感谢分享 ! 自己测试了一下，附上自己的poc。
================================================================ 测试平台: Windows XP SP 3 - 5.1.2600 Service Pack 3 Build 2600 (x86) 测试工具: Windbg, Metasploit 测试结论: 1. 让程序崩溃 2. 控制EIP，测试可用ShellCode空间 3. 去掉Bad Chars 4. 准备Shellcode，完成攻击程序 ================================================================ #!/usr/bin/env python
# -*- coding: utf8 -*-

with open(media_file, "w") as f:
