Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-5353 in the wild and no public exploit code.\n\nAffected product: Dell Emc 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-2020-5353/ (Markdown: https://insights.sbomify.com/CVE-2020-5353/index.md)","id":"CVE-2020-5353","markdown":"https://insights.sbomify.com/CVE-2020-5353/index.md","name":"CVE-2020-5353","record":{"aliases":["GHSA-54h3-rfwf-3g76"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Dell Isilon OneFS","requires_auth":"low_privilege","summary":"An attacker can spoof a UID over NFS to rewrite sensitive files in the admin home directory, gaining administrative access to the system.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"dell","cpe":[{"product":"emc_isilon_onefs","vendor":"dell"},{"product":"emc_powerscale_onefs","vendor":"dell"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"The Dell Isilon OneFS versions 8.2.2 and earlier and Dell EMC PowerScale OneFS version 9.0.0 default configuration for Network File System (NFS) allows access to an 'admin' home directory.
