An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-40356 and fix it if it is affected.\n\nWhat it is: CVE-2021-40356 is a high-severity vulnerability in Siemens Teamcenter Visualization, published on 14 Sep 2021. 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-2021-40356 in the wild and no public exploit code.\n\nAffected product: Siemens Teamcenter Visualization. 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-2021-40356/ (Markdown: https://insights.sbomify.com/CVE-2021-40356/index.md)","id":"CVE-2021-40356","markdown":"https://insights.sbomify.com/CVE-2021-40356/index.md","name":"CVE-2021-40356","record":{"aliases":["GHSA-7xwv-xhf6-x5cr"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens Teamcenter","requires_auth":"none","summary":"An attacker can exploit an XML External Entity injection flaw in Siemens Teamcenter to view files on the application server filesystem.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"teamcenter_visualization","vendor":"siemens"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"A vulnerability has been identified in Teamcenter V12.4 (All versions \u003c V12.4.0.8), Teamcenter V13.0 (All versions \u003c V13.0.0.7), Teamcenter V13.1 (All versions \u003c V13.1.0.5), Teamcenter V13.2 (All versions \u003c 13.2.0.2).
