CVE-2023-29113
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe MIB3 infotainment unit used in Skoda and Volkswagen vehicles does not incorporate any privilege separation for the proprietary inter-process communication mechanism, leaving attackers with presence in the system an ability to undermine access control restrictions implemented at the operating system level. The vulnerability was originally discovered in Skoda Superb III car with MIB3 infotainment unit OEM part number 3V0035820. The list of affected MIB3 OEM part numbers is provided in the referenced resources.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe MIB3 infotainment unit in certain Skoda and Volkswagen vehicles lacks privilege separation in its proprietary inter-process communication mechanism, allowing processes to bypass OS-level access control restrictions. An attacker with existing system presence can exploit this to escalate privileges or access protected resources.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify MIB3 infotainment unit in vehicleCheck vehicle documentation, infotainment system about screen, or contact dealer to confirm the vehicle is equipped with the MIB3 (Modular Infotainment Matrix 3) head unitAffected if Vehicle uses MIB3 infotainment system from affected Skoda or Volkswagen models
-
Check firmware version via diagnostic interfaceUse manufacturer-approved diagnostic tool (e.g., OBDeleven, VCDS) or authorized dealer service to read the infotainment firmware version from the MIB3 unitAffected if Firmware version cannot be determined or matches unpatched release versions
-
Verify patch installation statusContact authorized Skoda or Volkswagen dealer to confirm whether the vehicle has received firmware updates addressing CVE-2023-29113Affected if Vehicle has not received security-related firmware updates for the MIB3 unit
-
Assess prior system compromiseReview vehicle for signs of unauthorized access or modification, such as unknown software, unusual network connections, or evidence of physical tampering with the infotainment unitAffected if Attacker already has system presence, which is required to exploit this privilege escalation vulnerability
User is affected if the vehicle contains an unpatched MIB3 infotainment unit where the proprietary IPC mechanism lacks privilege separation and the attacker already has initial system access.
