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

The main launcher is "fusee-launcher.py". Windows, Linux, macOS and FreeBSD are all natively supported! Instructions for Windows specifically can be found on the wiki.

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.
