This is an alternate solution to this challenge. The intended solution is not written here.

Requirements

  • None

Exploitation

The challenge was intended to be a binary exploit challenge, however, due to a small issue, there was another bug in it. So, when you decompile the code using ghidra, you see that the Add command option uses strstr to block certain strings in the input. But, the same ones are not blocked in the Edit command option. The solution seems simple :laugh:.
