It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2023-32736 and fix it if it is affected.\n\nWhat it is: CVE-2023-32736 is a high-severity unsafe deserialization vulnerability in Siemens SIMATIC S7-PLCSIM V16, published on 12 Nov 2024. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-32736 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC S7-PLCSIM V16. 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-2023-32736/ (Markdown: https://insights.sbomify.com/CVE-2023-32736/index.md)","id":"CVE-2023-32736","markdown":"https://insights.sbomify.com/CVE-2023-32736/index.md","name":"CVE-2023-32736","record":{"aliases":["GHSA-5355-h7h8-637c"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Siemens TIA Portal","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary code in Siemens TIA Portal and related tools by exploiting improper input sanitization during user settings parsing.","user_interaction":"required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"A vulnerability has been identified in SIMATIC S7-PLCSIM V16 (All versions), SIMATIC S7-PLCSIM V17 (All versions), SIMATIC STEP 7 Safety V16 (All versions), SIMATIC STEP 7 Safety V17 (All versions \u003c V17 Update 8), SIMATIC STEP 7 Safety V18 (All versions \u003c V18 Update 5), SIMATIC STEP 7 V16 (All versions), SIMATIC STEP 7 V17 (All versions \u003c V17 Update 8), SIMATIC STEP 7 V18 (All versions \u003c V18 Update 5), SIMATIC WinCC Unified V16 (All versions), SIMATIC WinCC Unified V17 (All versions \u003c V17 Update 8), SIMATIC WinCC Unified V18 (All versions \u003c V18 SP5), SIMATIC WinCC V16 (All versions), SIMATIC WinCC V17 (All versions \u003c V17 Update 8), SIMATIC WinCC V18 (All versions \u003c V18 SP5), SIMOCODE ES V16 (All versions), SIMOCODE ES V17 (All versions \u003c V17 Update 8), SIMOCODE ES V18 (All versions), SIMOTION SCOUT TIA V5.4 SP1 (All versions), SIMOTION SCOUT TIA V5.4 SP3 (All versions), SIMOTION SCOUT TIA V5.5 SP1 (All versions), SINAMICS Startdrive V16 (All versions), SINAMICS Startdrive V17 (All versions), SINAMICS Startdrive V18 (All versions), SIRIUS Safety ES V17 (TIA Portal) (All versions \u003c V17 Update 8), SIRIUS Safety ES V18 (TIA Portal) (All versions), SIRIUS Soft Starter ES V17 (TIA Portal) (All versions \u003c V17 Update 8), SIRIUS Soft Starter ES V18 (TIA Portal) (All versions), TIA Portal Cloud V16 (All versions), TIA Portal Cloud V17 (All versions \u003c V4.6.0.1), TIA Portal Cloud V18 (All versions \u003c V4.6.1.0).
