ojail

problem

solution

This netcat just opens up an OCaml shell

In DamCTF, I saw that the solution to one of the challenges was to execute commands from inside of ruby programming language.

Here, I used Sys.command "ls";; to get the ls command output.

Then, I saw a folder named system.

I did Sys.command "ls system";; and saw a flag file

I used cat command on flag file and got the flag.

The flag is cvctf{J41L3d_OOOO-C4mL@@}
