In this example, the attacker's aim is to execute a system call "int 0x80" to open a new command line window. To do this, an attacker needs to modify the contents of the eax register to "0x0000000b" and the ebx register to the string "/bin/sh" before "int 0x80" is called, and the ecx and edx registers must point to the value "0x00000000". Suppose the value "0x0000000" and the string "/bin/sh" can be found in memory when the program is running. An attacker needs to construct the value "0x0000000b" himself. However, for the value "0x0000000b", when an attacker saves data to the stack through a buffer overflow, the "0x00" byte will trigger the system to terminate the read operation. This example specifically describes how the attacker uses the existing code snippet in the program to modify the value of val pushed into the stack by the attacker step by step from "0xffffff0b" to the value required by the system call "0x0000000b", thus implementing JOP attack. The following are the detailed steps of the process.剧场版The load method returns the module's exports object after loading, compiling, and caching the module. This is why only methods defined on the exports object in the circle.js file can be called externally.两个人的特别的“约会”开始了——
