The researcher disclosed the bug one week before Microsoft is scheduled to patch it. I'm sure MS isn't thrilled, but they did drag their feet:

"I decided to release this bug one week before the patch is released, because it is not the first time Microsoft sits on my bugs. I'm doing free work here with them (I'm not paid in anyways for that) with the goal of helping their users. When they sit on a bug like this one, they're not helping their users but doing marketing damage control, and opportunistic patch release."

The researcher sounds really petty. They're patching it, but not on this person's schedule so he's causing microsoft and USERS problems they didn't have before.

If they weren't patching, I'd understand, but this isn't the right way to get attention in my book.

There are very competent people on this planet who make a very good buck out of zero-days (not to mention remotely control users' machines, and steal data). IMO the researcher didn't want that particular vulnerability to dwell on somebody's todo list for several years.

It definitely puts pressure on MS but I don't think that's bad. Corporations have demonstrated time and again that the only way to get them to move is a PR hype.

If they want researchers to stop doing preliminary public disclosures, they should prioritize security higher than PR damage control.

> IMO the researcher didn't want that particular vulnerability to dwell on somebody's todo list for several years.

Except the researcher themselves knew it was one more week, and not "several years." You cannot claim they were ignorant if their own statements shows that they were not.

You might be right. But they only claimed it, didn't they?

I personally like Windows 10 a lot and I applaud any effort to turn it into a long-term stable OS.

Well, if MS claims the patch is coming in one week, one approach might be to wait one week and then release the exploit. Works out regardless of the accuracy of the claim.
Patch Tuesday is the second Tuesday of each month. Unless something odd happens, you can count on the fix being out a week from tomorrow. There's also a justification for this — they sat on it because they were releasing other SMB-related patches on the February Patch Tuesday. I don't really think anybody can reasonably argue that MS would not release the fix next week. But that's not the point.

This bug was reported in December, and there's no reason to believe that they didn't have a patch in time for inclusion in the January Patch Tuesday. They chose to withhold that patch due to non-technical, apparently PR-related, reasons, and the researcher in question is complaining that this has happened before with other bugs reported by him. That's a pretty cavalier approach to security, and early disclosure is the only way the researcher can punish MS for it.

«He told Ars that the software maker initially planned to patch the flaw in December but later decided to delay the release until February so it could be included with other planned SMB fixes.» «it is not the first time Microsoft sits on my bugs»

So they already reneged once on this bug which fits into a previous pattern. If that is right putting pressure on them sounds entirely justified and not at all petty.

Just because there are other people who act totally unethically doesn't mean you get bonus points for doing kinda the right thing.
MS is acting 'totally unethically' by not patching this bug immediately and rewarding the researcher.
Meh. The bug requires you to connect Windows to a malicious SMB server.

Now that everybody knows that, if anybody is really concerned, they can stop SMB connections from LAN to WAN by blocking TCP 139, 445 and UDP 137, 138.

> Now that everybody knows that

Wait, when did everyone become aware of that? I'm willing to bet the vast majority of windows users have no idea. _Some_ people only know _because_ he released the bug.

You're absolutely right! The researcher acted in a questionably ethical manner here by waiting to disclose the vulnerability. The only ethical approach is full and immediate public disclosure.
Full and immediate public disclosure seems irresponsible and counterproductive IMO.

The last thing I'd want as a developer or a manager is to wake up in the morning with a PR shit storm and angry users on my hands because some inane script kiddie found it appropriate to disclose a zero day without reaching out to me or my team first. Sure, some other guy might know about or find the vulnerability and exploit it by the time a patch comes out; it's guaranteed that they will if you release a 0day.

We can discuss all we want on what a reasonable delay to release a patch might be, but absolutely not on the notion that immediate public disclosure is the right thing to do. It wastes everyone' time, disrupts workflows, puts fellow developers, their managers, and their users under intense pressure and stress, all so some kid can enjoy an ego trip. To me it just seems gross and childish.

The last thing I'd want as a developer or manager is to wake up in the morning with a PR shitstorm and enraged users because I shipped some vuln.

What full disclosure does it put everyone on the same footing. Developers, users, and attackers all at once. It reduces the window for potential abuse as much as possible. As policy, it sharpens the incentives to be very careful in your development processes and improve security measures.

It's worth considering that this is actually a long-running historical debate. One of the commonly espoused positions is yours - contact devs privately, give them a reasonable amount of time to patch, then disclose after a patch. After all, it minimizes disruption to production planning and workflows and still protects users. Seems reasonable right? Everyone wins!

Catch is, it's historically been abused by companies more interested in their production schedules than the security of their users. Maybe that's not you! In which case, well done, you're completely awesome! However, this has historically turned out to be rather a lot of software companies.

Full disclosure, the policy I advocated for, seeks to short-circuit this. It offers maximum information to a maximum of people in a minimum of time. It pressures companies to fix their products rapidly and to ship better products in the first place. It also offers users the ability to be aware that they may be under attack and protect themselves in lieu of a patch which may or may not ever come into being.

