CVE-2024-8357
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 · uneditedVisteon Infotainment App SoC Missing Immutable Root of Trust in Hardware Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Visteon Infotainment systems. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the configuration of the application system-on-chip (SoC). The issue results from the lack of properly configured hardware root of trust. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the boot process. Was ZDI-CAN-23759.
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 vulnerability stems from a missing immutable hardware root of trust in the Visteon Infotainment system's application SoC configuration. Without this hardware-based trust anchor, the secure boot chain can be compromised, allowing an authenticated attacker to bypass authentication and execute arbitrary code during the boot process with elevated privileges.

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 the installed Visteon Infotainment versionRetrieve the firmware version from the infotainment system settings, boot logs, or system information interface. This is typically found under Settings > About or accessible via diagnostic port.Affected if The installed version matches cmu150_na_74.00.324a exactly.
-
Verify the SoC hardware root of trust configurationAccess the SoC (System-on-Chip) configuration settings or documentation. Check whether an immutable hardware-based root of trust is present and enabled in the security configuration.Affected if The SoC configuration shows no hardware root of trust or the root of trust is marked as software-based rather than hardware-anchored.
-
Inspect the secure boot chain integrityReview the secure boot chain configuration in the SoC or UEFI/boot firmware settings. Look for chain validation status from hardware root of trust through each boot stage.Affected if The secure boot chain is not anchored to immutable hardware, or chain validation can be bypassed.
-
Confirm boot authentication statusCheck whether the boot process requires authenticated code execution at each stage. Review boot logs or security audit trails for authentication bypass indicators.Affected if Authentication can be bypassed during the boot process, or no authenticated verification occurs before code execution.
If the installed version is cmu150_na_74.00.324a AND the SoC lacks a hardware-based immutable root of trust with a verified secure boot chain, the environment is affected by this vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement a hardware-based immutable root of trust in the SoC configuration and establish a verified secure boot chain; coordinate with Visteon and the SoC hardware vendor for firmware/configuration updates.
