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-2023-5342 in the wild and no public exploit code.\n\nAffected product: Red Hat Enterprise Linux 10. 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-2023-5342/ (Markdown: https://insights.sbomify.com/CVE-2023-5342/index.md)","id":"CVE-2023-5342","markdown":"https://insights.sbomify.com/CVE-2023-5342/index.md","name":"CVE-2023-5342","record":{"aliases":["GHSA-pj5r-f4h5-qprv"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux Secure Boot","requires_auth":"high_privilege","summary":"An expired Secure Boot certificate in Fedora's shim allows loading of old or invalid signed boot components, bypassing security checks.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fedora","cpe":[],"cvss":{"score":4.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-324","name":"Use of a Key Past its Expiration Date"}],"description":"The Fedora Secure Boot CA certificate shipped with shim in Fedora was expired which could lead to old or invalid signed boot components being loaded.","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":"Shim: expired secure boot certificate","id":"CVE-2023-5342","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"Popup Box \u003c 3.7.9 - Admin+ Stored XSS","id":"CVE-2023-5343"},"packages":[],"prev":{"headline":"Imagemagick: heap use-after-free in coders/bmp.c","id":"CVE-2023-5341"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9"],"published":"2025-08-15","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":"2025-08-15","vendors":["Red Hat"]},"summary":"An expired Secure Boot certificate in Fedora's shim allows loading of old or invalid signed boot components, bypassing security checks.","url":"https://insights.sbomify.com/CVE-2023-5342/"}
