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-2025-40946 and fix it if it is affected.\n\nWhat it is: CVE-2025-40946 is a high-severity vulnerability in Siemens blueplanet 100 NX3 M8, published on 12 May 2026. 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-2025-40946 in the wild and no public exploit code.\n\nAffected product: Siemens blueplanet 100 NX3 M8. 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-2025-40946/ (Markdown: https://insights.sbomify.com/CVE-2025-40946/index.md)","id":"CVE-2025-40946","markdown":"https://insights.sbomify.com/CVE-2025-40946/index.md","name":"CVE-2025-40946","record":{"aliases":["GHSA-5pqm-29j4-2vjr"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Siemens blueplanet inverters","requires_auth":"none","summary":"Attackers can derive Technical Service credentials from device serial numbers using a weak CRC16 algorithm to gain unauthorized access to Siemens blueplanet inverters.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-321","name":"Use of Hard-coded Cryptographic Key"}],"description":"A vulnerability has been identified in blueplanet 100 NX3 M8 (All versions), blueplanet 100 TL3 GEN2 (All versions \u003c V6.1.4.9), blueplanet 105 TL3 (All versions \u003c V3.92), blueplanet 105 TL3 GEN2 (All versions \u003c V6.1.4.9), blueplanet 110 TL3 (All versions \u003c V3.92), blueplanet 125 NX3 M10 (All versions), blueplanet 125 TL3 (All versions \u003c V3.92), blueplanet 125 TL3 GEN2 (All versions \u003c V6.1.4.9), blueplanet 137 TL3 (All versions \u003c V3.92), blueplanet 150 TL3 (All versions \u003c V3.92), blueplanet 150 TL3 GEN2 (All versions \u003c V6.1.4.9), blueplanet 155 TL3 (All versions \u003c V3.92), blueplanet 155 TL3 GEN2 (All versions \u003c V6.1.4.9), blueplanet 165 TL3 (All versions \u003c V3.92), blueplanet 165 TL3 GEN2 (All versions \u003c V6.1.4.9), blueplanet 3.0 TL3-60.0 TL3 (All versions), blueplanet 87.0 TL3 (All versions \u003c V3.92), blueplanet 87.0 TL3 GEN2 (All versions \u003c V6.1.4.9), blueplanet 92.0 TL3 (All versions \u003c V3.92), blueplanet 92.0 TL3 GEN2 (All versions \u003c V6.1.4.9), blueplanet gridsave 110 TL3-S (All versions \u003c V3.91), blueplanet gridsave 137 TL3-S (All versions \u003c V3.91), blueplanet gridsave 92.0 TL3-S (All versions \u003c V3.91).
