://insights.sbomify.com/CVE-2020-7593/index.md","name":"CVE-2020-7593","record":{"aliases":["GHSA-x26m-wcf2-85xw"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens LOGO! 8 BM","requires_auth":"none","summary":"A remote unauthenticated attacker can trigger a buffer overflow in the web server to achieve remote code execution on Siemens LOGO! 8 BM devices.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"logo\\!_8_bm_firmware","vendor":"siemens"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A vulnerability has been identified in LOGO! 8 BM (incl.
