## What is CVE-2024-8356?

CVE-2024-8356 is a high-severity vulnerability in Visteon Infotainment, published on 22 Nov 2024. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Visteon Infotainment VIP MCU Code Insufficient Validation of Data Authenticity Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Visteon Infotainment systems. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

The specific flaw exists within the firmware update process of the VIP microcontroller. The process does not properly verify authenticity of the supplied firmware image before programming it into internal memory. An attacker can leverage this vulnerability to escalate privileges execute arbitrary code in the context of the VIP MCU. Was ZDI-CAN-23758.

Weakness: CWE-345 (Insufficient Verification of Data Authenticity)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-8356 and fix it if it is affected.

What it is: CVE-2024-8356 is a high-severity vulnerability in Visteon Infotainment, published on 22 Nov 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-8356 in the wild and no public exploit code.

Affected product: Visteon Infotainment. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. 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.
2. 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.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
