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-2020-27257 and fix it if it is affected.\n\nWhat it is: CVE-2020-27257 is a high-severity memory corruption vulnerability in Omron CX-One, published on 9 Feb 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-2020-27257 in the wild and no public exploit code.\n\nAffected product: Omron CX-One. 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-2020-27257/ (Markdown: https://insights.sbomify.com/CVE-2020-27257/index.md)","id":"CVE-2020-27257","markdown":"https://insights.sbomify.com/CVE-2020-27257/index.md","name":"CVE-2020-27257","record":{"aliases":["GHSA-j58q-jg6x-x4h9"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Omron CX-One","requires_auth":"none","summary":"Local attackers can execute arbitrary code via type confusion in Omron CX-One industrial control software.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"cx-one","vendor":"omron"},{"product":"cx-position","vendor":"omron"},{"product":"cx-protocol","vendor":"omron"},{"product":"cx-server","vendor":"omron"}],"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-843","name":"Access of Resource Using Incompatible Type"}],"description":"This vulnerability allows local attackers to execute arbitrary code due to the lack of proper validation of user-supplied data, which can result in a type-confusion condition in the Omron CX-One Version 4.60 and prior devices.","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":"Omron CX-One","id":"CVE-2020-27257","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in SOOIL Developments Co., Ltd Diabecare RS, AnyDana-i and AnyDana-A","id":"CVE-2020-27258"},"packages":[],"prev":{"headline":"Hardcoded credentials in SOOIL Developments Co., Ltd Diabecare RS, AnyDana-i and AnyDana-A","id":"CVE-2020-27256"},"products":["CX-One","CX-Position","CX-Protocol","CX-Server"],"published":"2021-02-09","related":[{"cvss_score":8.8,"headline":"Omron CX-One","id":"CVE-2020-27259","kev_date_added":null,"published":"2021-02-09"},{"cvss_score":8.8,"headline":"Omron CX-One","id":"CVE-2020-27261","kev_date_added":null,"published":"2021-02-09"},{"cvss_score":7.8,"headline":"Omron CX-One","id":"CVE-2022-21137","kev_date_added":null,"published":"2022-01-14"},{"cvss_score":7.8,"headline":"Memory corruption in Omron CX-One","id":"CVE-2021-27413","kev_date_added":null,"published":"2021-05-13"},{"cvss_score":7.8,"headline":"Memory corruption in CX-Protocol within CX-One","id":"CVE-2018-19027","kev_date_added":null,"published":"2019-01-30"},{"cvss_score":7.8,"headline":"Use after free in CX-One (CX-Programmer and CX-Server)","id":"CVE-2018-18989","kev_date_added":null,"published":"2018-12-04"}],"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":"2024-09-17","vendors":["Omron"]},"summary":"Local attackers can execute arbitrary code via type confusion in Omron CX-One industrial control software.","url":"https://insights.sbomify.com/CVE-2020-27257/"}
