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-2021-38406 and fix it if it is affected.\n\nWhat it is: CVE-2021-38406 is a high-severity memory corruption vulnerability in Delta Electronics DOPSoft 2, published on 17 Sep 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: Yes. Attackers have exploited CVE-2021-38406 in the wild since at least 25 Aug 2022.\n\nAffected product: Delta Electronics DOPSoft 2. 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-2021-38406/ (Markdown: https://insights.sbomify.com/CVE-2021-38406/index.md)","id":"CVE-2021-38406","markdown":"https://insights.sbomify.com/CVE-2021-38406/index.md","name":"CVE-2021-38406","record":{"aliases":["GHSA-j3xh-c39x-qghw"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"HMI configuration software","requires_auth":"none","summary":"An attacker can execute arbitrary code by tricking a user into opening a malicious project file in Delta Electronics DOPSoft 2.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"dopsoft","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-787","name":"Out-of-bounds Write"}],"description":"Delta Electronic DOPSoft 2 (Version 2.00.07 and prior) lacks proper validation of user-supplied data when parsing specific project files.
