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-2020-14372 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2020-14372/ (Markdown: https://insights.sbomify.com/CVE-2020-14372/index.md)","id":"CVE-2020-14372","markdown":"https://insights.sbomify.com/CVE-2020-14372/index.md","name":"CVE-2020-14372","record":{"aliases":["ALPINE-CVE-2020-14372","AZL-6460","DEBIAN-CVE-2020-14372","GHSA-xh73-rjw5-phcw","UBUNTU-CVE-2020-14372"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GRUB2 bootloader","requires_auth":"high_privilege","summary":"An attacker with privileged access can bypass Secure Boot lockdown via crafted ACPI tables to load unsigned code, compromising system integrity.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"grub2","vendor":"gnu"},{"product":"cloud_backup","vendor":"netapp"},{"product":"ontap_select_deploy_administration_utility","vendor":"netapp"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"enterprise_linux_server_aus","vendor":"redhat"},{"product":"enterprise_linux_server_eus","vendor":"redhat"},{"product":"enterprise_linux_server_tus","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-184","name":"Incomplete List of Disallowed Inputs"}],"description":"A flaw was found in grub2 in versions prior to 2.06, where it incorrectly enables the usage of the ACPI command when Secure Boot is enabled. This flaw allows an attacker with privileged access to craft a Secondary System Description Table (SSDT) containing code to overwrite the Linux kernel lockdown variable content directly into memory. The table is further loaded and executed by the kernel, defeating its Secure Boot lockdown and allowing the attacker to load unsigned code. The highest threat from this vulnerability is to data confidentiality and integrity, as well as system availability.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2021-04-19","github_poc":1,"max_poc_stars":4,"metasploit":0,"nuclei":0,"refs":[{"date":"2021-04-19T23:36:25Z","kind":"github_poc","ref":"https://github.com/kukrimate/CVE-2020-14372","stars":4,"title":"Write-up and proof of concept exploit for CVE-2020-14372"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Security feature bypass in grub2","id":"CVE-2020-14372","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fedoraproject:fedora","products":["fedoraproject:fedora","netapp:cloud_backup","netapp:ontap_select_deploy_administration_utility","redhat:enterprise_linux","redhat:enterprise_linux_server_aus","redhat:enterprise_linux_server_eus","redhat:enterprise_linux_server_tus","redhat:enterprise_linux_workstation"],"type":"security_feature_bypass","year":"2020"},"n_packages":0,"n_references":5,"next":{"headline":"Use after free in ghostscript","id":"CVE-2020-14373"},"packages":[],"prev":{"headline":"Information disclosure in Red Hat Satellite","id":"CVE-2020-14371"},"products":["grub2"],"published":"2021-03-03","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"An attacker with privileged access can bypass Secure Boot lockdown via crafted ACPI tables to load unsigned code, compromising system integrity.","url":"https://insights.sbomify.com/CVE-2020-14372/"}
