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.(1) These lights shall have the following meanings:2-laxativesConn = DriverManager.getConnection (url, username, password);Specify the types of objects to be created with prototype instances, and create new objects by copying these prototypes.
