It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-8834 in the wild and no public exploit code.\n\nAffected product: ICS-CERT 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-2018-8834/ (Markdown: https://insights.sbomify.com/CVE-2018-8834/index.md)","id":"CVE-2018-8834","markdown":"https://insights.sbomify.com/CVE-2018-8834/index.md","name":"CVE-2018-8834","record":{"aliases":["GHSA-qm7h-hvgh-53wq"],"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":"low_privilege","summary":"Heap-based buffer overflow in Omron CX-One allows code execution via malformed project files, impacting industrial control system users.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"cx-flnet","vendor":"omron"},{"product":"cx-one","vendor":"omron"},{"product":"cx-programmer","vendor":"omron"},{"product":"cx-protocol","vendor":"omron"},{"product":"cx-server","vendor":"omron"},{"product":"network_configurator","vendor":"omron"},{"product":"switch_box_utility","vendor":"omron"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"Parsing malformed project files in Omron CX-One versions 4.42 and prior, including the following applications: CX-FLnet versions 1.00 and prior, CX-Protocol versions 1.992 and prior, CX-Programmer versions 9.65 and prior, CX-Server versions 5.0.22 and prior, Network Configurator versions 3.63 and prior, and Switch Box Utility versions 1.68 and prior, may cause a heap-based buffer overflow.","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 Omron CX-One","id":"CVE-2018-8834","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Use after free in Advantech WebAccess HMI Designer","id":"CVE-2018-8835"},"packages":[],"prev":{"headline":"Memory corruption in Advantech WebAccess HMI Designer","id":"CVE-2018-8833"},"products":["Omron CX-One"],"published":"2018-04-17","related":[{"cvss_score":7.8,"headline":"Memory corruption in Omron CX-One","id":"CVE-2018-7514","kev_date_added":null,"published":"2018-04-17"},{"cvss_score":7.8,"headline":"Memory corruption in Omron CX-One","id":"CVE-2018-7530","kev_date_added":null,"published":"2018-04-17"}],"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":["ICS-CERT"]},"summary":"Heap-based buffer overflow in Omron CX-One allows code execution via malformed project files, impacting industrial control system users.","url":"https://insights.sbomify.com/CVE-2018-8834/"}
