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-2023-43634 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/lf-edge/eve (Go): affected all versions; fixed in 0.0.0-20230519072751-977f42b07fa9\n- github.com/lf-edge/eve (Go): affected all versions; fixed in 0.0.0-20230519072751-977f42b07fa9\n- github.com/lf-edge/eve (Go): affected all versions; fixed in 0.0.0-20230519072751-977f42b07fa9\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-2023-43634/ (Markdown: https://insights.sbomify.com/CVE-2023-43634/index.md)","id":"CVE-2023-43634","markdown":"https://insights.sbomify.com/CVE-2023-43634/index.md","name":"CVE-2023-43634","record":{"aliases":["GHSA-wc42-fcjp-v8vq","GO-2026-4432"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"EVE OS","requires_auth":"low_privilege","summary":"Attackers can modify the configuration partition without detection, gaining full device control and access to encrypted vault keys due to a measured boot bypass.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ASRG","cpe":[{"product":"eve","vendor":"lfedge"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-922","name":"Insecure Storage of Sensitive Information"},{"id":"CWE-522","name":"Insufficiently Protected Credentials"}],"description":"When sealing/unsealing the “vault” key, a list of PCRs is used, which defines which PCRs\nare used.\n\nIn a previous project, CYMOTIVE found that the configuration is not protected by the secure\nboot, and in response Zededa implemented measurements on the config partition that was\nmapped to PCR 13.\n\nIn that process, PCR 13 was added to the list of PCRs that seal/unseal the key.\n\nIn commit “56e589749c6ff58ded862d39535d43253b249acf”, the config partition\nmeasurement moved from PCR 13 to PCR 14, but PCR 14 was not added to the list of\nPCRs that seal/unseal the key.\n\nThis change makes the measurement of PCR 14 effectively redundant as it would not affect\nthe sealing/unsealing of the key.\n\nAn attacker could modify the config partition without triggering the measured boot, this could\nresult in the attacker gaining full control over the device with full access to the contents of the\nencrypted “vault”","ecosystems":["Go"],"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":"Config Partition Not Protected by Measured Boot","id":"CVE-2023-43634","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"security_feature_bypass","year":"2023"},"n_packages":3,"n_references":1,"next":{"headline":"Vault Key Sealed With SHA1 PCRs","id":"CVE-2023-43635"},"packages":[{"ecosystem":"Go","fixed":["0.0.0-20230519072751-977f42b07fa9"],"introduced":["0"],"last_affected":[],"package":"github.com/lf-edge/eve","purl":null,"source":"GHSA-wc42-fcjp-v8vq"},{"ecosystem":"Go","fixed":["0.0.0-20230519072751-977f42b07fa9"],"introduced":["0"],"last_affected":[],"package":"github.com/lf-edge/eve","purl":"pkg:golang/github.com/lf-edge/eve","source":"GHSA-wc42-fcjp-v8vq"},{"ecosystem":"Go","fixed":["0.0.0-20230519072751-977f42b07fa9"],"introduced":["0"],"last_affected":[],"package":"github.com/lf-edge/eve","purl":"pkg:golang/github.com/lf-edge/eve","source":"GO-2026-4432"}],"prev":{"headline":"Debug Functions Unlockable Without Triggering Measured Boot","id":"CVE-2023-43633"},"products":["EVE OS"],"published":"2023-09-21","related":[{"cvss_score":8.8,"headline":"Debug Functions Unlockable Without Triggering Measured Boot","id":"CVE-2023-43633","kev_date_added":null,"published":"2023-09-21"},{"cvss_score":7.8,"headline":"Vault Key Partially Predetermined","id":"CVE-2023-43637","kev_date_added":null,"published":"2023-09-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-09-24","vendors":[" LF-Edge, Zededa"]},"summary":"Attackers can modify the configuration partition without detection, gaining full device control and access to encrypted vault keys due to a measured boot bypass.","url":"https://insights.sbomify.com/CVE-2023-43634/"}
