Playpen - is it normal that I have access to


I have been playing around with the playpen and discovered that I could issue commands from rust with Command like ls to look around the system and then cat some config files, etc.

Here is a Playpen link where you can find some examples.

So I just wanted to make sure that this is the intended behaviour and not some security issue. :wink:

I now know that the server runs Arch Linux with an Intel® Xeon® CPU E5-2670 v2 @ 2.50GHz and is running perl 5, version 20, subversion 2 (v5.20.2) :smile:


playpen is sandboxed with a tool call playpen so it should be fine.


Hopefully no one tries to misuse that sandbox as a spam sender…


Yeah I figured it was sandboxed because I could create new files in the working directory but they would get removed after the program exited. But better be safe than sorry :blush:


Unlikely, as playpen only allows system calls from a whitelist and the whole socket family isn’t on there.


See playpen’s github for some docs on how the sandboxing works.
