Magic Leap One Exploitation

Overview

This folder contains a (messy) implementation of research exploiting the Magic Leap One.

The fastbooted folder contains the code that runs on the Magic Leap console.

The fastbootrs folder contains a Rust implementation of a Fastboot client, and is the code that runs on the host.

Success

Vulns

This repository contains implementations of two vulns:

  1. Code Execution in CBoot over Fastboot USB by smashing the stack in NVidia's SparseFS parser (sparsehax)
  2. Overwriting CBoot in memory using an oversized kernel-dtb implementation on the storage to gain persistant code execution (dtbhax)

Usage

Warning: It's your responsibility if you brick your console.

You need a siginfo blob (signed list of hashes with a small header) from a firmware update for your device (this is device unique), any partition works as long as it's for your device. Place it in fastbootrs/system-sparse-sig.bin.

Inside the fastbooted/payload directory:

  1. Copy sparsehax.ld to ccplex.ld
  2. Run cargo build-usb-bin
  3. Copy the generated payload.bin file to fastbootrs/src/payload.bin

Put your ML1 console into Fastboot by powering it off, and holding the Vol-Down button whilst powering the console on.

Inside the fastbootrs directory:

  1. Run cargo run --release -- exploit
  2. Success?

If these instructions aren't clear enough, this probably is not ready for you.
