So is HN and every other site in the world insecure because it allows users to post "/etc/hosts" ?

Maybe? I don't know nor care. Assuming that HN has a vuln with path traversal, a sanely configured WAF would block the traversal attempt.

*some traversal attempts

I propose someone who doesn’t know or care how a system works shouldn’t be prescribing what to do to make it secure. Otherwise this is like suggesting every gate must have a lock to be secure, even those which aren’t connected to any walls.

The part that’s not said outloud is that a lot of “computer security” people aren’t concerned with understanding the system. If they were, they’d be engineers. They’re trying to secure it without understanding it.

Good computer security people are engineers.
