微软IIS5.0/6.0FTP服务远程堆栈溢出漏洞

      Microsoft IIS 5.0/6.0 FTP Server Remote Stack Overflow Exploit (win2k)
      微软IIS5.0/6.0FTP服务远程堆栈溢出漏洞(win2k)

      现在用win2k跑IIS5.0/6.0的服务器估计不多了,2003是主流。
      这个漏洞代码的终极目的是在系统中建立一个以"winown"为用户名,"nwoniw"为密码的账户。
      此漏洞在Windows 2000 SP4上测试通过,影响带有堆栈cookie保护功能的IIS6程序。

    @真好网
    如果你真的找到2k主机,拿下权限那就是系统权限了,而不仅仅是VPS了,哈哈。
    @Tony
    把文章中的代码编译好了工具不就出来了吗。
    @古墓候梅
    就是一个2K下IIS漏洞利用代码,呵呵。
