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-2021-38436 and fix it if it is affected.\n\nWhat it is: CVE-2021-38436 is a high-severity memory corruption vulnerability in FATEK Automation WinProladder, published on 18 Oct 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-2021-38436 in the wild and no public exploit code.\n\nAffected product: FATEK Automation WinProladder. 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-2021-38436/ (Markdown: https://insights.sbomify.com/CVE-2021-38436/index.md)","id":"CVE-2021-38436","markdown":"https://insights.sbomify.com/CVE-2021-38436/index.md","name":"CVE-2021-38436","record":{"aliases":["GHSA-8wh7-53ff-95r7"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ICS programming software","requires_auth":"none","summary":"An attacker can execute arbitrary code by tricking a user into opening a malicious project file in FATEK WinProladder.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"winproladder","vendor":"fatek"}],"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-787","name":"Out-of-bounds Write"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"FATEK Automation WinProladder versions 3.30 and prior lacks proper validation of user-supplied data when parsing project files, which could result in a memory-corruption condition.
