V-Server and V-Server Lite, published on 19 Jun 2023. 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-2023-31239 in the wild and no public exploit code.\n\nAffected product: FUJI ELECTRIC CO., LTD. and Hakko Electronics Co., Ltd. V-Server and V-Server Lite. 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-2023-31239/ (Markdown: https://insights.sbomify.com/CVE-2023-31239/index.md)","id":"CVE-2023-31239","markdown":"https://insights.sbomify.com/CVE-2023-31239/index.md","name":"CVE-2023-31239","record":{"aliases":["GHSA-hpj7-4fx3-hmfp"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"V-Server software","requires_auth":"none","summary":"Attackers can execute arbitrary code by tricking users into opening a specially crafted VPR file in V-Server software.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"v-server","vendor":"fujielectric"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","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-125","name":"Out-of-bounds Read"}],"description":"Stack-based buffer overflow vulnerability in V-Server v4.0.15.0 and V-Server Lite v4.0.15.0 and earlier allows an attacker to execute arbitrary code by having user open a specially crafted VPR 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 V-Server and V-Server Lite","id":"CVE-2023-31239","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Hardcoded credentials in OvrC Cloud","id":"CVE-2023-31240"},"packages":[],"prev":{"headline":"A vulnerability has been identified in SICAM P850 (7KG8500-0AA00-0AA0) (All versions \u003c V3.11), SICAM P850 (7KG8500-0AA00-2AA0) (All versions","id":"CVE-2023-31238"},"products":["V-Server and V-Server Lite"],"published":"2023-06-19","related":[{"cvss_score":9.8,"headline":"Memory corruption in Fuji Electric V-Server 4.0.6 and prior","id":"CVE-2019-18240","kev_date_added":null,"published":"2019-11-13"},{"cvss_score":9.8,"headline":"Hardcoded credentials in Fuji Electric V-Server","id":"CVE-2019-3947","kev_date_added":null,"published":"2019-06-12"},{"cvss_score":7.8,"headline":"Memory corruption in V-Server","id":"CVE-2023-47584","kev_date_added":null,"published":"2023-11-15"},{"cvss_score":7.8,"headline":"Memory corruption in V-Server","id":"CVE-2023-47585","kev_date_added":null,"published":"2023-11-15"},{"cvss_score":7.8,"headline":"Memory corruption in V-Server","id":"CVE-2023-47586","kev_date_added":null,"published":"2023-11-15"},{"cvss_score":7.8,"headline":"Memory corruption in V-Server","id":"CVE-2022-41645","kev_date_added":null,"published":"2023-01-03"}],"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":"2024-12-23","vendors":["FUJI ELECTRIC CO., LTD. and Hakko Electronics Co., Ltd."]},"summary":"Attackers can execute arbitrary code by tricking users into opening a specially crafted VPR file in V-Server software.","url":"https://insights.sbomify.com/CVE-2023-31239/"}
