I’m sorry, what?
Turns out arbitrary code execution is actually great(!)
it does not have to be arbitrary my dude
Problem is, you’re mixing a number of different concepts into a nonsensical claim.
Exec as an “execute a string as a language instructions” is nothing new nor unique to PHP. Ruby on Rails, for example, uses it in a controlled manner to generate methods on ActiveRecord models.
Exec as an “replace this process with another process” is old news again. It’s not even language specific.
Popen/spawn family (which seems to be what you alluded to) is, once again, nothing new and is used everywhere.
i just meant that python's and node's implementation is shit
