在Windows 10上创建缓冲区溢出 [英] Creating a buffer overflow on windows 10

问题描述

很快，我打算在我的课堂上做一个演讲(攻读计算机科学学位)，在这里我想举一个缓冲区溢出及其原因的基本示例.但是，我无法使缓冲区溢出正常工作.

Soon, I am due to be giving a presentation to my class (doing a degree in computer science) where I want to give a basic example of a buffer overflow and why it's a problem. However, I can't get my buffer overflow to work.

问题是，即使导致进程崩溃，进程也将终止，即使该进程已附加到xdbg之类的调试器上(在VS中，也会引发异常).我认为这是Windows 10内置的一种保护引起的.我仔细阅读了以下文章，尝试禁用它们，并确保在项目属性中禁用/GS的情况下编译项目，但是问题仍然存在.

The issue is that as soon as the crash is caused, the process is terminated, even if the process is attached to a debugger like xdbg (in VS, an exception is thrown). I think this is caused by one of the protections built into Windows 10. I have gone through the following article trying to disable them and made sure to compile the project with /GS disabled in the project properties, but the problem is still happening.

利用漏洞保护功能已禁用

代码如下:

#include <iostream>
#include <string>
using namespace std;

int main()
{
    string input;
    char overflow[5];
    cin >> input;
    strcpy(overflow, input.c_str());
}
