It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-27097 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-2021-27097/ (Markdown: https://insights.sbomify.com/CVE-2021-27097/index.md)","id":"CVE-2021-27097","markdown":"https://insights.sbomify.com/CVE-2021-27097/index.md","name":"CVE-2021-27097","record":{"aliases":["ALPINE-CVE-2021-27097","DEBIAN-CVE-2021-27097","GHSA-3w66-96j7-fmcp","UBUNTU-CVE-2021-27097"],"analysis":{"component_type":"hardware_firmware","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"U-Boot bootloader","requires_auth":"none","summary":"Attackers can execute arbitrary code by providing a modified FIT image to the U-Boot bootloader, compromising the device's boot process.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"u-boot","vendor":"denx"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AC:L/AV:L/A:H/C:H/I:H/PR:N/S:U/UI:R","version":"3.1"},"cwes":[],"description":"The boot loader in Das U-Boot before 2021.04-rc2 mishandles a modified FIT.","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":"Code injection in n/a","id":"CVE-2021-27097","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Legacy Node API Allows Impersonation in github.com/spiffe/spire/pkg/server/endpoints/node","id":"CVE-2021-27098"},"packages":[],"prev":{"headline":"NTFS Elevation of Privilege Vulnerability","id":"CVE-2021-27096"},"products":["n/a"],"published":"2021-02-17","related":[{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2022-34835","kev_date_added":null,"published":"2022-06-29"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-30767","kev_date_added":null,"published":"2022-05-16"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-8432","kev_date_added":null,"published":"2020-01-29"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2019-14192","kev_date_added":null,"published":"2019-07-31"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-14193","kev_date_added":null,"published":"2019-07-31"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-14194","kev_date_added":null,"published":"2019-07-31"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-14195","kev_date_added":null,"published":"2019-07-31"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2025-11-03","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code by providing a modified FIT image to the U-Boot bootloader, compromising the device's boot process.","url":"https://insights.sbomify.com/CVE-2021-27097/"}
