We know that in x64, the first six parameters of the function are stored in RDI, RSI, RDX, RCX, R8 and R9 registers in turn. If there are more parameters, they will be stored on the stack. Therefore, in order for the computer to run the commands we want, we need to find a way to put the address of "/bin/sh" into RDI so that the machine can execute the system function. After carefully examining the linux function stack structure, we can find that we can use RAX register to put the system () address into RAX, then look for code fragments with JMP rax to make use of, and at the same time use RDI register to pass the parameter "/bin/sh" to finally achieve the attack purpose.南宋末年，江南少年杨过自小父母双亡，被父亲生前结义兄弟、江湖上有名的大侠郭靖送到天下道教正宗的全真教去学武。全真教教规森严，天性叛逆的杨过在教中吃尽苦头，忍无可忍，终于逃出全真教。被活死人墓中的小龙女收留为徒。师徒二人在墓中一起练武、一起长大，渐生情愫。When an attacker sends an http get request, Slowly sending useless header fields, And never sends the "\ r\ n\ r\ n" end flag, This allows the connection to the web server to be occupied for a long time and ensures that the link is not broken by timeout.
