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-2021-38409 and fix it if it is affected.\n\nWhat it is: CVE-2021-38409 is a high-severity vulnerability in Fuji Electric Tellus Lite V-Simulator, published on 20 Dec 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-2021-38409 in the wild and no public exploit code.\n\nAffected product: Fuji Electric Tellus Lite V-Simulator. 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-2021-38409/ (Markdown: https://insights.sbomify.com/CVE-2021-38409/index.md)","id":"CVE-2021-38409","markdown":"https://insights.sbomify.com/CVE-2021-38409/index.md","name":"CVE-2021-38409","record":{"aliases":["GHSA-fj3g-r3pf-r284"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"SCADA simulator software","requires_auth":"none","summary":"An attacker can cause a denial of service in Fuji Electric Tellus Lite V-Simulator by exploiting an uninitialized pointer vulnerability.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"v-server","vendor":"fujielectric"},{"product":"v-simulator","vendor":"fujielectric"}],"cvss":{"score":7.8,"severity":"high","source":"cna","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-824","name":"Access of Uninitialized Pointer"}],"description":"Fuji Electric V-Server Lite and Tellus Lite V-Simulator prior to v4.0.12.0 is vulnerable to an access of uninitialized pointer, which may allow an attacker read from or write to unexpected memory locations, leading to a denial-of-service.","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":"Fuji Electric Tellus Lite V-Simulator uninitialized pointer","id":"CVE-2021-38409","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"AVEVA PCS Portal Uncontrolled Search Path Element","id":"CVE-2021-38410"},"packages":[],"prev":{"headline":"Memory corruption in Advantech WebAccess","id":"CVE-2021-38408"},"products":["Tellus Lite V-Simulator","V-Server Lite"],"published":"2021-12-20","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 and V-Server Lite","id":"CVE-2023-31239","kev_date_added":null,"published":"2023-06-19"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Fuji Electric"]},"summary":"An attacker can cause a denial of service in Fuji Electric Tellus Lite V-Simulator by exploiting an uninitialized pointer vulnerability.","url":"https://insights.sbomify.com/CVE-2021-38409/"}
