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-2021-40159 in the wild and no public exploit code.\n\nAffected product: Autodesk Advance Steel. 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-2021-40159/ (Markdown: https://insights.sbomify.com/CVE-2021-40159/index.md)","id":"CVE-2021-40159","markdown":"https://insights.sbomify.com/CVE-2021-40159/index.md","name":"CVE-2021-40159","record":{"aliases":["GHSA-67q4-7j7w-j6hx"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["data_read","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Autodesk Inventor","requires_auth":"none","summary":"Attackers can exploit information disclosure in JT files to potentially achieve code execution in Autodesk Inventor.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"autodesk","cpe":[{"product":"advance_steel","vendor":"autodesk"},{"product":"autocad","vendor":"autodesk"},{"product":"autocad_architecture","vendor":"autodesk"},{"product":"autocad_electrical","vendor":"autodesk"},{"product":"autocad_lt","vendor":"autodesk"},{"product":"autocad_map_3d","vendor":"autodesk"},{"product":"autocad_mechanical","vendor":"autodesk"},{"product":"autocad_mep","vendor":"autodesk"},{"product":"autocad_plant_3d","vendor":"autodesk"},{"product":"civil_3d","vendor":"autodesk"},{"product":"inventor","vendor":"autodesk"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","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-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"An Information Disclosure vulnerability for JT files in Autodesk Inventor 2022, 2021, 2020, 2019 in conjunction with other vulnerabilities may lead to code execution through maliciously crafted JT files in the context of the current process.","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":"Information disclosure in Inventor","id":"CVE-2021-40159","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"autodesk:advance_steel","products":["autodesk:advance_steel","autodesk:autocad","autodesk:autocad_architecture","autodesk:autocad_electrical","autodesk:autocad_lt","autodesk:autocad_map_3d","autodesk:autocad_mechanical","autodesk:autocad_mep","autodesk:autocad_plant_3d","autodesk:civil_3d"],"type":"information_disclosure","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in Revit, Navisworks, Autodesk® Advance Steel, AutoCAD®, AutoCAD® Architecture, AutoCAD® Electrical, AutoCAD® Map 3D, AutoCAD® Mechanical, AutoCAD® MEP, AutoCAD® Plant 3D, AutoCAD® LT, Autodesk® Civil 3D, AutoCAD® Mac, AutoCAD® LT for Mac","id":"CVE-2021-40160"},"packages":[],"prev":{"headline":"Memory corruption in Inventor","id":"CVE-2021-40158"},"products":["Inventor"],"published":"2022-01-25","related":[{"cvss_score":7.8,"headline":"BMP File Parsing Untrusted Pointer Dereference in certain Autodesk products","id":"CVE-2026-7406","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":7.8,"headline":"DXF File Parsing Heap-Based Overflow in Autodesk AutoCAD","id":"CVE-2026-16463","kev_date_added":null,"published":"2026-07-29"},{"cvss_score":7.8,"headline":"PDF File Parsing Out-of-Bounds Write Vulnerability","id":"CVE-2025-8893","kev_date_added":null,"published":"2025-09-16"},{"cvss_score":7.8,"headline":"PDF File Parsing Heap-Based Buffer Overflow Vulnerability","id":"CVE-2025-8894","kev_date_added":null,"published":"2025-09-16"},{"cvss_score":7.8,"headline":"DGN File Parsing Out-of-Bounds Read Vulnerability","id":"CVE-2025-5046","kev_date_added":null,"published":"2025-08-15"},{"cvss_score":7.8,"headline":"DGN File Parsing Uninitialized Variable Vulnerability","id":"CVE-2025-5047","kev_date_added":null,"published":"2025-08-15"},{"cvss_score":7.8,"headline":"DGN File Parsing Memory Corruption Vulnerability","id":"CVE-2025-5048","kev_date_added":null,"published":"2025-08-15"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-08","vendors":["n/a"]},"summary":"Attackers can exploit information disclosure in JT files to potentially achieve code execution in Autodesk Inventor.","url":"https://insights.sbomify.com/CVE-2021-40159/"}
