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-2021-21565 in the wild and no public exploit code.\n\nAffected product: Dell Powerscale Onefs. 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-2021-21565/ (Markdown: https://insights.sbomify.com/CVE-2021-21565/index.md)","id":"CVE-2021-21565","markdown":"https://insights.sbomify.com/CVE-2021-21565/index.md","name":"CVE-2021-21565","record":{"aliases":["GHSA-xxr9-34qv-3673"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Dell PowerScale OneFS","requires_auth":"none","summary":"An attacker can trigger a loop in SmartConnect causing high CPU usage and preventing DNS responses, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"dell","cpe":[{"product":"powerscale_onefs","vendor":"dell"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-834","name":"Excessive Iteration"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Dell PowerScale OneFS versions 9.1.0.3 and earlier contain a denial of service vulnerability.
