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-2022-41648 in the wild and no public exploit code.\n\nAffected product: HEIDENHAIN Controller TNC 640 NC Software. 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-2022-41648/ (Markdown: https://insights.sbomify.com/CVE-2022-41648/index.md)","id":"CVE-2022-41648","markdown":"https://insights.sbomify.com/CVE-2022-41648/index.md","name":"CVE-2022-41648","record":{"aliases":["GHSA-jc9h-j7vp-j9jw"],"analysis":{"component_type":"ics_ot","fix_type":"configuration_change","impacts":["denial_of_service","data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"CNC controller software","requires_auth":"none","summary":"Attackers can bypass authentication in DNC communication to disrupt production, steal data, or alter products if DNC is enabled.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"heros","vendor":"heidenhain"},{"product":"tnc_640_programming_station","vendor":"heidenhain"}],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"}],"description":"The HEIDENHAIN Controller TNC 640 NC software Version 340590 07 SP5, is vulnerable to improper authentication in its DNC communication for CNC machines.
