I'd be careful about posting stuff like this as a young person in Australia. The modern situation is incredibly hostile towards this sort of disclosure. Especially regarding a government entity. It's not that you've done anything in the slightest bit wrong. It's that others with power can easily make it become wrong with little to no backlash in the current Australian climate. I understand the desire for recognition,…
Tried my best to report (not publicly disclose) it, including asking the front desk for contact information for IT; no response.
I think we're (on HN) often in quite a bubble of being (or striving to be) hot on this sort of thing, or frankly far trickier to exploit sorts of things, when really the bar for a lot of ('IT is a cost centre') stuff out there is extremely low.
I don't think this sort of leak or vulnerability is anywhere near as rare (which isn't even that rare) as it seems - I think an awful lot must just get quietly exploited or go unnoticed. We're only hearing about this one because someone thought it was 'lolz', I didn't publicize the one I noticed (in my normal user behaviour of just trying to book a room!) nor did I see if I could connect to the database and book myself in for free or something. And I only noticed it because it a) experienced an error; b) dumped env vars in the event of an error - i.e. I didn't have to look for it. How many other sites have I used since with similar problems but which just didn't happen to serve it up on a silver platter for me?
