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-2020-28940 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-28940/ (Markdown: https://insights.sbomify.com/CVE-2020-28940/index.md)","id":"CVE-2020-28940","markdown":"https://insights.sbomify.com/CVE-2020-28940/index.md","name":"CVE-2020-28940","record":{"aliases":["GHSA-wrfx-v3mv-pvww"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Western Digital NAS","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication on Western Digital My Cloud OS 5 NAS devices to execute privileged commands.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"my_cloud_os_5","vendor":"westerndigital"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"On Western Digital My Cloud OS 5 devices before 5.06.115, the NAS Admin dashboard has an authentication bypass vulnerability that could allow an unauthenticated user to execute privileged commands on the device.","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":"Auth bypass in n/a","id":"CVE-2020-28940","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Use after free in n/a","id":"CVE-2020-28941"},"packages":[],"prev":{"headline":"File upload in n/a","id":"CVE-2020-28939"},"products":["n/a"],"published":"2020-12-01","related":[{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2020-29563","kev_date_added":null,"published":"2020-12-11"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2020-28970","kev_date_added":null,"published":"2020-12-01"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2020-28971","kev_date_added":null,"published":"2020-12-01"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Unauthenticated attackers can bypass authentication on Western Digital My Cloud OS 5 NAS devices to execute privileged commands.","url":"https://insights.sbomify.com/CVE-2020-28940/"}
