Hot Take:

Microsoft Azure’s service tags are like those mysterious buttons on a blender: easy to misunderstand, potentially messy if misused, but perfectly functional if you follow the manual. Hats off to Tenable for pointing out the blender’s hidden smoothie mode!

Key Points:

  • Tenable Inc. alerted Microsoft to a potential cross-tenant access vulnerability in Azure’s service tags.
  • Microsoft acknowledged the issue, rewarded Tenable, and updated the documentation.
  • Service tags should not be treated as security boundaries but as routing mechanisms.
  • Authentication is key to preventing any cross-tenant access issues.
  • Microsoft’s response included documentation updates and a coordinated disclosure with Tenable.
