I do not report all the vulnerabilities I find, as I just said.

I confess to being a bit mystified as to how work I do on my own time, uncompensated by anyone else, which work does not create new vulnerabilities but instead merely informs me as to their existence, somehow creates an obligation for me to act on behalf of the vendors who managed to create those vulnerabilities in the first place.

Perhaps you have not had the pleasure of trying to report a vulnerability, losing several hours just trying to find the correct place to send the vulnerability, being completely unable to find a channel with which to send the vulnerability without putting the plaintext for it on the Internet in email or some dopey web form, only to get a response from first-line tech support asking for a license or serial number so they can provide customer support.

Clearly, you have not had the experience of being threatened with lawsuits for reporting vulnerabilities --- not in software running on someone else's servers (which, absent a bug bounty, you do not in the US have a legal right to test) but on software you download and run and test on your own machine. I have had that experience.

No. Finding vulnerabilities does not obligate someone to report them. I can understand why you wish it did. But it does not.

I see you point about it being overly difficult to report vulnerabilities, especially legal threats, that seriously sucks. I guess I believe you have an obligation to make some effort to disclose, but if a project is just irresponsible and won't fix their shit, or will try to sue you, it's out of your hands.

[tptacek]

Somehow my doing work on my own time creates an obligation for me to do more work on behalf of others.

Can't I just flip this around on you and say you have an ethical obligation to spend some of your time looking for vulnerabilities? If you started looking, you'd find some. Why do you get to free-ride on my work by refusing to scrutinize the stuff you run?

> Somehow my doing work on my own time creates an obligation for me to do more work on behalf of others.

To some small extent, yes, though how much work is up for debate. Maintainer's email and PGP public key is right there on the website? Yeah, I think you're obligated. No email you can find, no way to contact them, or are just outright hostile? No, I think you shouldn't have to deal with that.

But I feel like you agree with that, though maybe not in those exact words. After all, you've had to jump through all kinds of hoops to disclose vulnerabilities, been threatened with lawsuits for doing the right thing, and yet you still practice responsible disclosure in almost every case in spite of the burden of effort and potential risk. Aren't you doing it because you think disclosure is the right think to do? That's all I mean by obligation.

EDIT: sorry, not "responsible disclosure," "cooperative disclosure" or whatever term you want to use for disclosing the vulnerability to the maintainer.

I think it is a matter of degree. Here - not sure how this is handled in other countries - it is a crime if you come across an accident and do not attempt to help. And to me this is obviously not only the right thing to do because it is required by law but because there is a moral obligation to do so.

Nobody has to enter a burning car and risk his life but at least you have to call the emergency service or do whatever you can reasonably do to help. And it really doesn't matter whether you are doing your work delivering packages, whether the accident was the fault of the driver because he was driving intoxicated, if somebody else could also help or whatnot.

Discovering a vulnerability is of cause different in most respects - the danger is less imminent, the vendor may have a larger responsibility and so on. But the basic structure is the same - more or less by accident you end up in a situation where there is a danger and you are in the position to help to make the outcome probably better.

So I think one can not simply dismiss that there might be a moral obligation to disclose a vulnerability to the vendor on just the structure of the situation, one has to either argue that there is also no moral obligation in the accident scenario or argue that the details are sufficiently different that a different action - or no action in this specific case - is the morally correct or at least an morally acceptable action.

[tptacek]

Accidents and vulnerabilities are not directly comparable, so a position on vuln disclosure does not necessarily imply a particular position on accident assistance.

I would feel a moral obligation to help mitigate concrete physical harm to victims of an accident. I feel no such obligation to protect against hypothetical threats to computer systems.

Chances are, you recognize similar distinctions; for instance, I doubt you feel obligated to intervene in accidents that pose only minor personal property risks.

[danbruc]

That is also my point of view, severity and other factors matter. But that also seems to imply the same thing for vulnerabilities - discovering a remote code execution vulnerability in Windows might warrant a different action than a hidden master password in an obscure forum software no one really used in a decade. The danger is still more abstract but it can still cause real harm to real people.

IF there is a vulnerability, it might already be in use by hackers. People need to know about it immediately, so they can defend themselves (by closing a port, or switching to a different server or something). Companies need to be encouraged to find and fix this kind of thing without waiting for a embarrass them by finding it.

[tptacek]

I object strongly to your claim that I practice "responsible disclosure", for the reasons stated earlier in the thread.

[lawnchair_larry]

There is no such thing as responsible disclosure. The concept is nonsensical. Also, you're overestimating the consequences of a single bug. The boring reality is that bugs rarely matter.

[woodman]

When you say obligation, do you actually mean that? An obligation is enforced by some sort of penalty, either legal (ultimately a threat of violence) or social (public shaming). There is no incentive for meeting an obligation outside of avoiding punishment, so why would individuals and private enterprises do any infosec work?

[big_surprise]

You assume that your own research machine can't be compromised, nor are the communication channels of the organization at fault.

So, it won't be fixed.

Hopefully only one or two people know about the same flaw you found...

Oh, but you would know ahead of time if concrete physical harm could possibly come to the victim of an accident?

Well good for you! You should probably be in charge of defending all infosec research, since apparently you can't be hacked.

[lawnchair_larry]

This is a fascinating exchange. Now I wonder how much of the general population, or even the tech-but-not-security population thinks like this.
