LeviStudio HMI Editor, published on 26 Apr 2018. 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-2018-7527 in the wild and no public exploit code.\n\nAffected product: WECON Technology Co., Ltd. LeviStudio HMI Editor. 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-2018-7527/ (Markdown: https://insights.sbomify.com/CVE-2018-7527/index.md)","id":"CVE-2018-7527","markdown":"https://insights.sbomify.com/CVE-2018-7527/index.md","name":"CVE-2018-7527","record":{"aliases":["GHSA-4r6c-hgqq-rr35"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"HMI programming software","requires_auth":"none","summary":"Attackers can execute arbitrary code by tricking users into opening a specially crafted file in Wecon HMI programming tools.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"levistudio_hmi_editor","vendor":"we-con"},{"product":"levistudiou","vendor":"we-con"},{"product":"pi_studio_hmi_project_programmer","vendor":"we-con"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A buffer overflow can be triggered in LeviStudio HMI Editor, Version 1.10 part of Wecon LeviStudioU 1.8.29, and PI Studio HMI Project Programmer, Build: November 11, 2017 and prior by opening a specially crafted file.","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":"Memory corruption in LeviStudio HMI Editor","id":"CVE-2018-7527","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"SQL injection in Geutebr\u0026#195;\u0026#188;ck G-Cam/EFD-2250 (part n\u0026#194;\u0026#176; 5.02024) firmware and Topline TopFD-2125 (part n\u0026#194;\u0026#176; 5.02820) firmware","id":"CVE-2018-7528"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2018-7526"},"products":["LeviStudio HMI Editor","PI Studio HMI Project Programmer"],"published":"2018-04-26","related":[],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["WECON Technology Co., Ltd."]},"summary":"Attackers can execute arbitrary code by tricking users into opening a specially crafted file in Wecon HMI programming tools.","url":"https://insights.sbomify.com/CVE-2018-7527/"}
