It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-28904 exists.\n\nAffected product: Preh Car Connect GmbH (JOYNEXT GmbH) Volkswagen MIB3 infotainment system MIB3 OI MQB. 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-2023-28904/ (Markdown: https://insights.sbomify.com/CVE-2023-28904/index.md)","id":"CVE-2023-28904","markdown":"https://insights.sbomify.com/CVE-2023-28904/index.md","name":"CVE-2023-28904","record":{"aliases":["GHSA-gqwg-33mc-9c6j"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Volkswagen infotainment system","requires_auth":"none","summary":"Physical access allows bypassing secure boot via buffer overflow, enabling arbitrary code execution on the infotainment system.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ASRG","cpe":[],"cvss":{"score":5.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A logic flaw leading to a RAM buffer overflow in the bootloader component of the MIB3 infotainment unit allows an attacker with physical access to the MIB3 ECU to bypass firmware signature verification and run arbitrary code in the infotainment system at boot process.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Bypass of secure boot process","id":"CVE-2023-28904","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"Heap buffer overflow in picserver","id":"CVE-2023-28905"},"packages":[],"prev":{"headline":"Integer overflow in Volkswagen MIB3 infotainment system MIB3 OI MQB","id":"CVE-2023-28903"},"products":["Volkswagen MIB3 infotainment system MIB3 OI MQB"],"published":"2025-06-28","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-06-30","vendors":["Preh Car Connect GmbH (JOYNEXT GmbH)"]},"summary":"Physical access allows bypassing secure boot via buffer overflow, enabling arbitrary code execution on the infotainment system.","url":"https://insights.sbomify.com/CVE-2023-28904/"}
