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-2022-26034 in the wild and no public exploit code.\n\nAffected product: Yokogawa Electric Corporation CENTUM VP series with VP6E5000(AD Suite Engineering ServerFunction) installed and B/M9000 VP. 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-2022-26034/ (Markdown: https://insights.sbomify.com/CVE-2022-26034/index.md)","id":"CVE-2022-26034","markdown":"https://insights.sbomify.com/CVE-2022-26034/index.md","name":"CVE-2022-26034","record":{"aliases":["GHSA-6r8v-ww3c-grvh"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Yokogawa CENTUM VP","requires_auth":"none","summary":"An attacker can bypass authentication in the AD server communication protocol to leak or tamper with managed data in Yokogawa CENTUM VP systems.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"b\\/m9000_vp","vendor":"yokogawa"},{"product":"centum_vp","vendor":"yokogawa"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Improper authentication vulnerability in the communication protocol provided by AD (Automation Design) server of CENTUM VP R6.01.10 to R6.09.00, CENTUM VP Small R6.01.10 to R6.09.00, CENTUM VP Basic R6.01.10 to R6.09.00, and B/M9000 VP R8.01.01 to R8.03.01 allows an attacker to use the functions provided by AD server.
