oscp_靶场练习_Lame

1. nmap扫描：

└─# nmap 10.10.10.3                                                                                      
Starting Nmap 7.92 ( https://nmap.org ) at 2023-02-20 23:21 EST
Nmap scan report for 10.10.10.3
Host is up (0.22s latency).
Not shown: 996 filtered tcp ports (no-response)
PORT    STATE SERVICE
21/tcp  open  ftp
22/tcp  open  ssh
139/tcp open  netbios-ssn
445/tcp open  microsoft-ds

看端看情况是Windows系统。

2. nmap使用默认的脚本进行安全性检测

3. 22端口利用

使用hydra 对ssh 22端口爆破，略…

4. 139,445端口利用

445端口的理解与利用：

smbclient匿名登陆尝试
smbclient -N -L 10.10.10.3  -N 匿名无密码登陆， -L 列出目标主机的共享
smbclient -N //10.10.10.3/tmp
smb: \> ls # 列出共享目录ls中的内容

nmap看到samba是3.0.20版本，使用msf进行payload搜索利用：

发现漏洞模块利用成功：
