It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-28210 in the wild and no public exploit code.\n\nAffected product: TianoCore EDK II. 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-2021-28210/ (Markdown: https://insights.sbomify.com/CVE-2021-28210/index.md)","id":"CVE-2021-28210","markdown":"https://insights.sbomify.com/CVE-2021-28210/index.md","name":"CVE-2021-28210","record":{"aliases":["DEBIAN-CVE-2021-28210","GHSA-3q28-wqh2-j2f3","OESA-2021-1251","UBUNTU-CVE-2021-28210"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"UEFI firmware","requires_auth":"low_privilege","summary":"An attacker can cause a denial of service in EDK II UEFI firmware via unlimited recursion in DxeCore.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TianoCore","cpe":[{"product":"edk2","vendor":"tianocore"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"}],"description":"An unlimited recursion in DxeCore in EDK II.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service in EDK II","id":"CVE-2021-28210","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in EDK II","id":"CVE-2021-28211"},"packages":[],"prev":{"headline":"ASUS BMC's firmware: path traversal - Delete video file function","id":"CVE-2021-28209"},"products":["EDK II"],"published":"2021-06-11","related":[{"cvss_score":8.3,"headline":"Buffer Overflow in EDK II Network Package","id":"CVE-2023-45230","kev_date_added":null,"published":"2024-01-16"},{"cvss_score":8.3,"headline":"Buffer Overflow in EDK II Network Package","id":"CVE-2023-45234","kev_date_added":null,"published":"2024-01-16"},{"cvss_score":8.3,"headline":"Buffer Overflow in EDK II Network Package","id":"CVE-2023-45235","kev_date_added":null,"published":"2024-01-16"},{"cvss_score":7.8,"headline":"Null dereference in Tianocore EDK2","id":"CVE-2019-14584","kev_date_added":null,"published":"2021-06-03"},{"cvss_score":7.8,"headline":"Privilege escalation in Tianocore","id":"CVE-2017-5731","kev_date_added":null,"published":"2019-10-28"},{"cvss_score":7.5,"headline":"Infinite loop in EDK II Network Package","id":"CVE-2023-45232","kev_date_added":null,"published":"2024-01-16"}],"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":"2024-08-03","vendors":["TianoCore"]},"summary":"An attacker can cause a denial of service in EDK II UEFI firmware via unlimited recursion in DxeCore.","url":"https://insights.sbomify.com/CVE-2021-28210/"}
