The binary \"goahead\" is the one that has the vulnerable function that recieves the values sent by the POST request. If we open this binary in IDA-pro we will notice that this follows a MIPS little endian format. The function sub_00420F38 in IDA pro is identified to be receiving the values sent in the POST request. The POST parameter \"gateway\" allows to overflow the stack and control the $ra register after 1546 characters. The value from this post parameter is then copied on the stack at address 0x00421348 as shown below.
