An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-18259 in the wild and no public exploit code.\n\nAffected product: Omron PLC CJ and CS Series. 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-2019-18259/ (Markdown: https://insights.sbomify.com/CVE-2019-18259/index.md)","id":"CVE-2019-18259","markdown":"https://insights.sbomify.com/CVE-2019-18259/index.md","name":"CVE-2019-18259","record":{"aliases":["GHSA-jwh5-53wq-83vf"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Omron PLC","requires_auth":"none","summary":"Attackers can spoof messages or execute commands on Omron PLC CJ and CS series devices, compromising industrial control operations.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"plc_cj_firmware","vendor":"omron"},{"product":"plc_cs_firmware","vendor":"omron"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"In Omron PLC CJ series, all versions and Omron PLC CS series, all versions, an attacker could spoof arbitrary messages or execute commands.","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":"Other in Omron PLC CJ and CS Series","id":"CVE-2019-18259","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in Omron PLC CJ, CS and NJ Series","id":"CVE-2019-18261"},"packages":[],"prev":{"headline":"Memory corruption in Advantech DiagAnywhere Server","id":"CVE-2019-18257"},"products":["Omron PLC CJ and CS Series"],"published":"2019-12-16","related":[{"cvss_score":9.8,"headline":"Auth bypass in Omron PLC CJ, CS and NJ Series","id":"CVE-2019-18261","kev_date_added":null,"published":"2019-12-16"},{"cvss_score":8.6,"headline":"Missing authorization in Omron PLC CJ Series","id":"CVE-2019-18269","kev_date_added":null,"published":"2019-12-16"},{"cvss_score":8.1,"headline":"Other in Omron PLC CJ and CS Series","id":"CVE-2019-13533","kev_date_added":null,"published":"2019-12-16"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can spoof messages or execute commands on Omron PLC CJ and CS series devices, compromising industrial control operations.","url":"https://insights.sbomify.com/CVE-2019-18259/"}
