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-2024-21781 in the wild and no public exploit code.\n\nAffected product: UEFI firmware for some Intel(R) Processors. 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-2024-21781/ (Markdown: https://insights.sbomify.com/CVE-2024-21781/index.md)","id":"CVE-2024-21781","markdown":"https://insights.sbomify.com/CVE-2024-21781/index.md","name":"CVE-2024-21781","record":{"aliases":["GHSA-pcx7-83rx-78c2"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Intel UEFI firmware","requires_auth":"high_privilege","summary":"A privileged local attacker can exploit improper input validation in Intel UEFI firmware to disclose information or cause denial of service.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"intel","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:H/UI:N/VC:H/VI:N/VA:H/SC:H/SI:N/SA:H","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper input validation in UEFI firmware for some Intel(R) Processors may allow a privileged user to enable information disclosure or denial of service via local access.","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":"Information disclosure in UEFI firmware for some Intel(R) Processors","id":"CVE-2024-21781","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"BIG-IP and BIG-IQ secure copy vulnerability","id":"CVE-2024-21782"},"packages":[],"prev":{"headline":"Memory corruption in HOME SPOT CUBE2","id":"CVE-2024-21780"},"products":["UEFI firmware for some Intel(R) Processors"],"published":"2024-09-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-03","vendors":["n/a"]},"summary":"A privileged local attacker can exploit improper input validation in Intel UEFI firmware to disclose information or cause denial of service.","url":"https://insights.sbomify.com/CVE-2024-21781/"}
