| Exploit working on v2.0 to v9.2 | |
The spider exploit was found by MathewE and used by Gateway-3DS team to launch their flashcard's Gateway v3.0 payload on 3DS system menu version 2.0.x to 9.2.x.
It uses a vulnerability in webkit browser (code name Spider) to load a ROP chain using javascript and DOM which allows loading a file from SD card (usually the Launcher.dat file).
This vulnerability has been fixed in System menu version 9.3.0
Description
The exploit uses 5 different ROP chains based on the browser's version, detected using the user agent string.
- 3DS System version 2.0 = "Mozilla/5.0 (Nintendo 3DS; U; ; en) Version/1.7412.US"
- 3DS System version 2.1-3.X = "Mozilla/5.0 (Nintendo 3DS; U; ; en) Version/1.7455.US"
- 3DS System version 4.0-4.X = "Mozilla/5.0 (Nintendo 3DS; U; ; en) Version/1.7498.US"
- 3DS System version 5.0-7.0 = "Mozilla/5.0 (Nintendo 3DS; U; ; en) Version/1.7552.US"
- 3DS System version 7.1-9.2 = "Mozilla/5.0 (Nintendo 3DS; U; ; en) Version/1.7567.US"
A 6th version is served for browsers with a non compatible user agent.
By visiting the webpage, it checks the user agent and serves the corresponding page based on the user agent. The ROP chain loads the Launcher.dat file located on SD card.
Usage
Place the Launcher.dat file (Gateway v3.0 or newer) you want to boot on the root of your SD card, and visit http://go.gateway-3ds.com to trigger the exploit.
Custom Projects
Since the release of this exploit by Gateway 3DS team, users analyzed how this exploit works and extracted all the different user agent's ROP payload.
The ROP payload has been reverse engineered by Yifan Lu.
In attempt to make this Gateway launching method portable and not always rely on internet access, users ported this exploit to multiple supports such as Android or offline private web servers.
As the filename target to load from SD Card is included in the javascript ROP chain, users can keep multiple version of launcher.dat files (either exploit or homebrew) on their SD card and select the one to launch by visiting different custom web pages.
You can find a list of custom projects, sources or websites based on the Spider exploit.
