MSET exploit
Authorichfly, GateWay

The MSET exploit is an exploit for the System Settings application of the Nintendo 3DS (MSET). The vulnerability was originally discovered by ichfly in 2012, and was later used by the GateWay 3DS. The exploit uses a flaw in the Nintendo DS profile settings, where a long nickname or message will cause a stack buffer overflow, crashing the 3DS part of the console.

The vulnerability used by this exploit was fixed with System Menu version 7.0.0-13.
