Github attack lab phase 4
3. It seems the attack lab has been tweaked recently. You should avoid overwrite the next part of the return address in stack. Instead, you can use push instruction to add values to the stack. Try remove touch2 address from the input and use following code. mov $0x2d6fc2d5, %rdi. pushq $0x40180d.Attack Lab Walkthrough.

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. If you look inside the ctarget dump and search for touch2, it looks something like this: \nPhase 3 is kinda similar to phase two except that we are trying to call the function touch3 and have to pass our cookie to it as string \n In the instruction it tells you that if you store the cookie in the buffer allocated for getbuf, the functions hexmatch and strncmp\nmay overwrite it as they will be pushing data on to the stack, so you have ...Files: ctarget Linux binary with code-injection vulnerability. To be used for phases 1-3 of the assignment. rtarget Linux binary with return-oriented programming vulnerability. To be used for phases 4-5 of the assignment. cookie.txt Text file containing 4-byte signature required for this lab instance.
For this phase, we will be using the program rtarget instead of ctarget . This phase is the same as phase 2 except you are using different exploit method to call touch2 and pass your cookie. . 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,We do not condone the use of any other form of attack to gain unauthorized access to any system resources. You will want to study Sections 3.10.3 and 3.10.4 of the CS:APP3e book as reference material for this lab. Instructions.

You can construct your solution using gadgets consisting of the following instruction types, and using only the first eight x86-64 registers ( %rax – %rdi ).
A lab that involves 5 phases of buffer overflow attacks. The first three deal with Code injection attacks and the last two phases deal with return operated attacks. Solutions are described below: Phase 1: Phase one is a simple solution approach.Figure 1 summarizes the five phases of the lab. As can be seen, the first three involve code-injection (CI) attacks on CTARGET, while the last two involve return-oriented-programming (ROP) attacks on RTARGET. 4 Part I: Code Injection Attacks For the first three phases, your exploit strings will attack CTARGET. This program is set up in a way ...For this phase, we will be using the program rtarget instead of ctarget \n.

In phase 1 we are trying to overflow the stack with the exploit string and change the return address of getbuf function to the address of touch1 \n. First we run ctarget executable in gdb, we open the terminal and write \n. gdb ctarget \n. To inspect the code further we run a break on getbuf and run the code: \n
