Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-66598 in the wild and no public exploit code.\n\nAffected product: Yokogawa Electric Corporation FAST/TOOLS. 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-2025-66598/ (Markdown: https://insights.sbomify.com/CVE-2025-66598/index.md)","id":"CVE-2025-66598","markdown":"https://insights.sbomify.com/CVE-2025-66598/index.md","name":"CVE-2025-66598","record":{"aliases":["GHSA-vwj8-79vf-v875"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Yokogawa FAST/TOOLS","requires_auth":"low_privilege","summary":"An attacker can decrypt communications with the web server due to support for old SSL/TLS versions in Yokogawa FAST/TOOLS.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"YokogawaGroup","cpe":[{"product":"fast\\/tools","vendor":"yokogawa"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"A vulnerability has been found in FAST/TOOLS provided by Yokogawa Electric Corporation.\n\nThis product supports\nold SSL/TLS versions, potentially allowing an attacker to decrypt\ncommunications with the web server.\n\nThe\naffected products and versions are as follows: FAST/TOOLS (Packages: RVSVRN, UNSVRN, HMIWEB, FTEES, HMIMOB) R9.01 to\nR10.04","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":"Weak cryptography in FAST/TOOLS","id":"CVE-2025-66598","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in FAST/TOOLS","id":"CVE-2025-66599"},"packages":[],"prev":{"headline":"Weak cryptography in FAST/TOOLS","id":"CVE-2025-66597"},"products":["FAST/TOOLS"],"published":"2026-02-09","related":[{"cvss_score":8.8,"headline":"Weak cryptography in FAST/TOOLS","id":"CVE-2025-66597","kev_date_added":null,"published":"2026-02-09"},{"cvss_score":8.7,"headline":"Path traversal in FAST/TOOLS","id":"CVE-2025-66608","kev_date_added":null,"published":"2026-02-09"},{"cvss_score":6.9,"headline":"Information disclosure in FAST/TOOLS","id":"CVE-2025-66594","kev_date_added":null,"published":"2026-02-09"},{"cvss_score":6.9,"headline":"Open redirect in FAST/TOOLS","id":"CVE-2025-66596","kev_date_added":null,"published":"2026-02-09"},{"cvss_score":6.9,"headline":"Missing authorization in FAST/TOOLS","id":"CVE-2025-66602","kev_date_added":null,"published":"2026-02-09"},{"cvss_score":6.3,"headline":"Cross-site request forgery in FAST/TOOLS","id":"CVE-2025-66595","kev_date_added":null,"published":"2026-02-09"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-02-09","vendors":["Yokogawa Electric Corporation"]},"summary":"An attacker can decrypt communications with the web server due to support for old SSL/TLS versions in Yokogawa FAST/TOOLS.","url":"https://insights.sbomify.com/CVE-2025-66598/"}
