Let's discuss the pwn challenge

I haven't completed the exploit part, but this should lead you; Leak heap → leak libc → off-by-one overwrite → brute-force stack alignment → return to libc → get the flag.

These hints should be enough to show you the path finishing the exploit part. Enjoy

My instance always gets fcked up! lol

1 - heap leak
2 - libc leak
3 - rbp leak
4 - stack pivot --> new rbp with off by null
5 - rop chain
6 - hijack execution flow


All steps are done and I got the flag(while loop) but my script is unstable . When I use off by null and pivoting on stack , process crashes .

What am I missing? any hint
