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-2024-54678 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC PCS neo V4.1. 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-2024-54678/ (Markdown: https://insights.sbomify.com/CVE-2024-54678/index.md)","id":"CVE-2024-54678","markdown":"https://insights.sbomify.com/CVE-2024-54678/index.md","name":"CVE-2024-54678","record":{"aliases":["GHSA-h4qr-6jj2-9qg8"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Siemens industrial automation","requires_auth":"low_privilege","summary":"An authenticated local attacker can execute arbitrary code via type confusion in IPC input handling across multiple Siemens industrial automation products.","user_interaction":"required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[],"cvss":{"score":8.6,"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:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"A vulnerability has been identified in SIMATIC PCS neo V4.1 (All versions), SIMATIC PCS neo V5.0 (All versions), SIMATIC PCS neo V6.0 (All versions \u003c V6.0 SP1 Update 1), SIMATIC S7-PLCSIM V17 (All versions), SIMATIC STEP 7 V17 (All versions \u003c V17 Update 9), SIMATIC STEP 7 V18 (All versions \u003c V18 Update 6), SIMATIC STEP 7 V19 (All versions \u003c V19 Update 4), SIMATIC STEP 7 V20 (All versions \u003c V20 Update 4), SIMATIC WinCC V17 (All versions \u003c V17 Update 9), SIMATIC WinCC V18 (All versions \u003c V18 Update 6), SIMATIC WinCC V19 (All versions \u003c V19 Update 4), SIMATIC WinCC V20 (All versions \u003c V20 Update 4), SIMOCODE ES V17 (All versions), SIMOCODE ES V18 (All versions), SIMOCODE ES V19 (All versions), SIMOCODE ES V20 (All versions), SIMOTION SCOUT TIA V5.4 (All versions), SIMOTION SCOUT TIA V5.5 (All versions), SIMOTION SCOUT TIA V5.6 (All versions \u003c V5.6 SP1 HF7), SIMOTION SCOUT TIA V5.7 (All versions), SINAMICS Startdrive V17 (All versions), SINAMICS Startdrive V18 (All versions), SINAMICS Startdrive V19 (All versions), SINAMICS Startdrive V20 (All versions), SIRIUS Safety ES V17 (TIA Portal) (All versions), SIRIUS Safety ES V18 (TIA Portal) (All versions), SIRIUS Safety ES V19 (TIA Portal) (All versions), SIRIUS Safety ES V20 (TIA Portal) (All versions), SIRIUS Soft Starter ES V17 (TIA Portal) (All versions), SIRIUS Soft Starter ES V18 (TIA Portal) (All versions), SIRIUS Soft Starter ES V19 (TIA Portal) (All versions), SIRIUS Soft Starter ES V20 (TIA Portal) (All versions), TIA Portal Cloud V17 (All versions), TIA Portal Cloud V18 (All versions \u003c V6.3.0.2), TIA Portal Cloud V19 (All versions \u003c V5.2.1.1), TIA Portal Cloud V20 (All versions \u003c V5.2.2.2), TIA Portal Test Suite V20 (All versions \u003c V20 Update 4).
