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-2021-40334 in the wild and no public exploit code.\n\nAffected product: Hitachi Energy FOX61x. 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-2021-40334/ (Markdown: https://insights.sbomify.com/CVE-2021-40334/index.md)","id":"CVE-2021-40334","markdown":"https://insights.sbomify.com/CVE-2021-40334/index.md","name":"CVE-2021-40334","record":{"aliases":["GHSA-4cmw-rq6h-3v7m"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Hitachi Energy network device","requires_auth":"none","summary":"An attacker can disrupt network management communication by exploiting a missing handler in the proprietary management protocol on Hitachi Energy devices.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Hitachi Energy","cpe":[{"product":"fox615_firmware","vendor":"hitachienergy"},{"product":"xcm20_firmware","vendor":"hitachienergy"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-431","name":"Missing Handler"}],"description":"Missing Handler vulnerability in the proprietary management protocol (port TCP 5558) of Hitachi Energy FOX61x, XCM20 allows an attacker that exploits the vulnerability by activating SSH on port TCP 5558 to cause disruption to the NMS and NE communication.
