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 · unedited
The Real-Time Streaming Protocol implementation in the MIB3 infotainment incorrectly handles requests to /logs URI, when the id parameter equals to zero. This issue allows an attacker connected to the in-vehicle Wi-Fi network to cause denial-of-service of the infotainment system, when the certain preconditions are met. Vulnerability discovered on Škoda Superb III (3V3) - 2.0 TDI manufactured in 2022.

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 · moderate confidence

The MIB3 infotainment system's RTSP implementation contains a flaw in handling requests to the /logs URI when the id parameter is set to zero. An attacker connected to the in-vehicle Wi-Fi network can send a specially crafted request causing the infotainment system to become unresponsive or crash, resulting in denial of service.

MitigationRestrict access to the in-vehicle Wi-Fi network to trusted devices and apply any vendor-supplied firmware updates for the MIB3 infotainment system when available.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm vehicle and infotainment system
    Verify the vehicle is a Skoda Auto Superb 3 and identify the MIB3 infotainment system version. Check vehicle settings or infotainment About/Version menu for system information.
    Affected if Vehicle is not a Skoda Auto Superb 3 or does not use MIB3 infotainment system
  2. Check firmware version
    Locate the firmware version in the infotainment system settings (typically under Settings > System > About or similar). Compare the installed firmware version to the affected version 2022.
    Affected if Firmware version is exactly 2022 (only this specific version is affected)
  3. Verify Wi-Fi connectivity to infotainment
    Check if a Wi-Fi access point is exposed by the vehicle infotainment system. Attempt to connect to the in-vehicle Wi-Fi network if one exists.
    Affected if Wi-Fi network is enabled and accessible from outside the vehicle
  4. Test RTSP endpoint vulnerability
    With a device connected to the in-vehicle Wi-Fi, send a crafted RTSP request to the /logs URI with the id parameter set to zero (e.g., rtsp://<infotainment-ip>/logs?id=0). Observe if the system becomes unresponsive or crashes.
    Affected if The RTSP service responds to /logs?id=0 and the system exhibits denial of service symptoms

The environment is affected only if the vehicle is a Skoda Auto Superb 3 with MIB3 infotainment system running firmware version 2022, the in-vehicle Wi-Fi is accessible, and the RTSP /logs endpoint with id=0 causes a denial of service condition.
