用C语言编写，分别攻击了Warftp和ccproxy两个漏洞（这两个漏洞只在windows xp sp2中存在，sp3和win7已经修复。因此需要安装一个sp2的虚拟机），攻击完成后，会弹出一个攻击成功的对话框，程序比较基础，但是能够帮助初学者深刻了解缓冲区溢出的原理。(Using C language, were attacked Warftp and ccproxy two vulnerabilities (both vulnerability only exists in windows xp sp2, sp3 and win7 has been repaired, so you need to install a virtual machine sp2), and after the attack is completed, it will pop up a successful attack dialog program basis for comparison, but a deep understanding of the principles that can help beginners buffer overflow.)
