Students are given a pair of unique custom-generated x86-64 binary executables, called targets, that have buffer overflow bugs.One target is vulnerable to code injection attacks. The other is vulnerable to return-oriented programming attacks.Phase 1 For Phase 1, you will not inject new code. Instead, your exploit string will redirect the program to execute an existing procedure.

In this lab, we need to have at least three machines. We use containers to set up the lab environment. Figure 1 depicts the lab setup. We will use the attacker container to launch attacks, while using the other three containers as the victim and user machines.

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 ...One of the possible solutions to this issue is to push the %rsp value again after returning from the touch function and add more padding. The most import is to review the stack after you perform the operation and make sure it's the same as after your attack is done. 2. Assignees.
