Attack lab phase 4

phase_2. 首先我们在运行时知道我们需要设置cookie为:0x59b997fa。. 本次我们需要使用return调用touch2,并且调用前需要将参数设置成cookie值。. 我们需要做的是修改我们输入的buf,并且将buf修改成我们需要注入的汇编指令,最后函数返回时直接返回到我们的buf执行 ...

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: \nI have binary Phase that is not returning required result i.e 12. Any suggestions?

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 \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, \nWe would like to show you a description here but the site won’t allow us.We would like to show you a description here but the site won’t allow us.

As can be seen, the first three involve code-injection (CI) attacks on CTARGET, while the last involves a return-oriented-programming (ROP) attack on RTARGET.

Although you did not inject your own code, you were able inject a type of program that operates by stitching together sequences of existing code. You have also gotten 95/100 points for the lab.

If you jumped/returned to the 87 byte inside the LEA (instead of the LEA opcode itself), then yes 3 NOPs and then a c3 ret would have the same effect as 2 NOPs and then a c3 ret. A ret instruction unconditionally overwrites RIP, so it doesn't matter what the program counter was before. answered Oct 28, 2021 at 21:02. denture glue dollar treedevry university financial aid disbursement dates 2023devils lake inmate roster I didn't write the disassembled code of phase_4 here, but it needs "%d %d" input, and first integer should be in range 1<=x<4. So it should be 1,2,or 3. And register %edi has the value 7 at first. After the call of func4, code compare the value of 0x10(%rsp) and %eax So I should know the %eax value after the call of func4.
