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-2019-6539 in the wild and no public exploit code.\n\nAffected product: ICS-CERT WECON 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-2019-6539/ (Markdown: https://insights.sbomify.com/CVE-2019-6539/index.md)","id":"CVE-2019-6539","markdown":"https://insights.sbomify.com/CVE-2019-6539/index.md","name":"CVE-2019-6539","record":{"aliases":["GHSA-3qfx-cxcm-pc2c"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ICS HMI software","requires_auth":"none","summary":"Heap-based buffer overflows in WECON LeviStudioU allow attackers to execute arbitrary code via crafted inputs.","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-122","name":"Heap-based Buffer Overflow"}],"description":"Several heap-based buffer overflow vulnerabilities in WECON LeviStudioU version 1.8.56 and prior have been identified, which may allow arbitrary code execution.
