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.
