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-2023-28907 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-2023-28907/ (Markdown: https://insights.sbomify.com/CVE-2023-28907/index.md)","id":"CVE-2023-28907","markdown":"https://insights.sbomify.com/CVE-2023-28907/index.md","name":"CVE-2023-28907","record":{"aliases":["GHSA-5jg2-cjvx-wcpp"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"MIB3 infotainment system","requires_auth":"high_privilege","summary":"Attackers with main OS access can compromise the CAN processing core due to lack of memory isolation in MIB3 infotainment systems.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ASRG","cpe":[],"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-284","name":"Improper Access Control"}],"description":"There is no memory isolation between CPU cores of the MIB3 infotainment.
