An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-40250 in the wild and no public exploit code.\n\nAffected product: Hancom HCell. 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-2023-40250/ (Markdown: https://insights.sbomify.com/CVE-2023-40250/index.md)","id":"CVE-2023-40250","markdown":"https://insights.sbomify.com/CVE-2023-40250/index.md","name":"CVE-2023-40250","record":{"aliases":["GHSA-mxwh-m8g8-q6j7"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Hancom HCell","requires_auth":"none","summary":"A buffer overflow in Hancom HCell on Windows allows attackers to execute arbitrary code or cause a denial of service.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"krcert","cpe":[{"product":"hcell","vendor":"hancom"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in Hancom HCell on Windows allows Overflow Buffers.This issue affects HCell: 12.0.0.893.","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 HCell","id":"CVE-2023-40250","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Weak cryptography in Genian NAC Suite V5.0","id":"CVE-2023-40251"},"packages":[],"prev":{"headline":"XML external entity in n/a","id":"CVE-2023-40239"},"products":["HCell"],"published":"2024-01-12","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-11-14","vendors":["Hancom"]},"summary":"A buffer overflow in Hancom HCell on Windows allows attackers to execute arbitrary code or cause a denial of service.","url":"https://insights.sbomify.com/CVE-2023-40250/"}
