An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2025-40798 and fix it if it is affected.\n\nWhat it is: CVE-2025-40798 is a high-severity memory corruption vulnerability in Siemens SIMATIC PCS neo V4.1, published on 9 Sep 2025. 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-2025-40798 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-2025-40798/ (Markdown: https://insights.sbomify.com/CVE-2025-40798/index.md)","id":"CVE-2025-40798","markdown":"https://insights.sbomify.com/CVE-2025-40798/index.md","name":"CVE-2025-40798","record":{"aliases":["GHSA-4prv-95gp-pq3p"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens PCS neo","requires_auth":"none","summary":"An unauthenticated remote attacker can cause a denial of service in Siemens SIMATIC PCS neo via an out-of-bounds read in the UMC component.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_pcs_neo","vendor":"siemens"},{"product":"user_management_component","vendor":"siemens"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"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), User Management Component (UMC) (All versions \u003c V2.15.1.3).
