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-2024-38433 in the wild and no public exploit code.\n\nAffected product: Nuvoton NPCM7xx (Poleg) BootBlock. 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-2024-38433/ (Markdown: https://insights.sbomify.com/CVE-2024-38433/index.md)","id":"CVE-2024-38433","markdown":"https://insights.sbomify.com/CVE-2024-38433/index.md","name":"CVE-2024-38433","record":{"aliases":["GHSA-jx2p-c252-qcmr"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Nuvoton BMC firmware","requires_auth":"high_privilege","summary":"Attackers with SPI-Flash write access can modify u-boot headers to bypass authentication and execute arbitrary code on Nuvoton BMCs.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"INCD","cpe":[{"product":"npcm705r_firmware","vendor":"nuvoton"},{"product":"npcm710r_firmware","vendor":"nuvoton"},{"product":"npcm730r_firmware","vendor":"nuvoton"},{"product":"npcm750r_firmware","vendor":"nuvoton"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-305","name":"Authentication Bypass by Primary Weakness"}],"description":"Nuvoton - CWE-305: Authentication Bypass by Primary Weakness\n\nAn attacker with write access to the SPI-Flash on an NPCM7xx BMC subsystem that uses the Nuvoton BootBlock\n\nreference code can modify the u-boot image header on flash parsed by the BootBlock which could lead to arbitrary code\n\nexecution.","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":"Nuvoton - CWE-305: Authentication Bypass by Primary Weakness","id":"CVE-2024-38433","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Unitronics Vision PLC - CWE-676: Use of Potentially Dangerous Function","id":"CVE-2024-38434"},"packages":[],"prev":{"headline":"Matrix – Tafnit v8 CWE-646: Reliance on File Name or Extension of Externally-Supplied File","id":"CVE-2024-38432"},"products":["NPCM7xx (Poleg) BootBlock"],"published":"2024-07-11","related":[],"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)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-08-02","vendors":["Nuvoton"]},"summary":"Attackers with SPI-Flash write access can modify u-boot headers to bypass authentication and execute arbitrary code on Nuvoton BMCs.","url":"https://insights.sbomify.com/CVE-2024-38433/"}
