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.

Interpreter Pattern: Given a language, the interpreter pattern can define a representation of its grammar and provide an interpreter at the same time. Clients can use this interpreter to interpret sentences in this language. The interpreter pattern will describe how to interpret these statements using pattern design after having a simple grammar. The language mentioned in the interpreter mode refers to any combination that any interpreter object can interpret. In the interpreter mode, a hierarchical structure of command classes representing grammar needs to be defined, that is, a series of combination rules. Each command object has an interpretation method, which represents the interpretation of the command object. Any permutation and combination of objects in the hierarchy of command objects is a language.
