## Fusée Launcher
The Fusée Launcher is a proof-of-concept arbitrary code loader for a variety
of Tegra processors, which takes advantage of CVE-2018-6242 ("Fusée Gelée")
to gain arbitrary code execution and load small payloads over USB.
The vulnerability is documented in the 'report' subfolder; more details and
guides are to follow! Stay tuned...
### Use Instructions
2018-05-09 18:51:46 +02:00
The main launcher is "fusee-launcher.py". Linux and macOS are natively supported with Windows support coming Soon™.
With a Tegra device in RCM and connected via USB, invoke the launcher with the desired payload as an argument, e.g. `./fusee-launcher.py payload.bin` . Linux systems currently require either that the Tegra device be connected to an XHCI controller (used with blue USB 3 ports) or that the user has patched their EHCI driver.
