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-2021-42027 in the wild and no public exploit code.\n\nAffected product: Siemens SINUMERIK Edge. 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-2021-42027/ (Markdown: https://insights.sbomify.com/CVE-2021-42027/index.md)","id":"CVE-2021-42027","markdown":"https://insights.sbomify.com/CVE-2021-42027/index.md","name":"CVE-2021-42027","record":{"aliases":["GHSA-qf34-j4vq-q329"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"SINUMERIK Edge","requires_auth":"none","summary":"An attacker can spoof a trusted entity by interfering in the communication path due to improper TLS certificate validation in SINUMERIK Edge.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"sinumerik_edge","vendor":"siemens"}],"cvss":{"score":7.4,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"A vulnerability has been identified in SINUMERIK Edge (All versions \u003c V3.2).
