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-2020-16243 and fix it if it is affected.\n\nWhat it is: CVE-2020-16243 is a high-severity memory corruption vulnerability in LeviStudioU, published on 23 Feb 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-2020-16243 in the wild and no public exploit code.\n\nAffected product: LeviStudioU. 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-2020-16243/ (Markdown: https://insights.sbomify.com/CVE-2020-16243/index.md)","id":"CVE-2020-16243","markdown":"https://insights.sbomify.com/CVE-2020-16243/index.md","name":"CVE-2020-16243","record":{"aliases":["GHSA-fj3m-f5px-cp9p"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PLC programming software","requires_auth":"none","summary":"Attackers can execute arbitrary code by tricking users into opening malicious project files in LeviStudioU, posing a risk to industrial control system operators.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"levistudiou","vendor":"we-con"}],"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-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Multiple buffer overflow vulnerabilities exist when LeviStudioU (Version 2019-09-21 and prior) processes project files.
