I don't really agree. Maybe I do, but I probably have mixed feelings about that at least.

DoS is distinct because it's only considered a "security" issue due to arbitrary conversations that happened decades ago. There's simply not a good justification today for it. If you care about DoS, you care about almost every bug, and this is something for your team to consider for availability.

That is distinct from, say, remote code execution, which not only encompasses DoS but is radically more powerful. I think it's entirely reasonable to say "RCE is wroth calling out as a particularly powerful capability".

I suppose I would put it this way. An API has various guarantees. Some of those guarantees are on "won't crash", or "terminates eventually", but that's actually insanely uncommon and not standard, therefor DoS is sort of pointless. Some of those guarantees are "won't let unauthorized users log in" or "won't give arbitrary code execution", which are guarantees we kind of just want to take for granted because they're so insanely important to the vast majority of users.

I kinda reject the framing that it's impossible to categorize security vulnerabilities broadly without extremely specific threat models, I just think that that's the case for DoS.

There are other issues like "is it real" ie: "is this even exploitable?" and there's perhaps some nuance, and there's issues like "this isn't reachable from my code", etc. But I do think DoS doesn't fall into the nuanced position, it's just flatly an outdated concept.

I am kind of sympathetic to that view. In practise i do find most DoS vulns to be noise or at least fundamentally different from other security bugs because worst case you get attacked, have some downtime, and fix it. You dont have to worry about persistence or data leaks.

But at the same time i don't know. Pre-cloudflare bringing cheap ddos mitigation to the masses, i suspect most website operators would have preferred to be subject to an xss attack over a DoS. At least xss has a viable fix path (of course volumetric dos is a different beast than cve type dos vulns)

There are good reasons for that history which are still relevant today.

We have decades of history of memory corruption bugs that were initially thought to only result in a DoS, that with a little bit of work on the part of exploit developers have turned into reliable RCE.
