Fusée Gelée comprises the Fusée Launcher and Fusée Monitor.
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.
Fusée Monitor uses the original Fusée Launcher together with the `pyudev` library to monitor USB devices on a Linux machine and automatically inject the files into the Switch when it is found.
Installation
The main launcher is "monitor-launcher.py". Only Linux is natively supported (due to udev being Linux exclusive), with the primary idea behind this software being devices like Raspberry Pi running the script constantly, injecting the payload in a matter of seconds by just plugging in your device.
Invoke the launcher with the desired payload as an argument, e.g. sudo python ./fusee-monitor.py payload.bin. Connect a Nintendo Switch in recovery mode via USB. The injection will happen as soon as it is detected.
To use this script automatically on each boot, use sudo crontab -e and add @reboot PYTHONPATH=/_yourglobalpath_/python3.6/site-packages _yourglobalpath_/python3 /_yourglobalpath_/fusee-launcher-master/fusee-monitor.py /_yourglobalpath_/fusee-primary.bin to the end of the file. Make sure all of your paths are global in order for crontab to run them. Make sure you ran crontab as sudo, otherwise the script will fail.
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.

CVE-2018-6242 was also independently discovered by fail0verflow member shuffle2 as the "shofEL2" vulnerability.
