It took me a lot of workР’В to create an ISO file that reproduce this bug,Р’В using only Python, PРµСљСљrypto, and a PowerPC toolchain, and I learned a lot of interesting lessons. (To my surprise, this bug was introduced by respected exploit writer comex in September 2013.) Better still, thereРІР‚в„ўs a IOCTL_WRITEHCR implemented in the same method with the same bug, allowing memory corruption. The classic byte/word mixup allows reading from anywhere up to index 511 in aР’В 128 element array. The catch, of course, is in the definition: class CWII_IPC_HLE_Device_sdio_slot0 : public IWII_IPC_HLE_Device

This code looks great, itРІР‚в„ўs bounds checked and everything. INFO_LOG(WII_IPC_SD, 'IOCTL_READHCR 0x%08x - 0x%08x', reg, val) WARN_LOG(WII_IPC_SD, 'IOCTL_READHCR out of range') U32 BufferOut = Memory::Read_U32(_CommandAddress + 0x18) U32 BufferIn = Memory::Read_U32(_CommandAddress + 0x10) U32 Cmd = Memory::Read_U32(_CommandAddress + 0xC) After a little exploring, I came across the following codeР’В (abbreviated): CWII_IPC_HLE_Device_sdio_slot0::IOCtl(u32 _CommandAddress) This provides a considerable attack surface, and is where I began my search for interesting bugs. Instead of requiring a copy of IOS to be fully emulated, Dolphin provides high-level (C++) implementations of all the functionality that IOS usually provides to games. This is implemented usingР’В a number of memory-mapped I/O registers. IPCР’В stands for inter-processor communication, and is the means by which the PowerPC processor running the game code communicates with IOS. This provides a variety of services, for example allowingР’В games to read and write files, and communicate over the network. It runs on a separate ARM coprocessor in the Wii. IOS is the operating system that the Wii provides to games running on it. (IРІР‚в„ўve included links to the WiiBrew wiki, which was a valuable source.)

In Part 1,Р’В IРІР‚в„ўll show how toР’В make a 100% reliable exploit for Dolphin on macOS, which is portable to every version containing a single, simple bug.

I do call it РІР‚СљexploitationРІР‚Сњ, because the same techniques can work on software which actually has security requirements.Р”Р„nyway, enough disclaimers, letРІР‚в„ўs dig in. These issues are not РІР‚СљvulnerabilitiesРІР‚Сњ, itРІР‚в„ўs just a collection of interesting tricksР’В that allow games running on Dolphin to execute arbitrary code. These bugs will be fixed, but there will be plenty of other bugs in the future. I f you run something in Dolphin you should understand that it can do anything on yourР’В computer. Piracy is a very goodР’В way to get yourself hacked. You should not use it to emulate software from untrusted sources. To be clear, Dolphin is not a sandbox, and is not designed to be secure. This has been an interest of mine since I spent some time exploiting a partial GameCube emulator in the last Defcon CTF finals, and I decided to actually explore it following a tweetР’В from a Dolphin developer. In the interests of learning more about Dolphin, Wii, PowerPC, and exploitation, I discovered a handful of bugs, and created an ISO file that can run arbitrary code on the host, portably and reliably. Dolphin is a Wii emulator, and a consistent source of interesting technical problems.
