This an exploit for CVE-2015-2426 (MS-078), a Windows kernel local privilege escalation 0day from the Hacking Team archive (email here). It was developed by Eugene Ching / Qavar security. Original contents below:

Summary.

Windows kernel memory corruption exploit leading to privilege escalation.

Tested on Windows 8.1 fully-patched (as of 28 Jan 2015).

Also tested to work against:

  • Google Chrome, up to v40.0.2214.93 (64-bit); and
  • Google Chrome Canary, up to v42.0.2290.6 canary (64-bit)

assuming a suitable RCE in Chrome (simulated via injecting a thread into Chrome)

Main exploit code.

The main exploit is implemented in PIC.c, which is provided as part of a Visual Studio 2013 Express solution.

Building the solution would produce PIC.exe.

Exploit "raw bytes".

We ultimately want to inject the exploit into the target's memory, and directly run it. In order to do that, we need to inject only the relevant instructions (opcodes) and the necessary data.

Hence, we extract the code segment (the opcodes) from PIC.exe, and append the necessary data (the malformed font, font-data.bin) into a sequence of bytes.

This produces the "raw bytes" that we can directly inject into the target and call CreateRemoteThread() on.

This process is automated through the Python script named make-raw-bytes.py. The output is raw-bytes.bin.

Injection into target.

To convert the "raw bytes" into an .exe that actually injects the "raw bytes" into a target, we need to call WriteProcessMemory() & CreateRemoteThread().

This process is handled by make-injector-cpp.py. The output is injector.cpp, a piece of code which, when compiled, takes a target PID and executes the exploit.

Convenience wrapper.

As a convenience, make.bat will produce injector.exe directly by performing the steps described above.

In other words, make.bat will:

  • make-raw-bytes.py
  • make-injector-cpp.py
  • build injector.exe
