This is a modified version of Debasis Mohanty's code. The return addresses and the ROP parts are ported from metasploit module exploit/windows/smb/ms08_067_netapi. The exploit utilizes a reverse TCP shellcode from metasploit with a payload size of 380 bytes. The shellcode is used to execute arbitrary code on a vulnerable system. The exploit takes advantage of a vulnerability in the SMB service on Windows systems to achieve remote code execution.
