Azure App Service Linux source repository exposure

Wednesday, December 22, 2021

MSRC was informed by Wiz.io, a cloud security vendor, under Coordinated Vulnerability Disclosure (CVD) of an issue where customers can unintentionally configure the .git folder to be created in the content root, which would put them at risk for information disclosure. This, when combined with an application configured to serve static content, makes it possible for others to download files not intended to be public.

BlueHat is Back!

Thursday, November 11, 2021

After a short hiatus, BlueHat is coming back with a vengeance! And we’ve got big plans for the entire researcher community. But first, I must apologize. It’s been a while since you have heard from us. We didn’t have BlueHat 2020 or 2021, and we know that was disappointing. It was partly due to the pandemic, where our priority was simply keeping everyone safe.