At the end of the day, the question is this: who are you protecting with your disclosure policy? I would suggest that the policy you have advanced seeks to balance the interests of users and of developers/managers. It's perhaps worth considering that your users may prefer a policy that aligns your incentives more with theirs. Perhaps your customers might prefer policies that encourage a proactive stance.

What would your solution be?
As a longtime windows user: No.

There's no excuse for them to delay patching it without explaining to him in detail why there's a delay, and even if he had been a dick about it, they should've had a very good explanation for the public.

They had neither and that is unacceptable.

Reason being: Even if he doesn't publicize it, someone else might know and be using it without MS knowledge. Anytime you become aware of an exploit one must act as if it already is being abused.

What is the thresshold where you do decide to release the bug description?

Microsoft has sat on bugs for years saying they were working on them. Do you disclose after a week? A Month? a Year?

If it were a company or team with a solid history of patching swiftly I could see trusting them. But this is Microsoft, they have the resources to fix bugs. They chose an OS design that sacrificed security for other things. Worst, they chose to betray trust in the past. Someday Microsoft might earn that trust back, but they are a long way off from earning mine.

If I informed them of the bug and it wasn't fixed in the next patch, then I would need solid evidence they are working on it or I release the exploit. If it were a group I trusted I would follow up several times until I lost faith in them.

I don't know, I guess that really depends on the frequency and context of 'not the first time Microsoft sits on one of my bugs'. I'm not a security researcher but I suppose if I was and Microsoft was sitting on my bugs pretty frequently and they were really serious I might just give them a shot across the bows one fine day.
And when Microsoft do cut QA short people complain that Microsoft doesn't care about quality/is using retail as a beta test. It is really a no-win situation to be honest.
The correct way to do this is immediately release a bulletin to admins to block the affected service, then push a patch to disable it, then push a patch to fix and reenable it when they feel ready.

It's only unwinable because Microsoft refuses to take a PR/cash hit of telling people to stop using something while it's broken.

>The researcher sounds really petty.

We live in the age of security researcher marketing. No one wants to be the anonymous guy who submitted sometnhing. They want to be the star and have all these articles written about them and all this attention. The easiest, of course unethical, way to get this is to release something before its patched regardless of what the OEM is doing in regards to patch scheduling. To release one week before patch Tuesday is a pretty big middle-finger to a lot of people for no other reason than what looks like personal gain or spite.

I imagine this decision is going to bring him a lot of negative attention. I wouldn't hire someone who 0-day'd a security bug a week before its patch out of spite.

Thankfully, connecting to a random smb is a fairly edge case. I believe most firewalls block smb to/from the internet and most consumer ISPs block the protocol outright. This probably won't have much of a real world impact.

Well, I'm not sure I agree in this case.

> He told Ars that the software maker initially planned to patch the flaw in December but later decided to delay the release until February so it could be included with other planned SMB fixes.

Presuming the USERS don't ALREADY have a problem is the inherent flaw in your logic.

A researcher who earns no money finding exploits is at an inherent disadvantage to black hats who DO get funding for selling the exploits they find.

They weren't patching, in this case the process has taken months. It's just marketing so they can say there's just a small number of bugs.
> so he's causing microsoft and USERS problems they didn't have before.

He's not causing problems, he's solving them.

Gifting exploiters a 0day before the KNOWN patch release date, is causing problems.
No, it was only a 0day before he made it public. He is merely providing security-conscious persons information and a way to defend themselves from an exploit which MS has not fixed. He is turning a 0day into a known vuln.
You know who sounds really petty though? The whiners taking Microsoft's side despite them missing the bug in the first place and sleeping on the report, and now attacking the person who reported it.

> They're patching it, but not on this person's schedule so he's causing microsoft and USERS problems they didn't have before.

Not in the slightest. You do not understand how the internet works. The vulnerable systems were vulnerable yesterday, and are vulnerable today because MS didn't think it was worth hurrying to patch them. Users' harm was caused by Microsoft who gave them a broken product, and by any hypothetical hackers, not by a security researcher telling the public what the hackers probably already knew.

Microsoft had a chance to release an emergency bulletin as soon as they were informed of the vuln, with mitigation steps. (ie, block SMB, etc) They didn't, and in fact spent time recommending useless things (Win10, Edge) that only serve to slander competitors by implication, and pimp more of their products.

Microsoft needs the understand that the new timeframe for releasing mitigations, if not patches, is closer to 24h than 24 days. But even if they hit that metric, they don't deserve any fanfare until they do it without lying or misdirecting.

Downvoters: RTFA - The Microsoft reports are intentionally misleading wrt. steps customers need to follow to be safe, and they claim to be better that their competitors (Apple, etc) in this regard despite obvious and consistent proof to the contrary. Microsoft is responding to security concerns with marketing speak, and they're knowingly setting their customers up for catastrophic data loss or hacks by recommending useless fixes.
