大哥，有人在军中找咱们。在公孙匡押解进京之前，此案也无法审理，等他进京再说吧。Responsibilities of the lead:The above analysis shows that one of the first three situations will inevitably occur after intercepting down, so intercepting down is no longer considered here. Let's look at the difference between events after intercepting down.1. Fix several bugs;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.
