Dos4fun Exploit (Pwnable)

Описание

In this video, we exploit a 16-bit DOS EXE binary with a stack buffer overflow vulnerability that arises from an incorrect assumption about Microsoft's newline convention. We write a tiny shellcode to read and print the flag, then return to the shellcode via an intersegment return. A standard procedure is used to leak the stack segment.

Note: Do not simply extract the flag from the video and submit; this goes against the policies of pwnable.kr. Please perform the exploit on the remote SSH service by yourself!
