ROPGenerator – Tool That Helps You Building ROP Exploits By Finding And Chaining Gadgets Together

ROPGenerator is a tool that makes ROP exploits easy. It enables you to automatically find gadgets or build ROP chains. The current version supports x86 and x64 binaries.OverviewROPGenerator uses the tool ROPgadget (https://github.com/JonathanSalwan/ROPgadget) to extract gadgets from binaries and the barf-project (https://github.com/programa-stic/barf-project) to disassembly them. After gadgets are extracted, it analyzes them in order to compute their semantic and stores them according to their usefullness. Once the analysis is done, you can request ROPGenerator to automatically find gadgets or ROP chains by supplying semantic queries.ROPGenerator is written in python. The tool has python2-only dependencies so it runs under python2 so far.Please note that the current ROPGenerator version is still a beta under active development, therefore it might not work perfectly on some systems.Why using ROPGenerator ?Nice Command Line Interface : Enjoy a nice and smooth CLI with easy-to-use commandsSemantic gadget search : Find your gadgets quickly by only specifying the desired semanticsGadget chaining engine : No suitable single gadget ? ROPGenerator will build ROP chains for youFully automated exploit building : ROPGenerator can build entire exploits… all by itself !InstallationInstall ROPGeneratorYou can download the source and run$ python setup.py install$ ROPGeneratorInstall DependenciesROPGenerator depends on ROPgadget, prompt_toolkit, enum, python-magic, pwntools and barf v0.4.0:python-magic, enum, pwntools barf v0.4.0, and prompt_toolkit packages will be added automaticaly during installationROPgadget will also be installed automatically if you don’t have it already. However, the currently available package on pypi is not up-to-date. Therefore, it will be installed as “ROPgadget4ROPGenerator", a recent fork of ROPgadget.Getting startedROPGenerator is very easy to use !

ROPgadget – This Tool Lets You Search Your Gadgets On Your Binaries To Facilitate Your ROP Exploitation

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.InstallIf you want to use ROPgadget, you have to install Capstone first.For the Capstone’s installation on nix machine:$ sudo pip install capstoneCapstone 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.pyOr installed into the Python site-packages library, and executed from $PATH.$ python setup.py install$ ROPgadgetOr installed from PyPi$ pip install ropgadget$ ROPgadgetUsageusage: ROPgadget.py [-h] [-v] [-c] [–binary ] [–opcode <opcodes>] [–string <string>] [–memstr <string>] [–depth <nbyte>] [–only <key>] [–filter <key>] [–range <start-end>] [–badbytes <byte>] [–rawArch <arch>] [–rawMode <mode>] [–re <re>] [–offset <hexaddr>] [–ropchain] [–thumb] [–console] [–norop] [–nojop] [–nosys] [–multibr] [–all] [–dump]optional arguments: -h, –help show this help message and exit -v, –version Display the ROPgadget’s version -c, –checkUpdate Checks if a new version is available –binary <binary> Specify a binary filename to analyze –opcode <opcodes> Search opcode in executable segment –string <string> Search string in readable segment –memstr <string> Search each byte in all readable segment –depth <nbyte> Depth for search engine (default 10) –only <key> Only show specific instructions –filter <key> Suppress specific instructions –range <start-end> Search between two addresses (0x…-0x…) –badbytes <byte> Rejects specific bytes in the gadget’s address –rawArch <arch> Specify an arch for a raw file –rawMode <mode> Specify a mode for a raw file –re <re> Regular expression –offset <hexaddr> Specify an offset for gadget addresses –ropchain Enable the ROP chain generation –thumb Use the thumb mode for the search engine (ARM only) –console Use an interactive console for search engine –norop Disable ROP search engine –nojop Disable JOP search engine –callPreceded Only show gadgets which are call-preceded (x86 only) –nosys Disable SYS search engine –multibr Enable multiple branch gadgets –all Disables the removal of duplicate gadgets –dump Outputs the gadget bytesScreenshotsDownload ROPgadget
