Ninjhax (sometimes misspelled Ninjahax) is a user mode exploit found by smealum for the Nintendo 3DS game Cubic Ninja. The exploit was initially released November 20, 2014[1], supporting 3DS system menu versions 4.0 - 9.2. One of the system flaws used by ninjhax was subsequently blocked by the 9.3 update[2]. Several months later, on July 18, 2015, smealum released ninjhax version 2.0[3]. This new version added support for system menu versions above 9.2, up to version 10.1. The old version 1 can still be used on lower system menu versions.
Ninjhax makes use of a flaw in the level editor of Cubic Ninja. The level storage format contains sections of variable length that are loaded to fixed-length buffers without length checks[4]. This is used to create a stack buffer overflow, which leads to ROP capabilities. The exploited level can easily be loaded through the QR code sharing feature of the game.
