That’s a scary vulnerability. There’s no mention of the bug bounty paid out for it but I hope it was substantial.

Well at the bottom of the article, they mention that Microsoft first closed the issue as invalid, and on the second attempt they closed it as "cannot be reproduced" (after fixing it).

So from that I can imply there was no payment.

I've reported a trivial way to infer details about passwords in Windows. (Ctrl-arrow in password fields in Windows 8 jumped by character group even when hidden so if a prefilled password was 123 abc.de it would stop after 3, after space (I think), after c, after dot and finally after e.)

All I got was an email: that is interesting bye bye. But it was fixed in the next patch or the next after I think.

So I didn't care to report the two bigger problems I found with Azure Information Protection [1][2] I thought about reporting them but decided against it.

And I will continue to tell people that I don't care to do free work for MS when they won't even give me a t-shirt, a mug or even acknowledge it.

Maybe if one is a security researcher it can be worth it but if you just find something interesting you'll probably be better rewarded by reddit or HN, yes, the upvotes are worthless but less so than a dismissive email.

[1] one in the downloadable AIP tooling where you can easily smuggle clear text information with rock solid plausible deniability - I found it by accident after having implemented a part of a pipeline in the most obvious way I could think of.

[2]: the second had to do with how one can configure SharePoint to automatically protect files with AIP on download, the only problem being if you logged in using another login sequence (sorry for the lack of details, this was before the pandemic and it was just a small part of what I was working on at the time) SharePoint would conveniently forget all about it despite all efforts by me, the security admin at the company and the expert that Microsoft sent to fix it.

It's a feature not a bug: "Azure’s Security Vulnerabilities Are Out of Control" - https://www.lastweekinaws.com/blog/azures_vulnerabilities_ar...

At least this new one seems to have been fixed within two months: 6 Jan to Feb 20th.

The caller still needs at least the Reader role, so it was limited to accounts that were added to the Azure subscription as only Readers.

I'm glad they fixed it, but this doesn't seem too scary??

Suppose user U has read access to Subscription S, but doesn't have access to keyvault K.

If user U can gain access to keyvault K via this exploit, it is scary.

[Vendors/Contingent staff will often be granted read-level access to a subscription under the assumption that they won't have access to secrets, for example.]

(I'm open to the possibility that I'm misunderstanding the exploit)
