ROPgadget
→ View on GitHubAI Summary: ROPgadget is a tool designed to facilitate Return-Oriented Programming (ROP) exploitation by allowing users to search for gadgets within binary files. It supports multiple file formats (ELF, PE, Mach-O, Raw) and architectures (x86, x64, ARM, ARM64, MIPS, PowerPC, Sparc, RISC-V 64) and employs the Capstone disassembler for efficient gadget identification. Notable features include customizable search parameters, ROP chain generation, and support for various opcode and string searching capabilities.
README
ROPgadget Tool
This tool lets you search your gadgets on your binaries to facilitate your ROP exploitation. ROPgadget supports ELF/PE/Mach-O/Raw formats on x86, x64, ARM, ARM64, PowerPC, SPARC, MIPS, RISC-V 64, and RISC-V Compressed architectures.
Install
The easiest way is installing ROPgadget from PyPi:
$ sudo apt install python3-pip
$ sudo -H python3 -m pip install ROPgadget
$ ROPgadget --help
Alternatively you can install ROPgadget from source. You have to install Capstone first.
For the Capstone’s installation on nix machine:
$ sudo apt install python3-pip
$ sudo -H python3 -m pip install capstone
Capstone supports multi-platforms (windows, ios, android, cygwin…). For the cross-compilation, please refer to the https://github.com/capstone-engine/capstone/blob/master/COMPILE.TXT file.
After Capstone is installed, ROPgadget can be used as a standalone tool:
$ python3 ROPgadget.py --help
Or installed into the Python site-packages library, and executed from $PATH.
$ sudo -H python3 setup.py install
$ ROPgadget --help

How can I contribute ?
- Add system gadgets for PPC, Sparc, ARM64 (Gadgets.addSYSGadgets()).
- Support RISC-V 32-bit.
- Handle bad bytes in data during ROP chain generation.
- Manage big endian in Mach-O format like the ELF class.
- Everything you think is cool :)
