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-2020-5609 in the wild and no public exploit code.\n\nAffected product: Yokogawa Electric Corporation CAMS for HIS. 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-2020-5609/ (Markdown: https://insights.sbomify.com/CVE-2020-5609/index.md)","id":"CVE-2020-5609","markdown":"https://insights.sbomify.com/CVE-2020-5609/index.md","name":"CVE-2020-5609","record":{"aliases":["GHSA-5463-xg53-cjvw"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Yokogawa CAMS for HIS","requires_auth":"none","summary":"Remote unauthenticated attackers can exploit a directory traversal flaw in Yokogawa CAMS for HIS to create or overwrite files and execute arbitrary commands.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"b\\/m9000cs_firmware","vendor":"yokogawa"},{"product":"b\\/m9000vp_firmware","vendor":"yokogawa"},{"product":"centum_cs_3000_firmware","vendor":"yokogawa"},{"product":"centum_vp_firmware","vendor":"yokogawa"}],"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-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Directory traversal vulnerability in CAMS for HIS CENTUM CS 3000 (includes CENTUM CS 3000 Small) R3.08.10 to R3.09.50, CENTUM VP (includes CENTUM VP Small, Basic) R4.01.00 to R6.07.00, B/M9000CS R5.04.01 to R5.05.01, and B/M9000 VP R6.01.01 to R8.03.01 allows a remote unauthenticated attacker to create or overwrite arbitrary files and run arbitrary commands via unspecified vectors.","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":"Path traversal in CAMS for HIS","id":"CVE-2020-5609","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in Global TechStream (GTS) for TOYOTA dealers","id":"CVE-2020-5610"},"packages":[],"prev":{"headline":"Auth bypass in CAMS for HIS","id":"CVE-2020-5608"},"products":["CAMS for HIS"],"published":"2020-08-05","related":[{"cvss_score":9.8,"headline":"Auth bypass in CAMS for HIS","id":"CVE-2020-5608","kev_date_added":null,"published":"2020-08-05"}],"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":["Yokogawa Electric Corporation"]},"summary":"Remote unauthenticated attackers can exploit a directory traversal flaw in Yokogawa CAMS for HIS to create or overwrite files and execute arbitrary commands.","url":"https://insights.sbomify.com/CVE-2020-5609/"}
