I don't know the rules of the TryHackMe Advent of Cyber, but I find it a bit strange that it had one of the quests targeting a version of ROS that has been deprecated for the past 5 years and will be completely EOL'd this May.

ROS 2 moved away from the codebase that the quest targeted many years ago.

CTFs are generally puzzles/games, not pentests themselves, so they will deliberately use out of date or misconfigured versions of software so that they are vulnerable in a known way.
