x64でDynamic ROP + Return-to-vulnによるASLR+DEP+RELRO回避をやってみる - ももいろテクノロジー
「x64でDynamic ROPによるASLR+DEP+RELRO回避をやってみる」では、libcバイナリを読み出しその中に含まれるgadgetを利用してROPを行うことでシェル起動を行った。 しかし、コンパイラによっては実行ファイルにleave命令が存在しない場合があり、このような場合にはleave命令を使ったstack pivotを行うことができず、次のROPシーケンスに実行を移すことができない。 そこで、ここではstack pivotを行う代わりに同一の脆弱性を複数回利用することで、x64環境かつASLR+DEP+RELROが有効な条件下でのシェル起動をやってみる。 また、ここではこの方法を便宜上Return-to-vulnと呼ぶことにする。 環境 Ubuntu 12.04 LTS 64bit版 $ uname -a Linux vm-ubuntu64 3.11.0-15-gener

Beat SMEP on Linux with Return-Oriented Programming | falken's blog
Beat SMEP on Linux with Return-Oriented ProgrammingIntroduction In this post, I will show you how easy it is to use Return-Oriented Programming in the Linux kernel and how it can bypass protections such as SMEP, available in the next generation of Intel processor. Linux buggy module In order to simplify exploitation I have decided to develop a buggy driver containing a stack overflow. Here is the
Bypassing IDS with Return Oriented Programming
Title: Bypassing IDS with Return Oriented Programming Date: 2011-10-02 Author: Jonathan Salwan | twiter: @JonathanSalwan Small reminder of the polymorphism ================================== Polymorphism is used in the shellcode to hide attacks on a network. It is true that today the IDSs (Intrusion Detection System) recognizes most shellcode structures. (example: push /bin/sh, etc). But polymorph

Windows 8 introduced a number of exploit mitigation features, including hardening of both the userland and kernel heaps, mitigation against kernel-mode NULL pointer dereferences, and protection against abuse of virtual function pointer tables. One feature that stood out to me appears to be designed to help mitigate exploits leveraging return-oriented programming (ROP). Return-Oriented Programming

This page gathers generic/universal ROP chains that are solely based on gadgets taken from a single dll. The main requirements for a ROP chain to be listed here are: it must work on XP, Vista, Windows 7, 2003 and 2008 server. (the dll should not rebase and should not be ASLR enabled). If your ROP chain only works on one of the listed operating systems, it must be based on a commonly used module. t
