## 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, and macOS are all natively supported! It's mildly more complicated on Windows, so more indepth usage instructions are on the way.
|
||
|
||
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.

CVE-2018-6242 was also independently discovered by fail0verflow member

shuffle2 as the "shofEL2" vulnerability-- so that's awesome, too.
