NVD · unedited
Visteon Infotainment REFLASH_DDU_FindFile Command Injection Remote Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Visteon Infotainment systems. Authentication is not required to exploit this vulnerability. The specific flaw exists within the REFLASH_DDU_FindFile function. A crafted software update file can trigger execution of a system call composed from a user-supplied string. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-23420.

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

This is a command injection vulnerability in Visteon Infotainment systems specifically within the REFLASH_DDU_FindFile function. Attackers with physical access can craft malicious software update files containing user-supplied strings that get executed via system calls, achieving arbitrary code execution in the device context without authentication.

MitigationSince this is a firmware-level command injection in the update mechanism, remediation requires a vendor-supplied patch with secure input validation in the REFLASH_DDU_FindFile function, along with cryptographic signing of update files to prevent tampering. Physical access controls should also be considered as a compensating control.

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. Identify the Visteon Infotainment system version
    Access the device settings or system information menu on the infotainment unit, or inspect the firmware metadata if you have access to the device firmware image. Look for the version string which typically appears as cmu150_na_XX.XX.XXX
    Affected if The displayed version is exactly cmu150_na_74.00.324a
  2. Locate the firmware version string programmatically
    If you have shell access or can extract the firmware, search for the version string in the firmware binary or system files. Common locations include /etc/version, /var/log/messages during boot, or within the bootloader configuration
    Affected if The version string matches cmu150_na_74.00.324a exactly
  3. Verify the REFLASH_DDU_FindFile function exists
    If you can analyze the firmware binary, search for the string REFLASH_DDU_FindFile or inspect the firmware update mechanism code for the presence of this function handling file operations in the update process
    Affected if The function REFLASH_DDU_FindFile is present in the firmware and processes user-supplied strings from update files
  4. Check if software update functionality is exposed
    Examine whether the device exposes USB or SD card-based software update ports, or if the REFLASH mechanism can be triggered without authentication. This may require physical access to the device debug ports or update interfaces
    Affected if The device allows unsigned or unvalidated software update files to be loaded via physical access

You are affected if your Visteon Infotainment system runs exactly version cmu150_na_74.00.324a and supports the software update mechanism where the REFLASH_DDU_FindFile function processes update files.
