lab, students are given a program with a buffer-overflow vulnerability; their task is to develop a return-to-libc attack to exploit the vulnerability and finally to gain the root privilege. In addition to the attacks, students will be guided to walk through several protection schemes that...
Return-to-libc Attack 学习目标是获得关于缓冲区攻击的有趣变种的一手体验;此攻击可以绕过当前在主要Linux操作系统中实现的现有保护方案。利用缓冲区过度漏洞的常见方法是使用恶意shellcode将缓冲区过度流动,然后导致易受攻击的程序跳转到存储在堆栈中的shellcode。为防止这些类型的攻击,一些操作系统允许系统管理员使堆栈...

Return-to-libc Attack Lab 实验目的:绕过栈保护机制,通过缓冲区溢出,获取ubuntu12的root权限 为了对抗缓冲区溢出漏洞,一般linux操作系统允许管理员设置栈不可执行, 这将直接导致将程序控制权直接跳转到shellcode无法运行,造成攻击失败。 为了对抗不可执行栈,聪明的黑客提出了return-to-libc攻击。攻击者不需要可执行的...
