ROPgadget Tool
|
||
|
|
================
|
||
|
|
|
||
|
|
This tool lets you search your gadgets on your binaries to facilitate your ROP exploitation.
|
||
|
|
ROPgadget supports ELF/PE/Mach-O format on x86, x64, ARM, ARM64, PowerPC, SPARC and MIPS
|
||
|
|
architectures. Since the version 5, ROPgadget has a new core which is written in Python
|
||
|
|
using Capstone disassembly framework for the gadgets search engine - The older version can
|
||
|
|
be found in the Archives directory but it will not be maintained.
|
||
|
|
|
||
|
|
Install
|
||
|
|
-------
|
||
|
|
|
||
|
|
If you want to use ROPgadget, you have to install [Capstone](http://www.capstone-engine.org/) first.
|
||
|
|
|
||
|
|
For the Capstone's installation on nix machine:
|
||
|
|
|
||
|
|
$ sudo pip install capstone
|
||
|
|
|
||
|
|
Capstone supports multi-platforms (windows, ios, android, cygwin...). For the cross-compilation,
|
||
|
|
please refer to the https://github.com/aquynh/capstone/blob/master/COMPILE.TXT file.
|
||
|
|
|
||
|
|
After Capstone is installed, ROPgadget can be used as a standalone tool:
|
||
|
|
|
||
|
|
$ ROPgadget.py
|
||
|
|
|
||
|
|
Or installed into the Python site-packages library, and executed from $PATH.
|
||
|
|
|
||
|
|
$ python setup.py install
|
||
|
|
$ ROPgadget
|
||
|
|
|
||
|
|
Or installed from PyPi
|
||
|
|
|
||
|
|
$ pip install ropgadget
|
||
|
|
$ ROPgadget
|
||
|
|
|
||
|
|

How can I contribute ?
|
||
|
|
----------------------
|
||
|
|
|
||
|
|
- Use Z3 to solve the ROP chain
|
||
|
|
- Add system gadgets for PPC, Sparc, ARM64 (Gadgets.addSYSGadgets())
|
||
|
|
- Manage big endian in Mach-O format like the ELF classe.
|
||
|
|
- Everything you think is cool :)
