It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-43982 and fix it if it is affected.\n\nWhat it is: CVE-2021-43982 is a high-severity memory corruption vulnerability in Delta Electronics CNCSoft, published on 9 Dec 2021. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-43982 in the wild and no public exploit code.\n\nAffected product: Delta Electronics CNCSoft. 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-2021-43982/ (Markdown: https://insights.sbomify.com/CVE-2021-43982/index.md)","id":"CVE-2021-43982","markdown":"https://insights.sbomify.com/CVE-2021-43982/index.md","name":"CVE-2021-43982","record":{"aliases":["GHSA-cx3c-jf2w-95p5"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"CNC control software","requires_auth":"none","summary":"A stack-based buffer overflow in Delta Electronics CNCSoft allows attackers to execute arbitrary code, posing a risk to industrial control systems.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"cncsoft","vendor":"deltaww"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Delta Electronics CNCSoft Versions 1.01.30 and prior are vulnerable to a stack-based buffer overflow, which may allow an attacker to execute arbitrary code.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Delta Electronics CNCSoft","id":"CVE-2021-43982","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"WECON LeviStudioU","id":"CVE-2021-43983"},"packages":[],"prev":{"headline":"mySCADA myPRO","id":"CVE-2021-43981"},"products":["CNCSoft"],"published":"2021-12-09","related":[{"cvss_score":8.8,"headline":"Memory corruption in CNCSoft with ScreenEditor","id":"CVE-2018-10636","kev_date_added":null,"published":"2018-08-13"},{"cvss_score":8.1,"headline":"Memory corruption in CNCSoft with ScreenEditor","id":"CVE-2018-10598","kev_date_added":null,"published":"2018-08-13"},{"cvss_score":7.8,"headline":"CVE-2022-4634","id":"CVE-2022-4634","kev_date_added":null,"published":"2023-02-02"},{"cvss_score":7.8,"headline":"Delta Electronics CNCSoft Stack-based Buffer Overflow","id":"CVE-2022-1405","kev_date_added":null,"published":"2022-08-31"},{"cvss_score":7.3,"headline":"Out-of-bounds Write in CNCSoft","id":"CVE-2025-47724","kev_date_added":null,"published":"2025-06-04"},{"cvss_score":7.3,"headline":"Out-of-bounds Write in CNCSoft","id":"CVE-2025-47725","kev_date_added":null,"published":"2025-06-04"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["Delta Electronics"]},"summary":"A stack-based buffer overflow in Delta Electronics CNCSoft allows attackers to execute arbitrary code, posing a risk to industrial control systems.","url":"https://insights.sbomify.com/CVE-2021-43982/"}
