If CTARGET had been a network server, you could have injected your own code into a distant machine. In Phase 4, you circumvented two of the main devices modern systems use to thwart buffer overflow attacks.Phase 2 involves injecting a small code and calling function touch2 while making it look like you passed the cookie as an argument to touch2 \n.

This phase is the same as phase 2 except you are using different exploit method to call touch2 and pass your cookie. \n. In the pdf it tells you to find the instructions from the table and one of the instructions you will use involve popping rdi register off the stack, \nInstead of injecting code into the 40-byte stack frame, we could also inject the exploit code below the 40-byte stack frame. We could use a mov instruction to set %rdi to the cookie.; We could move the stack pointer by altering %rsp so that when we return with ret we will have the right address.; Note that this solution will cause a segmentation fault in the validation part of the program, but ...Feb 22, 2024 · 1. 1.
